Application of PE pipe in drainage
The pipe is connected to the inspection well. In the original construction plan, the nozzle was retracted into the inner wall of the inspection well by 0.3 m to 0.5 m, and it was painted with a mortar to form a "horn".
The mortar is filled with compaction, and then the bricks are built, but the closed water test cannot meet the requirements. The following problems are found after inspection:
1PE tube thermal expansion and contraction will check the well cracking, resulting in inspection well leakage.
2 The inspection well was not cracked, but the sealing at the joint between the pipeline and the inspection well did not meet the requirements, resulting in seepage and water leakage.
