FRP pipe is not only suitable for electric power engineering, communication cables are repaired when buried in the ground, but also can be used for direct burying of cables crossing motor vehicle lanes or repairs when paving traffic trunks. Cables are unique in crossing bridges, culverts, and rivers. Maintenance of the natural environment is used for the basic construction and transformation of the power network, the transformation of large-scale urban municipal projects, civil aviation airports, industrial areas, residential district projects, and construction projects along the main traffic lines.
However, when the FRP pipe is broken, the safety of the cable cannot be guaranteed. Why does fiberglass steel pipe appear cracks? The key to the problem lies in the following:
One is that there is a lot of water when excavating the groove of glass steel pipe, and the groove becomes soft after being soaked in water, which causes the groove to collapse;
Second, in the trench excavation of the glass steel pipe, the whole groove is not completely done, and some sharp foreign objects pierce the glass steel pipe, causing the glass pipe to be damaged, thereby losing the protection of the cable;
The third is that the impact force is very large when FRP is filled;
Fourth, the foundation on which the FRP trench is located is soft, and the filler sinks unevenly, which causes the deep buried FRP to be torn and loses its protective effect on the cable.
Glass tube characteristics: handy steel frame garden structure, earthquake-damaged concrete antifreeze, maintain the diversity of the natural landscape, maintain and penetrate, and cause harm to the plant community. In the basic construction of permanent engineering projects, the actual effect of maintaining the use period of the natural landscape is 50m100.
In view of the above four problems, the following improvement plans are summarized, and I hope it will be helpful to everyone:
- When digging the grooves of FRP pipes, always pay attention to the accumulation of water. When the accumulation of water occurs, promptly drain the accumulated water. the groove wall needs to be inspected repeatedly to remove as many foreign objects as possible. When choosing FRP pipes, you need to choose better quality FRP pipes. For example, the quality of FRP pipes produced by MIYABI is good;
- When filling the grooves of FRP pipes, a filter screen should be used to remove foreign objects such as stones;
- Before laying FRP pipes, the foundation at the bottom of the trench needs to be tamped
