Installation of chain link fence mesh, pouring concrete foundation of column, and overall fastening and adjustment of the fence.
1. Surveying and lofting: Carry out construction lofting according to the design requirements of the drawings and the actual terrain and ground conditions, determine the center line of the column, and install the fence according to the specified slope and line.
2. The original ground treatment is an important prerequisite to ensure the smooth and overall firmness of the protective fence installation. The weak layer under the foundation must be replaced and compacted before the column can be buried to ensure the firmness of the column. Column installation should be carried out in sections. From a longitudinal perspective, the axis of the column should be in a straight line and should not be uneven; from a height perspective, the top of the column should be smooth and should not be uneven, except for special terrain.
3. According to the measurement and stakeout, set up benchmarks and white lines, fill and dig the original surface and follow the slope, and ram it again, install the stakeout position to excavate the column foundation pit to ensure the size of the foundation pit.
4. During the installation of the column, the stability of the column and the close connection with the foundation must be ensured. During the installation of the column, a small line is used to detect the straightness of the column installation, and the local adjustments are made to ensure that the straight section is straight and the curved section is smooth. Column fixation meets the requirements of design drawings.
5. The mesh must be firmly connected to the column, and the mesh surface should be installed smoothly without obvious warpage and unevenness.
6. After the column is temporarily positioned and installed, install the rails, and after ensuring that the installation is correct and firm, pour the concrete foundation and maintain it in time.
