Environmental protection and dust control measures?

(1) Construction noise control measures

During the construction process, noise that disturbs residents should be minimized, and noise-prone steel processing, concrete vibrating rods, formwork removal, and backup generators should be etc., take the following measures to reduce or attenuate noise sources:

1. The construction site must be constructed in a civilized manner, establish and improve a management system to control man-made noise, educate all employees not to make loud noises at the construction site, and strengthen the awareness of all construction personnel Conscious awareness of preventing noise nuisance to the people.

2. Strictly control the operation time. The construction operation time should be controlled between 6:00 and 22:00 as much as possible, especially between 12:00 noon and 2:00 pm and after 10:00 pm. Surrounding residents must not be disturbed. rest. If continuous construction is indeed required due to process requirements or technical requirements, a night construction permit should be obtained and public notices should be made.

3. Closed noise-reducing sheds should be installed for high-noise machinery at the construction site to reduce the spread of strong noise. Noise limits must meet the provisions of "Noise Limits at Construction Site Boundaries (GB12523-90)".

4. Arrange the steel bar processing site away from the dormitory area, and try to carry out processing during the day.

5. The concrete vibrator should be informed to the operator to avoid contact with the formwork and steel bars as much as possible.

6. To direct production at the construction site, use radio walkie-talkies for work communication, which can reduce artificial shouting at the site.

7. Strengthen the management of the entry and exit of on-site transportation vehicles. Vehicles are prohibited from honking their horns when entering the site. Manual delivery is used for loading and unloading of steel pipes and formwork to reduce the impact of metal parts. This will keep the environment at the construction site as quiet as possible.

8. When earthwork is excavated and transported at night, drivers should be educated on environmental protection. No noise is allowed and whistles are prohibited. The excavator should be loaded lightly and slowly to reduce the sound of bulk materials rushing out of the carriage.

(2) Construction disturbance control measures

The buildings (structures) adjacent to the project, surrounding roads, etc. should be carefully checked and recorded first, and measures may be taken to prevent any harm caused by them. Reinforce preventive measures.

Posting notices to protect residents around the construction site has received support and understanding from nearby residents.

(3) Water pollution control measures

1. Wastewater washed from vehicles entering and leaving the site is discharged into the sedimentation tank. The mud and mortar slurry can be clarified through secondary sedimentation before it can be discharged into the sedimentation tank. Within the municipal drainage network.

2. The toilet is equipped with flushing facilities, and the sewage discharged from the toilet is discharged into the septic tank. After being treated in the septic tank, it is discharged into the municipal drainage pipe network.

3. A grease trap is set up in the temporary canteen at the construction site. The generated sewage is first treated through the grease trap and then discharged into the municipal drainage pipe network. Management should be strengthened and oil should be removed regularly to prevent pollution.

4. Set up continuous rainwater drainage facilities on site to ensure organized drainage of rainwater on site. 5. It is prohibited to use hazardous waste as earthwork backfill to avoid contaminating groundwater and the environment.

6. The floor sewage is discharged from the upper floor to the sedimentation tank in an organized manner using PVC pipes. After secondary sedimentation, it is then discharged into the municipal drainage pipe network.

(4) Dust control measures

1. Carefully manage the general construction plane. Dedicated management is adopted around the construction site. In order to keep the site tidy, water is sprayed and cleaned 2-3 times a day, and the flowers, plants and trees in the green area are regularly sprayed with water to wash away dust.

2. The construction site implements closed management and encirclement operations. Starting from the main construction, a dust-proof dense mesh safety net is erected from the periphery of the bottom floor of the building, and the closed height is more than 1.2 meters higher than the construction work surface.

3. Set up dedicated personnel to clear and transport construction waste, conduct civilized construction on site, and promptly clean each floor after construction. When cleaning, sprinkle water first, moisten and then remove and clean. The cleaned garbage should be piled in within the specified container.

4. Consolidate and seal construction waste and other waste into a covered bucket, lift it to the ground with a centralized machine, handle and clear it in a timely manner, and do not throw construction waste from high altitudes to prevent dust from flying. .

5. Vehicles transporting sand, cement, earthwork and construction waste must be covered and must not be scattered along the streets or roads. Vehicles leaving the construction site are required to flush their tires with water, and the roads entering and exiting the site must be paved with straw mats to reduce mud and soil contamination of the site road and street pavement, and to avoid causing soil and dust to scatter. At the same time, dedicated personnel will be assigned to cooperate with cleaning to ensure that the city appearance and surrounding environment are clean. Do not take soil, dust, etc. out of the construction site.

6. Fine-grained bulk materials that are easy to fly should be stored in the warehouse as much as possible. If they need to be stored in the open air, they should be covered tightly to avoid causing soil and dust to scatter. At the same time, dedicated personnel will be assigned to cooperate with cleaning to ensure the cleanliness of the city and surrounding environment. Temporary piles of soil must be covered and watered and dusted by dedicated personnel, and exposed soil must be solidified or greened.
