Is the noise at the boundary of the construction site tested the new standard or the old standard?

The 2011 standard will not be implemented until June 1, and the old standard is still in force. At the time of the exam, the standard had not yet been implemented.

Of course, the new standard is a little ahead of the textbook, what's wrong? Do you expect to change this part of the textbook again next year?

However, the new standard has been announced, and the requirements in the outline feel that they are required according to the new standard.

Judging from the content of the syllabus, I personally feel that it is required according to the new standards.

Hello, I am glad to serve you and give you the following answers: The latest standard of "Noise Limits at the Boundary of Building Construction Sites" is the "Technical Specification for Noise Control at the Boundary of Construction Sites" (GB50325-2010), which stipulates the noise limits at the boundary of construction sites, that is, during the day (7:00-22:

00) The maximum noise of the mask should not exceed 75 decibels, and the maximum noise at night (22:00-7:00) should not exceed 70 decibels.

In order to solve the noise problem at the boundary of the construction site, we must first do a good job in noise source control, that is, take technical measures to improve the structure of machinery and equipment and reduce the emission of noise sources; Secondly, noise control measures should be taken, that is, technical measures such as shielding, absorbing and muffling should be taken to reduce the spread of noise; Finally, environmental control measures should be taken, that is, environmental improvement measures should be taken to improve environmental conditions and reduce the spread of noise. The above is a brief introduction to the latest standards and solutions and practices for noise limits at the boundary of building construction sites, hoping to help the big rock bridge potato family.

If the construction noise is discharged to the surrounding living environment within the urban area of the city, it shall meet the environmental noise emission standards for the construction site boundary stipulated by the state: 70dB (a) during the day and 55dB (a) at night; The maximum noise level at night shall not exceed the limit by 15dB (a).

Building construction refers to the production activities in the implementation stage of engineering construction, and is the construction process of various buildings, including foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc., except for the interior decoration activities of residential buildings that have been completed and delivered.

According to the Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution, the environmental noise at the boundary of the site during the construction process shall not exceed 70db(a) during the daytime; It must not exceed 55dB (a) at night. The maximum noise level at night shall not exceed the limit by 15dB (a).

There are also relevant regulations for noise during the specific construction phase of the construction site.

1. In the earthwork construction stage, the main noise sources are bulldozers, excavators, etc., and the noise limit is 75db (a) during the day and 55db (a) at night.

2. The main noise source in the piling construction stage is all kinds of pile drivers, etc., and the noise limit is 85db (a) during the day, and construction is prohibited at night.

3. In the construction stage of the structure, the main noise sources are vibrating rods, chainsaws, etc., and the noise limit is 70db (a) during the day and 55db (a) at night.

4. In the decoration construction stage, the main noise sources are cranes, elevators, etc., and the noise limit is 65db (a) during the day and 55db (a) at night.

Construction noise: refers to the sound generated during the construction process that interferes with the surrounding living environment.

According to the provisions of relevant laws and regulations, the prevention and control of noise pollution in construction involves the following aspects:

First, if construction noise is discharged into the surrounding living environment within the urban area of the city, it shall comply with the environmental noise emission standards for the boundary of the construction site stipulated by the state.

Second, within the urban area of the city, the use of machinery and equipment in the construction process may produce environmental noise pollution, the construction unit must be reported to the local people's environmental protection administrative department at or above the county level where the project is located 15 days before the start of the project, the construction site and the deadline, the environmental noise value that may be generated and the environmental noise pollution prevention and control measures taken. If the report is refused or falsely reported, the local people's ** environmental protection administrative department at or above the county level shall give a warning or impose a fine according to the circumstances.

Third, in the urban areas where noise-sensitive buildings are concentrated, that is, medical areas, cultural, educational and scientific research areas, and areas dominated by institutions or residential buildings, it is forbidden to carry out construction operations that produce environmental noise pollution at night, except for emergency repairs, emergency operations and continuous operations that must be carried out due to production process requirements or special needs. "Night" means between 22 p.m. and 6 a.m. If it is indeed necessary to operate continuously due to special needs, it must be certified by the people at or above the county level ** or its competent department, and the nearby residents must be announced.

Laws and regulations: Article 28 of the Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution stipulates that the emission of construction noise to the surrounding living environment within the urban area of the city shall comply with the environmental noise emission standards for the boundary of the construction site stipulated by the state.

Article 29 stipulates: within the urban area of the city, the use of machinery and equipment in the construction process, may produce environmental noise pollution, the construction unit must be 15 days before the start of the project to the local people's environmental protection administrative department at or above the county level where the project is located to declare the project name, construction site and period, possible environmental noise value and prevention and control measures. Article 30 of the Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution stipulates:

In areas where noise-sensitive buildings are concentrated in urban areas, it is forbidden to carry out construction operations that produce environmental noise pollution at night.

Generally refers to going from 10 a.m. to 6 a.m. in the evening.

Legal Analysis: The noise limit standard at the boundary of the building construction site stipulates (1) The daytime construction is not allowed to exceed 75db in the earthwork construction stage, and the night construction is not allowed to exceed 55db. (2) In the piling construction stage, the construction during the day is not allowed to exceed 85db, and the construction is prohibited at night.

3) In the structural construction stage, the daytime construction is not allowed to exceed 70db, and the night construction is not allowed to exceed 55db.

Legal basis: Civil Procedure Law of the People's Republic of China

Article 76: Parties may apply to the people's court for an evaluation on specialized issues of ascertaining facts. Where the parties apply for an appraisal, the parties are to negotiate to determine a qualified evaluator; and where negotiation fails, the people's court is to appoint one. Where the parties have not applied for an evaluation, and the people's court finds that an evaluation is necessary for a specialized issue, it shall retain a qualified evaluator to conduct the evaluation.

Article 77: Evaluators have the right to learn about the case materials needed to conduct evaluations, and when necessary, may question parties and witnesses. The evaluator shall submit a written evaluation opinion and sign or affix a seal to the appraisal document.

Article 78: Where parties have objections to an evaluation opinion or the people's court finds that it is necessary for an evaluator to appear in court, the evaluator shall appear in court to testify. Where upon notice from the people's court, the evaluator refuses to appear in court to testify, the evaluation opinion must not be the basis for determining the facts; The party who paid the appraisal fee may request a refund of the appraisal fee.

Article 79: Parties may apply to the people's court to notify persons with specialized knowledge to appear in court and submit opinions on evaluation opinions or professional issues made by evaluators.

Article 80: In the inquest of physical evidence or at the scene, the inquest person must present the people's court's identification, and invite the local basic-level organization or the party's unit to send someone to participate. The parties or their adult family members shall be present, and where they refuse to appear, it does not impact the conduct of the inquest. Relevant units and individuals have the obligation to protect the scene and assist in the inquest work on the basis of the notice of the people's court.

The inquest personnel shall make a record of the circumstances and results of the inquest, and the inquest personnel, the parties, and the invited participants shall sign or affix a seal.

Legal analysis: Depending on the region, the standard varies, and the construction site is 70 decibels.

Legal basis: Article 58 of the Public Security Administration Punishment Law of the People's Republic of China: Anyone who violates the laws and regulations on the prevention and control of noise pollution in social life and creates noise that interferes with the normal life of others shall be given a warning; and where corrections are not made after warning, a fine of between 200 and 500 RMB is to be imposed.

Article 5 of the Environmental Quality Standards for Voice Actors: According to the characteristics of the use function and environmental quality requirements of the region, the sound environment function is divided into the following five types:

Acoustic environment functional area: refers to the ** recuperation area and other areas that need to be quiet.

Acoustic environment functional area: refers to the area with residential, medical and health, culture and education, scientific research and design, and administrative office as the main functions, and needs to be kept quiet.

Acoustic environment functional area: refers to the area with commercial finance and bazaar as the main function, or residential, commercial and industrial mixing, and the need to maintain residential quiet.

Acoustic environment functional area: refers to the area with industrial production, warehousing and logistics as the main functions, and it is necessary to prevent industrial noise from having a serious impact on the surrounding environment.

Acoustic environment functional area: refers to the area within a certain distance on both sides of the traffic artery that needs to prevent traffic noise from having a serious impact on the surrounding environment, including two types: Class 4A and Class 4B.
