How high is the safety fence at the construction site?

A closed enclosure with a height of not less than 2.5 meters shall be set on the main sections of the urban area; A closed enclosure with a height of not less than 1.8m should be set in general sections. The enclosure should be firm, stable, neat and beautiful, and the enclosure wall should publish public service advertisements and publicity slogans for quality, safety and civilized construction. The fence is equipped with a spray dust suppression system.

The safety and civilized construction of the extended information construction site is as follows:

1. Gate: Gate should be set at the main entrance and exit of the construction site, and an information real-name management system for face recognition and workers' information sharing should be installed; The color of the gate is in harmony with the surrounding environment; The size of the gate can be determined according to the actual situation, but it should meet the requirements of vehicle and personnel traffic and fire fighting; The portal frame structure is made of suitable materials to ensure firmness and durability.

2. Site enclosure: Enclosures should be set around the construction site of the project under construction, which should be firm, stable, neat and beautiful, and closed enclosures with a height of not less than 2.5 meters should be set on the main sections of the urban area; A closed enclosure with a height of not less than 1.8m should be set in general sections. Public service advertisements and propaganda slogans of quality, safety and civilized construction should be published on the enclosure wall. The fence is equipped with a spray dust suppression system.

3. Monitoring system: For newly-started housing construction projects with a contract price of 50 million yuan or more, a video monitoring system must be installed at the construction site, and at least 1 high-definition spherical camera with zoom and night vision function should be installed at the entrance and exit of transportation vehicles on the construction site, which is required to cover the entrance and exit of the construction site, water tanks and roads within 30 meters on both sides of the project. The video surveillance system shall share information with the departments of construction and administrative law enforcement.

4. Car washing platform and sedimentation tank: Car washing platform (tank), sedimentation tank and automatic car washing facilities are set at the entrance and exit of transport vehicles. The car washing platform (pool) is provided with a drainage ditch to a sedimentation tank. Car washing platform (tank) must have a good drainage system, with drainage ditches around it. Car washing platform (pool) should be equipped with concrete sedimentation tank to ensure smooth drainage and prevent random discharge. Ensure that transport vehicles must be taken out of the mud and cleaned before leaving the site.

5. Construction garbage disposal: The construction garbage and domestic garbage on the construction site should be stored in a closed garbage station. It is forbidden to throw into the air, and clean up in time. Burning garbage and other wastes is strictly prohibited on the construction site. Construction earthwork, muck and construction waste shall be transported by closed transport vehicles, and driven according to the designated transport route and time, and dumped to the disposal site that meets the requirements. It is forbidden to "drip" and dump.

6. Site hardening: the main entrances and exits, main roads, material processing areas, stacking areas, living areas and office areas of the construction site shall be ground hardened according to regulations. The main road of construction should be determined according to the needs of the project, and the exit section should be extended to connect with the municipal roads outside the construction site. The specific practices of the main construction roads shall be determined by the construction unit according to the actual situation.

7. Scaffolding: A dense mesh safety net should be set on the outside of the scaffold for sealing and hanging tightly, and a spray dust suppression system should be set on the outside of the scaffold.

8. Isolation and enclosure of the work area: The building materials, components and materials on the construction site should be classified and stacked neatly according to the general layout and fenced; The material storage yard should be hardened and the drainage should be smooth. Flammable, explosive, toxic and harmful articles should be stored separately.

9. Application of BIM technology: Building information model (BIM) technology must be applied to the construction site of prefabricated buildings.
