Reading tips. Recently, a construction project in Kunming, Yunnan Province, has been frequently complained about disturbing the people due to night construction. Relevant departments issued notices to refine the work requirements related to the prevention and control of noise pollution in night construction. The construction party said that it would optimize the process to reduce noise, and strive to take care of both work and rest.
In recent years, with the rapid development of urbanization, construction projects have emerged in an endless stream, and the consequent construction noise at night has also become a hot topic of concern to the public. The Ministry of Ecology and Environment recently released a report showing that the national acoustic environment functional zone reached the standard rate of 82 percent last Chinese New Year's Eve9%, which is 12 lower than the daytime compliance rate5 percentage points. Recently, a construction project in Kunming, Yunnan Province has also been frequently complained about because of the disturbance of night construction
Yunnan has comprehensively rectified the problem of noise disturbance from construction at night.
In July this year, the Ministry of Ecology and Environment made written and first-class scheduling on the handling of repeated complaints about the night construction of the Damingyuan construction project in the Dianchi Resort of Kunming City, Yunnan Province. The Kunming Municipal Bureau of Ecology and Environment investigated and dealt with the noise violations of the Damingyuan construction project in accordance with the law, and ordered the illegal acts to be corrected immediately.
During the reporter's visit, although the noise was not as loud as that night when the residents reported the problem, the night was dark, and there was silence all around, and the surrounding high-rise buildings formed a natural "echo wall", even if the shovel was dragged on the asphalt road, it had an echo. Standing in front of a residential building, the sound of construction makes people a little upset.
In order to effectively solve the problem of disturbing the people during the night construction of the Damingyuan construction project, the Yunnan Provincial Department of Ecology and Environment organized the Kunming Municipal Ecological Environment Bureau and other relevant municipal departments to conduct in-depth on-site field investigations, and jointly study measures with the construction unit and the construction unit, and work together to promote the implementation of rectification measures. Kunming City regards night construction noise disturbance as a prominent ecological and environmental problem, innovates work ideas, implements departmental responsibilities, and comprehensively strengthens rectification.
On November 21, the Kunming Municipal Department of Ecology and Environment, Housing and Urban-Rural Development, and Urban Management jointly issued the "Notice on Refining the Work Requirements for the Prevention and Control of Noise Pollution in Night Construction" to strengthen the approval and management of night construction sources and strictly control night construction in areas where noise-sensitive buildings are concentratedImplement staggered peak hours for construction vehicles to enter the city during the day to reduce noise pollution caused by the centralized transportation of muck and engineering transport vehicles at nightTo further implement the responsibility for noise pollution prevention and control, the competent departments of various industries shall urge the construction unit to include the noise pollution prevention and control cost in the project cost, clarify the responsibility of the construction unit in the construction contract, and formulate the implementation plan for noise pollution prevention and controlIllegal acts such as failure to carry out night construction filing, exceeding the filing time limit, and exceeding the scope of filing shall be strictly investigated and dealt with in accordance with the law.
The entry time is earlier, and the construction process is more ingenious."
Can a notice solve the problem of construction noise at night?
During the reporter's on-site investigation, it was found that some construction projects had to be carried out at night, and the problem often showed a high incidence trend in spring, autumn and winter. With the deepening of the investigation, the reporter found that some night construction can not be stopped, especially in the past two years, affected by the epidemic, some livelihood projects have been slowed down, if simply stopped, although the immediate disturbance problem has been alleviated, but the relationship between the people's livelihood problems has not been solved, and the impact is far-reaching.
The reporter visited the site and found that some construction sites in Kunming were equipped with first-class surveillance cameras to monitor the construction situation of the construction site in real time.
The rain and sewage diversion transformation project (bid section) in Xishan District, a key livelihood project in Kunming undertaken by Yunnan Branch of China Construction Third Engineering Bureau Southwest Company, has completed the rain and sewage diversion transformation in the community, and is currently accelerating the transformation of rain and sewage diversion of municipal roads.
Li Long, the project foreman, said that since the start of the second half of 2022, considering that the construction location is close to the concentration area of sensitive buildings, in order to minimize the impact of night construction on residents, the project team has carefully planned and adjusted the construction rhythm, and increased the investment in machinery and labor. For noisy processes, try to avoid rest periods, and use low-noise source equipment to cooperate with manual finishing work at night.
Before the start of night construction, our construction team will organize the people, materials and machines involved in the construction period to be on standby at the site in advance, prepare with sufficient resources to speed up the construction rhythm, shorten the night construction time, and at the same time, according to the actual construction site, divide the sensitive area of the construction operation, increase the height of the construction enclosure, install mobile sound insulation panels, use low-noise technology and facilities and equipment, and strive for understanding and support. Li Long said.
Let the construction entry time be earlier, and the construction process will be more skillful. Qiu Xuexi, director of the project materials of Yunnan Northeast Yunnan Medical Center of China Construction Fifth Bureau, said that after the completion of the project, it will greatly improve the medical level of Yunnan and eastern Yunnan. Optimize the construction deployment, use commercial concrete and commercial mortar for the construction site, reduce the noise of mixing and vibration, take isolation measures for concrete pump trucks, set up soundproof sheds when pouring concrete, and set up dust and noise monitors at the construction site, so that night construction does not disturb the people.
How do you find the right balance?
According to the staff of the Kunming Traffic Police Detachment, the traffic management department for the management of night construction, based on Article 32 of the Road Traffic Safety Law, which requires the occupation and excavation of roads due to the construction of the project, or the erection of crossings and crossing roads, and the addition of pipeline facilities. It is mentioned in the law that the construction operation unit shall carry out the construction work within the approved road section and time.
In the past two years, the traffic management department has taken into account the difficulties of some construction units, and has adopted the method of flexible approval of operation time, for the livelihood projects that can only be implemented at night, the traffic management department has flexible examination and approval, and appropriately adjusted the access time of the construction unit without affecting traffic safety.
At present, the construction period is scientifically adjusted for people's livelihood projects, and the "one policy" is to apply for the daytime entry pass for muck and transport vehicles for enterprises, and coordinate the construction unit of the special route for muck trucks to enter and exit the city to replace the transport vehicles with new energy trucks, so as to reduce the impact of vehicles on the surrounding residents during transportation.
As a construction unit, the person in charge of the Yunnan Company of China Construction Fifth Bureau said that if it can enter in advance, as a construction unit, it must compress the noisy process as far as possible, and complete the "road breaking" and other operations before the middle of the night to avoid sharp noise after 12 o'clock in the middle of the night. The construction unit will continue to optimize the construction process and continue to reduce the volume in the process of paving and removing iron plates. At the same time, the transport vehicles will be replaced with new energy trucks to reduce the impact of vehicles on the surrounding residents during the transportation process, and the surrounding residents will be visited in advance to inform the noise reduction measures taken to strive for understanding and support.
Kunming Anning City Management staff proposed that in addition to the construction level, there should also be better methods in the work of the masses. After all parties understood the benefits of this livelihood project, the community said that it would explain to the residents in more depth and coordinate all parties to find a balance. (Worker**).
