First, the new cases. July 24, 2021 0— — At 24: 00, there were 2 new confirmed cases (all common types) in COVID-19 and 2 new asymptomatic infected cases. Among these 4 cases, Jiangning, Lishui, Jianye and Gaochun each had one case. Up to now, there are 37 confirmed cases in Nanjing (including 14 mild cases and 23 common cases), and there are 20 asymptomatic infections in Nanjing. The relevant information and trajectories of newly confirmed cases and asymptomatic infected persons have been published through WeChat WeChat official account and Weibo such as "Nanjing Publishing" and "Healthy Nanjing".

Second, the medical treatment work. Up to now, 37 confirmed cases have been treated in Tangshan Hospital of Nanjing Second Hospital (Nanjing Public Health Medical Center), and their vital signs are stable. At present, 20 asymptomatic infected people are also in centralized isolation and medical management in Tangshan Campus of Nanjing Second Hospital.

III. Delineation of risk levels. According to the national and provincial requirements for accurate prevention and control of COVID-19 epidemic, the epidemic risk level in some areas of Nanjing has been adjusted since July 25, 2021. Since July 25, 2021, the building area where Wutai Building Materials Store is located at the intersection of provincial road 239 and Yaoding Road in Gaochun District of Nanjing has been adjusted from a low-risk area to a medium-risk area. The risk levels in other regions remain unchanged. From July 25th, 2021, No.26 Suojie, Nanyuan Street, jianye district was changed from a low-risk area to a medium-risk area. The risk levels in other regions remain unchanged. From July 25th, 2021, No.388 Xinling Road, Maoting Community, Lukou Street (medium risk), Shinian Village, Lukou Street (adjusted from medium risk to high risk). The risk levels in other regions remain unchanged. Since July 25, 2021, Xiangzhangyuan in Vanke City, Yongyang Street, Lishui District has been adjusted from a low-risk area to a medium-risk area. The risk levels in other regions remain unchanged.

Close contacts and sub-close contacts with positive people on the same flight must be centralized isolated.

Explanation: that is, if there is a case of positive infection or close contact and sub-close contact of positive infection on a plane, all the people on the same plane should be isolated.

On or after July 10, if there is a history of airport travel in and out of Hong Kong and a record of ticket purchase, standardized home isolation shall be implemented. Do not have the conditions of home isolation, should be centralized isolation.

Explanation: home isolation observation means that it is best to live alone; If conditions do not allow the choice, a well-ventilated room in a house should remain relatively independent as an isolation room, and it is best not to use air conditioning in the room, especially the central air conditioning shared with other rooms; If conditions permit, try to use a separate bathroom and avoid sharing it with other family members. This is home medical observation.

Those who stay at the airport for more than half an hour and enter the lobby but have not touched the public facilities inside the airport should be tested for nucleic acid three times a week according to the specifications. These three times of nucleic acid testing are also required, not three times in a row, but the interval between two times should exceed 24 hours, and three times of nucleic acid testing have been done in various ways, such as mixed sampling at 1: 5 or 1: 10, and the time interval can meet the requirements without re-testing. What about those who have been in contact with the airport? If you have touched it, you should observe it at home.

If you stop at the airport for a short time, within half an hour, and you don’t enter the airport lobby, such as giving someone away or passing by, you can turn it into a green code if the nucleic acid test is negative.

Those who pass through the airport by means of transportation and have never been to the airport can turn green after passing the big data screening. Because in high-risk areas, the degree of risk is still relatively large, and there are still risks, so everyone should be responsible for themselves and the society, and be realistic about their own situation.

As for how to decode these policies, the Nanjing area "Su Kang codeThe transcoding policy is based on the documents issued this time. You can learn how to do the specific transcoding through the 12345 government hotline, and there will be a corresponding team to do this, so as to provide you with a more convenient and convenient process.

Yesterday, the Center for Disease Control and Prevention in jianye district reported that a citizen’s initial screening result of nucleic acid test was positive (this citizen was engaged in ground work at Lukou Airport, and now he was diagnosed as an ordinary case and was treated in isolation in a designated hospital in Nanjing). jianye district immediately launched an emergency plan and took the following measures:

The first is to carry out flow adjustment and control personnel classification. As of 0: 00 today, through the flow adjustment, there are 44 close-contact and sub-close-contact personnel in jianye district, who have been transported in strict accordance with the protection regulations and concentrated on medical observation. All the secret and sub-secret personnel outside the area shall be notified to the local area for isolation management. There are 17 people in 8 households in the same unit of this person’s residence, and all of them are centralized and isolated according to the close contact personnel.

The second is to implement closed management of the community, and other people in the community conduct home health monitoring.

The third is to carry out nucleic acid sampling and testing. By the end of 0: 00, 1178 people were sampled from the close contact personnel, the sub-close contact personnel and the people in the residential area, and 46 samples were sampled from the environment such as the residence, corridor and elevator of this case. All the test results were negative.

The fourth is to carry out environmental disinfection. The residence, building and unit of the case were disinfected.

The fifth is to classify and deal with community garbage. The garbage generated by the case family and the protective articles used by the staff involved in closed management are treated as medical wastes; Other garbage generated by residents in the community will be collected and treated separately by special personnel every day.

The official propaganda is 400km. Actually, it’s about 360-370km once tried, and it’s a little worse in winter, almost the same as the official propaganda. Anyway, I’m going to charge it when I have about 100 left, and it’s charging quickly. Accuracy of battery life: the battery life is relatively accurate. It has been running for more than 3,000 kilometers by car. In most urban areas, the power consumption is about 16kw per 100 kilometers, which is not bad. In terms of energy consumption, the advantages of new energy sources are not highlighted!

For a girl like me, the space can be described as spacious. Haha, I am 165 in height and 120 kg in weight. Sitting in the car, no matter my head or legs, there is enough room for activities, and I don’t feel narrow at all, because I will take a few girlfriends out to drink milk tea and go shopping on holidays. They also praised me that this car doesn’t look big. In fact, it is quite spacious when sitting. If you are motivated, if you don’t pursue accelerated passion, its performance is still quite awesome. When waiting for the traffic lights, it is often faster than the car next to it, and the acceleration is very smooth. It may be inferior to those fuel cars at high speed, but basically it can crush all kinds in the urban area. After all, it is an electric motor.

If you look at the appearance, you still have to look at your personal preference. I just prefer this cute style. The more you look at it, the better it looks. When you drive out beautifully, the whole person’s mood will be better. As for the car, it is mainly because you like it. This is the most important thing. The workmanship of the interior is still exquisite, especially the handling of some details, and the joints of the gaps are handled very delicately. It makes you feel that it is not cheap at all, and the materials are very kind, and most of them are covered with soft materials. The visual effect is awesome! Another place worth mentioning is that the intelligent system is really convenient to use and has all kinds of functions. Novices can also control it quickly.

A car with super high cost performance, I don’t think there is anything more worthwhile than it at the same price. If I choose it again, it will still be a good cat. It’s too convenient to reverse the car. Lateral reversing is the shortcoming of many girls. With this, I can easily get in and feel powerful again. Convenience of wireless charging of mobile phone: Although this wireless charging is a bit slow, it improves the convenience and sense of technology of a good cat. App remote control: the remote control is too powerful. In summer, it is set to cool down quickly for 5 minutes before work. How high the temperature is, it will be full of coolness. This is really friendly to the owner. I forgot to bring my key when I changed my bag, and I started the vehicle directly by APP Bluetooth unlocking, and there was no anxiety in an instant.

The steering accuracy of the steering wheel is quite high, which is called a smooth operation. The steering wheel is relatively light, but it won’t make people feel mad, and the steering accuracy is also very high, giving people a practical feeling. The brake is completely determined by the intensity of the individual’s foot stepping, which is easy to control and the design of the seat is very ergonomic. Sitting on it feels good, and the shock absorption is not too hard, so the filtering of road vibration is relatively complete, at least it won’t make you feel particularly bumpy. Although the sound insulation is not particularly perfect, at least when driving often, the people inside the car will not be affected.

This car has three shortcomings:

The first disadvantage is the price of this car. I didn’t give a discount when I bought it. I feel a little worse about the price/performance ratio, but who will like it? Book early, pick up the car early and enjoy it early.

Secondly, due to work reasons, I often drive this car to some places with uneven roads. I feel that if I take that bad road, the sense of bumps is still quite obvious.

Thirdly, I think its disadvantage is probably that the sound insulation effect is not very good. It feels ok if you run at a low speed in the urban area, but if the speed is faster, you can hear more obvious noise. I am very sensitive to hearing, so I feel the need to spit it out.

Old streets, old hospitals, old houses, old facilities and poor living environment are common worries of many residents in old residential areas, and they are also a long-standing problem in urban management. How to solve the dilemma of "four old and one poor" in old communities? At the briefing on the State Council policy held by the State Council on July 1st, Yan Huang, Vice Minister of Housing and Urban-Rural Development, said that the renovation of old urban communities would be comprehensively promoted in accordance with the requirements of the Central Urban Work Conference, the Government Work Report and the deployment of the the State Council Executive Meeting.

More than 10,000 elevators were installed last year.

According to Yan Huang, the old urban community refers to the residential community where the city or county has been built for a long time, the aging problem of municipal supporting facilities is prominent, and public services are lacking. The main problems are dilapidated pipe network, lack or serious aging of water supply and drainage, power grid, gas and optical fiber facilities; Many old communities not only lack public services such as providing for the aged and caring for the young, but also have problems in the storage of motor vehicles and non-motor vehicles. Lack of property management, poor public environment, damaged roads, unauthorized construction, etc.

Take installing an elevator as an example, such as a six-story building, the higher the floor, the stronger the residents’ willingness to install an elevator; However, in the view of residents on the first floor or the second floor, where the demand is relatively urgent, elevators occupy public space, and their interests are more or less damaged, which leads to the slow progress of elevator installation.

"In the face of these practical long-term problems, the experience summed up by practice in various places is that we must adapt to local conditions, one building and one plan, or even one building and one plan, and do the mass work in detail." Yan Huang said that the design and construction scheme of installing elevators should take into account the reasonable demands of residents at all levels as far as possible, and try to maximize the benefits and minimize the impact through meticulous personalized design. At the same time, she pointed out that it is "urgent" to install elevators in old communities, and the Ministry of Housing and Urban-Rural Development is vigorously promoting it, but the key is to rely on residents’ neighborhood consultation and participation to reach an agreement.

The reporter learned that in recent years, Beijing, Shanghai, Guangzhou, Hangzhou and other cities have made a lot of active explorations in installing elevators in old communities. "Up to now, the progress has been relatively smooth, and most residents are quite cooperative, and the results achieved are also very gratifying." Yan Huang said that in 2018, more than 10,000 elevators have been installed in old residential areas nationwide, more than 4,000 are under construction, and more than 7,000 are going through preliminary procedures, and the installation of elevators in old residential areas is being pushed forward in an all-round way.

It covers a large area and involves hundreds of millions of residents.

It is understood that at present, the old urban communities that need to be rebuilt in the country involve hundreds of millions of residents, with a large area and different situations. How to grasp the content of old community reconstruction?

According to Yan Huang, the renovation of old residential areas is currently divided into three categories. The first is to ensure basic supporting facilities. For example, the maintenance and improvement of municipal infrastructure such as water, electricity, gas and roads that are directly related to residents’ lives in old communities, as well as the installation of elevators and garbage sorting facilities. Second, on the basis of ensuring basic conditions, encourage qualified areas to build public activity venues, parking lots, activity rooms and property houses during the transformation. The third is to further improve the facilities and public services in the community such as providing for the aged, caring for the young, cultural rooms, medical care, food assistance, housekeeping, express delivery, convenience and convenience stores.

"Considering the large regional differences, all provinces, including districts and cities, can make a list of contents that need to be transformed in cities or communities according to the actual situation and needs." Yan Huang said.

Transforming historical and cultural blocks like "embroidery"

Some old urban communities are located in historical and cultural blocks, bearing many precious historical memories. Regarding how to coordinate the relationship between the renovation of old residential areas and the inheritance of urban history and culture, Yan Huang said that we should treat historical heritage well and carry out fine construction, operation and maintenance.

Yan Huang pointed out that in the future, the repair, maintenance and transformation of qualified historical and cultural blocks can be coordinated with the transformation of old urban communities. At the same time, she stressed that the transformation of historical and cultural blocks is different from that of ordinary old residential areas, and in particular, several key points should be followed: First, historical and cultural blocks retain more historical information, and all the protection should be ensured during the transformation process to avoid "one demolition, big demolition and big construction"; Second, some historical and cultural blocks have made great efforts in local and small-scale transformation, and should be coordinated with the overall style in the process of transformation design; The third is to promote protection through rational utilization.

"The most important thing is to promote the renovation and repair of historical and cultural blocks like’ embroidery’, treat these very valuable historical heritages well, and be refined from construction, design to operation and maintenance." Yan Huang said.(Reporter Qiu Wei)

The early warning information of heavy pollution weather is released or released by the office of the provincial heavy pollution weather emergency command center, and the information is sent to the people’s government of the emergency response city, and the information is also released to the media and the public. The people’s governments of all districts and cities shall, according to the instructions of the Office of the Emergency Command Center for Heavy Pollution Weather or the changing trend of air quality in this Municipality, designate relevant departments to issue or remove early warning information for heavy pollution weather.

VI. Job Requirements

(1) Strengthen leadership and make careful arrangements.Construction, urban management, ecological environment and other departments at all levels should fully understand the importance of prevention and control of dust pollution in construction sites, do a good job in classified management and control, and implement the policy of exemption from management and control, not only to ensure the control of atmospheric environment, but also to support the smooth progress of engineering construction projects. It is necessary to do a good job in the classification and grading control of concrete enterprises, and ensure that the process requiring continuous concrete pouring can be carried out normally from the source. Local construction administrative departments should urge the construction site to take effective measures to realize "six hundred percent" of enclosure around the construction site, stacking and covering of dust-prone materials, wet earthwork excavation, road hardening, cleaning of vehicles entering and leaving, and closed transportation of muck vehicles, and install online monitoring and video monitoring equipment.

(two) rotating consultation, strengthen cooperation.The Provincial Department of Housing and Urban-Rural Development and the Provincial Department of Ecology and Environment have established a monthly rotating consultation mechanism to regularly communicate, exchange work information and study intersection issues. Departments of city construction, urban management and ecological environment can refer to this model, regularly strengthen research on issues of common concern and concern, and formulate scientific, reasonable and effective emergency control measures for heavy polluted weather while doing a good job in dust control at the construction site, so as to prevent frequent shutdown of the construction process and bring greater risks to safety production. Local construction administrative departments should master the management of construction sites during emergency control, assess the impact of heavily polluted weather on engineering construction, and report to the Provincial Department of Housing and Urban-Rural Development in a timely manner.

(3) Strengthen joint law enforcement and implement precise punishment.Local construction, ecological environment and urban management departments should make full use of the provincial comprehensive monitoring platform for pollution prevention and control, weave and compile the "tight encirclement" for monitoring environmental pollution, integrate online monitoring facilities of construction, urban management, ecological environment and other departments, further strengthen information sharing, and implement online dynamic management of pollutant discharge. To carry out joint law enforcement actions on a regular basis, the construction administration of each district and city.The competent department shall put forward the "six hundred percent" implementation requirements (see the annex for the "six hundred percent" implementation reference suggestions)three) to provide a basis for the subsequent implementation of joint precision law enforcement.The outstanding and difficult problems found in the inspection are entered into the comprehensive supervision platform, and the whole process is tracked and supervised to ensure timely rectification. Local construction administrative departments should increase the frequency of inspections during the emergency control of heavy polluted weather, and immediately order rectification if they find that illegal construction and dust control measures are not in place; It is necessary to urge construction units to strengthen dust prevention and control education; For construction sites that have not stopped or resumed work without authorization, severe punishment methods such as fines, notification, credit scoring, and restrictions on market access should be adopted to force the construction unit to implement the responsibility of dust prevention and control.

(4) Improve the positive incentive mechanism and implement differentiated management.Exemption policy is an important mechanism to encourage the development of environmental protection. Local construction administrative departments should urge construction enterprises and construction sites to strengthen pollution control, improve the pollution control level against industry benchmarks, and meet the conditions stipulated in the Administrative Measures for Exemption of Production Stop and Production Limit in Autumn and Winter in Jiangsu Province and Supplementary Notice on Strengthening Exemption Management of Production Stop and Production Limit in Autumn and Winter in Jiangsu Province, and encourage enterprises and project departments to actively submit exemption applications to local housing and construction departments. The construction department should take the lead in dynamic management of the exemption list of emergency management and control, include the qualified ones in the exemption list of emergency management and control, ensure that the incentive policies are put in place, and strengthen the clear orientation of "doing well is different from doing badly" in environmental protection. During the emergency exemption period, if any behavior contrary to the exemption conditions is found, the exemption qualification will be cancelled, and no application can be made again within six months. If the circumstances are serious, the relevant acts shall be carried out in accordance with the provisions of the housing construction credit score.

Coverage requirements, methods and scope

　

I. Coverage requirements

Construction sites should strengthen management measures such as sealed storage or covering of cement and other fine-grained building materials that are easy to fly.Strengthen the coverage of exposed ground, material storage yard and shutdown site. Dust prevention measures such as dust prevention net covering and vegetation planting can be adopted for all kinds of exposed ground, mound and foundation pit excavation. Dust prevention net covering or vegetation planting should be adopted for vacant areas according to the service period and function. When building materials such as sand and stone and construction waste are piled in the open air, dust prevention net should be used for covering. For temporary construction, the exposed area and time of earthwork should be reduced as much as possible.

Second, the way of coverage

Dust-proof coverage in the construction area can adopt single coverage or composite coverage. Single coverage refers to the coverage method of using only dust-proof net, and the density of dust-proof net should be as dense as possible, and the dust-proof net with flat wire of more than four needles should be used for coverage to achieve the effect of dust prevention and dust fixation. By planting vegetation, before the greening effect is achieved, the dust-proof net should be used to cover it separately to form a composite cover, so as to achieve the effect of dust prevention and dust suppression. The dust-proof covering net in the construction area must be compacted firmly, which can play a good wind-proof and dust-proof effect in a certain period of time.

III. Coverage

In view of the shallow groundwater level in some areas of our province, the soil is sticky, the water retention is good, and the excavation is mostly wet soil, which is not easy to produce dust. In addition, the muck is generally covered with dense mesh, and the material is easy to age, the recovery rate is low, it is non-degradable, and it is easy to produce secondary pollution. Therefore, the covering requirements for the following procedures in the construction site are defined.

1. Requirements for muck covering in pile foundation engineering

Radius and periphery of working face of pile driver10-15mScope of the site, can not cover; The site should be paved with temporary roads, and the roads should be kept clean.

2. Requirements for muck coverage of foundation pit (trench) engineering

In the process of foundation pit (trench) excavation, the bottom of foundation pit may not be covered; If the foundation pit (groove) is sloping, the slope may not be covered; Parts involved in safety observation may not be covered; Hardened channels should be laid on the upper and lower ramps of the foundation pit, and the channels should be kept clean without covering the ramps; The wet muck can be stored in the shield tunnel section and the soil pit of the mining method tunnel without covering.

3. Requirements for muck coverage of municipal road engineering

Filler soil, waste soil and lime soil piled on site shall be covered; Earthwork or lime-soil subgrade shop48After hours, it has not been compacted, or the surface layer is dry and loose with dust after compaction, which should be covered; Water-stable inorganic binder base, after compaction, the surface layer is dry, loose and dusty, which should be covered; Effective dust prevention measures should be taken when dust-prone operations such as lime-soil mixing, pavement unification, cutting and chiseling are carried out.

4. Requirements for muck coverage of earthwork backfilling and greening in the later period.

Radius and periphery of mechanical working surface10-15mScope of the site, can not cover; After stopping the operation or after the completion of the operation, it should be in48Covering in time within hours.

5. Coverage requirements along the ground of high-speed rail or subway

In the construction site near the high-voltage catenary of high-speed rail or subway, the dust-proof net may be moved by typhoon, tornado and other forces, which may affect the safety of the high-voltage catenary. It is not appropriate to cover it with dust prevention net (refer to the relevant regulations of railway and subway protection zones for the safety distance), and it is appropriate to plant vegetation to achieve the effect of greening and solid settlement.

"Six hundred percent" implementation reference suggestions

　

First, the enclosure around the construction site is closed

oneConstruction sites in urban areas and built-up areas should choose enclosure types according to engineering characteristics to ensure enclosure tightness. Time limit exceededsixA month and don’t need to change frequently, should adopt a fixed enclosure with a closed bottom; Time limit for a project issixTemporary enclosures such as water yards can be used for those less than a month or those that need to be changed frequently on site.

2. Before the demolition, the demolition part shall be closed and fenced at the expropriation site where the household relocation is completed.

Second, the material stacking cover

one．Set up a special stacking area for easy-to-dust materials, so as to take them as you use them and cover them as you use them.

2Set up temporary garbage storage yard reasonably, and pile up construction garbage in a centralized and classified way.24If it cannot be removed in time within hours, dust prevention measures such as 100% coverage and sprinkling water shall be taken.

threeWet soil may not be covered, and the dried soil shall be cleaned, transported, turned over or covered in time. About wet soil (moisture content>5%) can be confirmed by observing that there is no obvious dust on the surface, squeezing free water or being able to twist and shape.

Three, earthwork excavation wet operation

oneDuring earthwork excavation, sufficient fog gun dust suppression equipment should be equipped, and the road should be cleaned, but water and ice should be prevented from causing potential safety hazards.

2For wet soil that does not produce dust, water spraying or spraying is not required. The specific judgment method is the same as above.

Fourth, pavement hardening

oneTemporary hardened pavement on the construction site shall be cast-in-place concrete or prefabricated panels that can be recycled.

2In the foundation construction stage, it is suggested to use temporary steel plates with satisfactory rigidity to harden the pavement, but it should be ensured that the temporary roads do not slip, dislocate or be damaged in use, and should be replaced in time after being damaged.

Five, in and out of the vehicle cleaning

one. All the body and wheels of engineering vehicles leaving the construction site should be cleaned, and equipped with automatic washing facilities. Only after washing can they enter the social road.

2Use information technology to strengthen supervision. For the construction site where the site conditions permit, it should be required to be equipped with vehicle unwashed capture equipment or video surveillance, and the relevant data should be pushed to the regulatory authorities with law enforcement power.

Six, muck vehicles closed transportation

Accelerate the upgrading of muck transport vehicles, and gradually force the use of closed muck transport vehicles (recommendedPvcFlat-push sealing mode) to solve the problems of vehicle overload, spilling and dripping.
