1. Before installing the cable conduit box, a bracket should be set up on the bridge. The size of the support bracket depends on the specifications of the selected cable conduit box, but the spacing should not exceed 1500mm, usually made of angle steel.

2. Place the cable conduit box on the bracket, and once the position is determined, use a handheld drill to drill through the cable conduit box and support frame at the position of the support frame. Then tighten them with bolts, drill two holes with a diameter of 10mm on each support frame, and use two sets of M8 bolts.

3. At the joint of the cable conduit box, socket type joints and joint cover plates should be used to connect the two sections of the cable conduit box as a whole.

4. The connection between cable conduit boxes and roadbed cables can be made using concrete pipes or steel pipes.

5. Connect the fiberglass cable box elbow to the pipe box at the turning point of the road.

6. The box cover and box body are fixed with plastic bolts and stainless steel bolts.
