This paper explains the problems encountered in the construction of municipal water supply and drainage pipelines (HDPE double-wall corrugated pipe, hollow wall winding pipe, PE drag pipe, PE water supply pipe, PVC double-wall corrugated pipe, carat pipe, HDPEM alloy pipe).
1, the preparation work is not in place
the construction unit is not detailed and in-depth on the site investigation work, resulting in unreasonable quality control plan preparation, as well as the construction period, inspection procedures and methods, quality control points and control levels.
2, There are problems in the design of sediment wells. In the construction design process of some municipal engineering water supply and drainage pipelines, there is no independent design of the sediment wells, which often leads to the blockage of the drainage pipes of municipal engineering.
3, If the construction plan of the drainage well is not perfect, if the construction plan is not scientifically and reasonably designed, it is easy to lead to the travel of the public being hindered. In addition, in the process of drainage well construction, there is often a certain amount of gravel residue.
4, material and process problems There are defects in the quality of construction equipment and engineering materials: aging and rust of pipelines and components, trachoma and other phenomena.
Defects in construction technology: Defects in construction technology and technical level make the pipe fittings not have enough processing accuracy, not tight sealing or slope problems.
Serious backfill settlement: The backfill compaction operation is not in place, the soil layer is stable and the strength is not up to standard, and the water content exceeds the standard, resulting in serious backfill settlement.
