1. When the mesh and column used in the double wire fence is transported to the construction site, the construction unit must provide the product qualification certificate to the supervision engineer. 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 the linearity after the isolation fence is installed. 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 of the column, the stability of the column 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 installation of the column and adjust the local area. Make sure that 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 linear depth and height of the column and the stability of the connection with the foundation. After the requirements are met, the net-hanging construction can be carried out.
3. The mesh must be firmly connected with the column, and the mesh surface should be flat after installation, without obvious warping and unevenness. After the construction of the isolation fence is completed, the High-level Resident Office will organize relevant personnel to check and accept the quality of the fence.
