What are the prevention and control measures for dust pollution at construction sites?

1. Construction site fence

The fence of this project is fully enclosed, using stereotyped materials and turf decoration, which highly meets the requirements. The advertisements on the fence are mainly public service advertisements. Made of pvc material. The content and quantity of public service advertisements meet the requirements and are clean and beautiful.

2. The outer scaffolding frame is closed

The outer scaffolding frame is sealed with a dense mesh safety net along the inside of the outer frame. The safety nets are firmly connected, tightly sealed, and connected with The frame is fixed. The bottom ceiling of the cantilever frame is fully enclosed, safe and beautiful.

3. Hardening of the main roads and sites at the construction site

The entrances and exits of the construction site, main roads in the site, material storage sites and processing sites are hardened with concrete and other materials. The site drainage is smooth and there is no obvious Standing water. The hardened area of ??the project's main roads, material storage sites and processing plants reaches 9,000 square meters.

4. Covering exposed earthwork and bulk materials

Fine-grain building materials that easily generate dust (cement, fly ash, lime soil, fine sand and gravel, etc.) are stored in a closed store or covered. The mortar bucket is made of stereotyped materials and can be hoisted and reused. The top is fully enclosed and the bottom is closed in time with a sliding door to control dust.

5. Cleaning of transport vehicles before exit

Set up automatic vehicle flushing devices at the entrance and exit of the construction site and ensure 100% use. Clean the vehicles when exiting to ensure clean vehicles exit. This project adopts an intelligent construction site dust management and control system.

It is also connected to the Tonglu County dust control system platform to promote the construction of "smart dust prevention". A sedimentation tank is provided at the construction site, and only sewage that meets the requirements can be discharged into municipal sewage pipes after sedimentation. This project has obtained a sewage discharge and drainage permit.

6. Take measures to reduce dust by sprinkling water at the construction site

Equip a sprinkler truck at the construction site, establish a water-sprinkling cleaning and dust reduction system and strictly implement it. During the foundation earthwork construction stage, equipment such as mobile dust suppression fog cannons, high-pressure dust suppression water cannons, and sprinkler linkage systems are actively used to control dust. The sprinkler systems mainly use external frame sprays, site sprays, etc.

7. Install dust online monitoring facilities

This project *** installs two dust online monitoring facilities***, both of which are connected to the Hangzhou dust online monitoring data platform and maintain Online, dust warning, alarm and other functions can be realized.

8. Measures for garbage transportation and storage at the construction site

Set garbage storage points at the construction site and strictly implement the garbage classification system. The construction waste in the building shall be removed and transported in a timely manner by means of closed container transport, trolley transport, etc. Appropriate watering and other measures shall be taken during the removal to reduce dust.
