Construction method of buried reinforced HDPE spiral corrugated pipe
The invention provides a construction method of a buried reinforced HDPE spiral corrugated pipe. The construction method of the buried reinforced HDPE spiral corrugated pipe comprises the steps that the center position of a sewage well and the center line of a sewage pipeline are determined based on a GPS-RTK system; a foundation trench excavation line is determined, and a trench is excavated along the foundation trench excavation line; an inspection well chamber and a launder are synchronously built according to preset requirements, hole pouring is carried out at intervals for several times to the 2/3 position of an uppermost building block, and the rest building blocks are tamped; reserved branch pipes and steps are installed along with building of the inspection well chamber ,and pointing is conducted on a well wall of an inspection well through cement mortar; after the inspection well is built to a preset elevation, a cover plate, a well ring and a well lid are installed; 360-degree sand foundation construction is carried out by adopting a 100mm medium sand cushion layer; according to an elevation of a sand foundation and the center line of the sewage pipeline, an HDPE spiral corrugated pipe is laid; after ensuring that no water is accumulated in a groove, a pipeline water closing test is carried out according to well spacing separation of the inspection well; and groove backfilling is conducted according to a backfill soil with the predetermined maximum dry density and the optimal water content.
本申请提供了一种埋地增强HDPE螺旋波纹管施工方法，包括：基于GPS‑RTK系统，确定污水井的中心位置以及污水管道的中心线；确定基槽开挖线，并沿基槽开挖线开挖沟槽；按预设要求同步砌筑检查井井室和流槽，分次间隔灌孔至最上层砌块的2/3处，其余进行捣固；随检查井井室的砌筑同时安装预留支管以及踏步，且检查井井壁采用水泥砂浆进行勾缝；检查井砌筑至预设高程后，安装盖板、井圈以及井盖；采用100毫米中砂垫层，进行360°砂基基础施工；根据砂基基础高程和污水管道的中心线，敷设HDPE螺旋波纹管；确保沟槽内无积水后，按检查井的井距分隔进行管道闭水试验；按照预先确定的最大干密度和最佳含水量的回填土进行沟槽回填。
