Precautions for installation of double wire fence:
1. When the mesh and column used in the double-ring fence are transported to the construction site, the construction unit must provide the supervision engineer with a product qualification certificate. Supervision engineers have the right to test and inspect meshes and columns with project quality problems.
The engineering supervision engineer shall check the curvature of the uprights on site, and clear out those with obvious deformation, curling, or scratches.
2. When carrying out the concrete foundation construction of the guardrail column, the construction unit should release the foundation center line in accordance with the approved construction organization TRANBBS design and design drawings, and carry out the necessary leveling and cleaning of the site to ensure
After the isolation barrier is installed, the line shape is beautiful and straight. Before the foundation concrete is poured, the size of the foundation pit and the distance between the foundation pits must be inspected and approved by the supervision engineer before the concrete can be poured.
3. During the installation process of the column, the stability of the column must be ensured, and the close connection with the foundation must be ensured. If necessary, supports can be installed to stabilize the column. During the installation of the column, a small line is used to detect the straightness of the column installation, and the local
Line adjustment. Make sure the straight section is straight and the curved section is smooth. The buried depth of the column shall meet the requirements of the design drawings. After the construction of the column is completed, the supervision engineer shall inspect the line shape, buried depth, and height of the column, and improve the stability of the connection with the foundation.
Line testing. After meeting the requirements, the netting construction can be carried out.
4. The mesh must be firmly connected to the column, and the mesh surface should be flat after installation, without obvious warpage and unevenness. After the isolation fence is implemented, the High Commissioner Office will organize relevant personnel to check and accept the quality of the fence.
