Noise pollution is a common problem in urban construction. Engineering noise control is one of the important measures to ensure the normal life and health of urban residents. This article will introduce the decibel standards for engineering noise control and noise construction to help you understand how to reduce the impact of noise on the environment and human body.
1. Engineering noise control.
Engineering noise refers to the noise generated during the construction of construction projects, including the noise emitted by construction machinery, transport vehicles, pile drivers, concrete mixers and other equipment. These noises will not only affect the normal life of the surrounding residents, but also have a certain impact on their health. Therefore, engineering noise control is indispensable.
The main measures for engineering noise control include:
1.Reasonable planning of the construction site: Before construction, a detailed survey of the construction site should be carried out, the construction site should be reasonably planned, and noisy construction operations should be avoided in sensitive areas such as residential areas as much as possible.
2.Choose low-noise equipment: During the construction process, low-noise equipment should be selected, such as low-noise concrete mixers, low-noise excavators, etc., to reduce the impact of mechanical noise on the surrounding environment.
3.Strengthen equipment maintenance: For mechanical equipment, daily maintenance and maintenance should be strengthened to ensure the normal operation of the equipment, reduce the equipment failure rate, and reduce the noise caused by equipment failure.
4.Reasonable arrangement of construction time: During the construction process, the construction time should be reasonably arranged, and noisy construction operations should be avoided during sensitive periods such as night.
Second, the decibel standard of noise construction.
In order to better control engineering noise, China has formulated the corresponding noise construction decibel standard. According to the standard, the noise decibel standards for different construction stages are as follows:
1.Earthwork construction stage: no more than 75 decibels during the day and no more than 55 decibels at night.
2.Piling stage: no more than 85 dB during the day and no more than 65 dB at night.
3.Structural construction stage: no more than 70 decibels during the day and no more than 55 decibels at night.
4.Decoration construction stage: no more than 65 decibels during the day and 55 decibels at night.
These standards not only specify the upper limits of noise decibel at different construction stages, but also the corresponding measurement methods and measuring instruments. During the construction process, the noise at the construction site shall be monitored and controlled in accordance with the requirements of the standard to ensure that the construction noise does not exceed the specified decibel standard. If it is found that the standard provisions are exceeded, corresponding measures should be taken in time to deal with it.
3. Reduce the impact of noise on the environment and human body.
In addition to the decibel standards for engineering noise control and noise construction, we can also take the following measures to reduce the impact of noise on the environment and human body:
1.Strengthen publicity and education: Through publicity and education, raise the public's awareness and attention to noise pollution, so that the public can understand the hazards of noise and the importance of noise reduction.
2.Rational planning of urban layout: In urban planning, the urban layout should be rationally planned, and sensitive areas such as residential areas should be placed adjacent to noise pollution sources such as construction sites.
3.Promotion of low-noise building materials and technologies: Reduce the noise level inside buildings by promoting low-noise building materials and technologies, thereby reducing the impact on the lives of residents.
4.Strengthen personal protection: In daily life, we can also take some personal protective measures to reduce the impact of noise on the human body, such as using earplugs, headphones and other protective equipment to reduce the impact of noise on hearing.
In short, the decibel standard of engineering noise control and noise construction is one of the important measures to control engineering noise. We should strengthen publicity and education, rationally plan urban layout, promote low-noise building materials and technologies, and strengthen personal protection to reduce the impact of noise on the environment and human body.
