When laying in a fully enclosed bridge, pay attention to these issues:

1. Clean and sweep. A good working environment is the key to whether the work can be carried out in an orderly and effective manner, so we must clean up the line pipe in advance, and clean up the dirt and water in the pipe.

2. Orderly and disorderly. When laying cables or wires inside a fully enclosed bridge, we must first make sure that the cables or wires are neatly arranged. It is better if they can be bundled. In this process, it should be noted that the cable must not be twisted, spliced, armor flattened, the sheath is broken, and the surface is severely scratched.

3. The basic insulation work should be done well, and the work such as sealing and waterproofing can not be ignored.

4. We can have clear logos on various cables, so that it can be more convenient for our future maintenance and repair.
