Cable trench cover plate

If the construction work of cable trench cover is not done well, it will directly affect the normal traffic of the road, so its construction is a very critical issue. Below, the editor will analyze what needs to be prepared before the construction of composite cable cover.

2. Cement should have relevant factory qualification certificates and retest results reports.
2. Cement should have relevant factory qualification certificates and retest results reports.
3. Welding electrodes must have relevant qualification certificates, and the workers responsible for welding must hold work permits.
3. Welding electrodes must have relevant qualification certificates, and the workers responsible for welding must hold work permits.
4. The thickness, model, and specifications of the angle steel must meet the design requirements, and a certificate of conformity is required. The appearance inspection must be intact, without deformation or warping.
2、 Preparation of prefabrication site
2、 Preparation of cable trench cover plate for prefabrication site: The prefabrication site should not affect the construction site, so it should be located in the substation area. The surface of the site should be polished, and the surface should be smooth, tidy, and sufficiently solid. The size of the site should be determined based on the quantity of prefabrication and usage time.
The prefabrication site for cable trench cover plates should not affect the construction site, so it should be located in the substation area. The surface of the site should be smoothed and ensured to be smooth, flat, clean, and sufficiently solid The size of the site should be determined based on the quantity of prefabrication and usage time 3、 Technical Preparation 3: According to the relevant rules of State Grid Corporation of China, it is required to do a good job in drawing inspection. Technical disclosure should be carried out for each sub item of the project, and the disclosure should be targeted. It is required that all personnel participating in the construction must sign and record the disclosure work.

It is important to carefully understand and follow them before construction to ensure quality.
