A continuous and airtight brick wall is set around the construction site.

Around the construction site, it is continuously closed, and the solid wall is built with bricks, which is durable, safe and reliable; In case of weak geology, the foundation of concrete pouring reinforced keel should be laid.

The height of the fence is 2.5m, and 1 constructional column is set every 6m.

Encourage innovation: 1. Encourage the construction of reinforced concrete precast walls on housing sites, and the brick masonry retaining wall at the bottom of the wall is completely sealed.

2. Encourage the construction of durable, solid, reliable, beautiful and generous walls where houses are located. The brick retaining wall at the bottom of the wall is completely sealed.

3. Encourage construction sites to build temporary construction fences into permanent transparent fences to realize "temporary-permanent integration". The brick retaining wall at the bottom of the fence is completely sealed.

4. Encourage housing construction sites to explore the construction of a densely planted "green vegetation" belt with a height of 3 meters and a thickness of 0.6 meters, and install a hard steel mesh with a height of 2.5 meters in the middle of the vegetation.
