The pipe box is made of fiberglass and resin, which inevitably produces burrs in the production. This is not a cable, because the cable is thick and dare not touch, but the cable is different. In addition, the cable is a copper core, and even if it is punctured, it does not affect the glass fiber used, but the cable is fiber, which is a wrong signal. The power of cable channels (cable channels). The power construction specification requires a depth of 1.2 m, and the pressure and shock directly affected by the pipe layer is at least 1.2 m.

 The communication pipe depth of the pipe box pipeline construction is 70 cm. Many places are built and other pipelines due to construction or landfill, so the depth of the digging reaches the design requirements. In some places, it is only 20-30 cm, and the landfill project is the shallowest. 10 cm, which also includes the sidewalk. Cable channels (cable channels) are not suitable for this kind of shallow. Steel pipes are generally 20 years old. Maintenance is difficult and expensive during frequent operations during maintenance. When the pipeline is buried underground, it is surrounded by water quality, soil, groundwater, and the presence of surrounding factors in the laying zone.

  In the construction of cables in railways, pipe-box roads, etc., the cable supports are first fixed in the corresponding positions. The cable supports are mainly divided into two types, one is a steel hot-dip galvanized cable support, and the other is a composite cable support. FRP cable bracket, then place the box part of the tube box on the cable bracket, and then put the cable into the tube box along the slot box, and finally check the cover part of the cover without any problem, so that The electricity bill will be put into the pipe box. If there is fireworks, the weapon will unfortunately wait for the accident, the cable will not directly touch the outside, the pipe box is generally fireproof, and the strength is also high, the weapon is not easy to damage, so the cable It plays a very good protective role, and it provides a good protective coat for the transportation of electricity and guarantees people's electricity consumption.
