The production, installation and use of temporary fences for foundation pits have very strict specifications. Today we will take a look at the installation process of temporary fences for foundation pits.

The installation process of the temporary fence of the foundation pit is roughly divided into the following steps:

Measure pay-off, original ground treatment (refilling and tamping), along-slope and excavation of foundation pits, temporary positioning of pillars, installation of fence mesh, pouring of column concrete foundation, overall fastening and adjustment of fence mesh.

1. Survey lofting: carry out construction lofting according to the design requirements of the drawings and the actual topography and features, determine the centerline of the column, and install the fence net according to the specified slope and line shape.

2. The original ground treatment is an important prerequisite to ensure that the installation of the protective fence is smooth and overall firm. The weak layer under the foundation must be replaced and tamped before the column can be buried to ensure the firmness of the column. The column installation is carried out in sections. From the longitudinal perspective, the axis of the column should be in a straight line, and there should be no unevenness; from the height, the top of the column should be smooth, and there should be no unevenness, except for special terrain.

3. Set up benchmarks and white lines according to the measurement stakeout, fill and excavate and slope down the original surface, and compact it again, install the stakeout location and excavate the foundation pit to ensure the size of the foundation pit.

4. During the column installation process, the column must be stable and tightly connected to the foundation. During the column installation process, a small line should be used to detect the straightness of the column installation, and local adjustments should be made to ensure that the straight line section is straight and the curve section is smooth The column is fixed in accordance with the design drawings.

5. The mesh of the temporary fence must be firmly connected to the upright post, and the surface of the mesh should be installed flat without obvious warping and unevenness.

6. After temporary positioning and installation of the temporary fence post, install the fence piece. After ensuring that the installation is correct and firm, pour the concrete foundation and maintain it in time.
