Precautions for installation of double-circle guardrail net
When carrying out concrete foundation construction on guardrail columns, the construction unit shall release the center line of the foundation and perform necessary leveling and cleaning of the site in accordance with the requirements of the approved construction organization design and design drawings. Ensure that the isolation fence is beautiful and straight in shape after installation. Before foundation concrete is poured, the size of the foundation pit and the spacing between foundation pits must be inspected and approved by the supervision engineer before concrete pouring can be carried out.
During the installation process of the columns, it is necessary to ensure that the columns are stable and tightly connected to the foundation. If necessary, supports can be installed to stabilize the columns. During the column installation process, small lines should be used to detect the straightness of the column installation and make local adjustments. Make sure the straight sections are straight and the curved sections are smooth. The burial depth of the columns must comply with the requirements of the design drawings. After the construction of the columns is completed, the supervision engineer must detect the linear burial depth of the columns and the stability of the connection with the foundation. Only after meeting the requirements can the net hanging construction be carried out.
The mesh must be firmly connected to the columns. The mesh surface should be flat without obvious warping or unevenness after installation. After the construction of the isolation fence is completed, the Gao Resident Office will organize relevant personnel to inspect the quality of the guardrail network.
