Common safety problems of construction enclosure customization

Common safety problems in the customization of construction enclosures

In the setting and installation of enclosures, some construction units think that the enclosures at the construction site are temporary The setting should be paid attention to, and the construction should not be carried out in accordance with the requirements of the specification; secondly, in order to save materials, the fence is built with clay, so that the bricks of the fence can be removed for secondary use after the project is completed, but this approach will inevitably cause the fence itself to have too low strength and poor stability; three The fence was built near the edge of the forest belt and green vegetation. No preventive measures were taken during the construction. Due to the frequent watering of the forest belt and the influence of green micro-spray, the foundation of the fence continued to sink, the wall skin fell off, and the wall was tilted. Collapse; Fourth, a large amount of soil, sand and gravel or other building materials are piled up on one side of the fence at the construction site, which produces a large lateral pressure on the fence, which leads to the collapse of the fence.

1. When building a fence on the original ground, the depth of foundation excavation should not be less than 400mm. The construction sequence is: municipal fence manufacturer First, use M5 cement mortar to build two layers of 500-wide brick foundation and build a layer of 370-layer 500-high 240-wide solid brick masonry M1 clay mortar to build 240 empty bucket walls M5 cement mortar enclosure wall to press the roof to construct the enclosure custom.

2. On soft ground, when masonry walls are built, the depth of foundation excavation should not be less than 500mm. The construction sequence is: ram the bottom of the foundation trench for M5 cement mortar masonry. Build four layers of 500 wide brick foundation, build a layer of 370 bricks, build 1000mm high 240 solid brick masonry M1 clay mortar, build 240 empty bucket walls and M5 cement mortar to press the roof.

3. When building fences at the edge of the forest belt and vegetation, the influence of watering of the forest belt and greening micro-spray should be considered first, and the foundation depth should not be less than 600mm. The construction sequence is as follows: : First pour 500 wide and 200 mm thick C10 concrete M5 cement mortar to build a 100 mm high 240 solid wall M1 clay mortar to build a 240 empty bucket wall M5 cement mortar to press the top, and the wall near the forest belt and vegetation side is completed immediately. Use M5 waterproof mortar to plaster the surface to construct the enclosure customization.

4. When building the fence, the spacing of the brick stacks should be set according to the specification requirements, generally 3~3.6m to set up a brick stack; When the empty bucket wall is to be built, it should be built in accordance with the 'five buckets and one sleep' to ensure the overall stability of the enclosure wall.
