A, earthwork environmental protection measures
(1) Environmental protection measures when using construction machinery
1. When using bulldozers, loaders, excavators, graders, road rollers, rammers and other construction machinery, attention should be paid to the emission of dust and tail gas so as not to pollute the atmosphere.
2. Pay attention to whether the mechanical oil tank is leaking, leaking, dripping or leaking, so as to avoid soil pollution caused by flowing into the soil.
3. The amount of mechanical noise should be controlled within the scope of avoiding noise pollution to the community.
4. Mechanical oil should be used less to save energy.
5. Save water and water resources when washing mechanically.
6. The flushing water of oily machinery should be discharged reasonably to avoid polluting municipal pipelines.
7. Oily cotton yarn and gloves should be disposed of and thrown into the garbage to avoid soil pollution.
(2) Environmental protection measures for earthwork transportation, muck piling and disposal.
1. Dregs should be classified, which is beneficial to garbage disposal. Dregs should be buried in deep pits to save land resources.
2. Useful solid waste in muck should be recycled to save resources and reduce pollution.
Harmful dregs should be treated and discharged to avoid polluting soil and community.
4. Pay attention to dust emission when removing muck, so as not to pollute the atmosphere.
5. The earth truck comes out from the soil source to tamp, reshape and cover the loose soil; The site dump site is covered with green dense mesh safety net.
When earthwork is transported abroad, attention should be paid to avoid the pollution of pavement and atmosphere caused by scattering and dust. Sprinklers will be arranged on the construction road to sprinkle water to reduce dust every day. Pay attention to the problems of soil and dregs during transportation, so as not to affect the pollution of the city.
(3) Environmental protection measures during the operation of construction machinery
1. In order to avoid the influence of heavy machinery on the surrounding residents and prevent the surrounding buildings from being cracked by earthquake, a quakeproof trench is dug between subgrade, residential area and buildings while using large-tonnage compaction machinery for static pressure.
2. According to the Hygienic Standard for Noise in Industrial Enterprises, workers should take turns to operate road construction machinery to reduce the time of exposure to high noise, or alternately arrange high noise and low noise work. For the construction personnel close to the noise source, in addition to taking labor protection measures such as wearing protective earplugs or helmets, their working hours should be shortened appropriately.
3. In order to ensure that the residents of the construction site have a rest at night, the construction of the construction site within the residential area 150m will be stopped from 22: 00 to 6: 00 at night.
Second, the construction site environmental protection measures
(a) construction waste removal at any time, it is strictly prohibited to volley throw at will, and sprinkle water every day to dust.
(2) Fine-grained materials that are easy to float in the sky, such as cement, should be stored in the warehouse or covered, and scattered flying should be prevented during transportation, and dust suppression measures should be taken during unloading.
(3) The construction pavement shall be cleaned once a day and watered three times. The pavement should be hardened in combination with the permanent road layout in the design, and a car washing place should be set up. Cleaning production garbage should effectively prevent secondary dust. Sprinkling water and washing the car should be moderate, so as not to cause waste.
(four) the exhaust emissions of various transport vehicles must meet the relevant national standards, and vehicles exceeding the standard are prohibited from driving on the road.
(five) make full use of open space to do a good job of greening and beautifying the environment.
