Construction method of water supply and drainage pipeline
The invention relates to a construction method of a water supply and drainage pipeline. The construction method of the water supply and drainage pipeline comprises the steps that (1) construction preparation is carried out, specifically, the laying positions of water conveying transverse pipes are surveyed and determined; (2) the water conveying transverse pipes are laid, specifically, prefabricated pipe bases are evenly arranged in the length direction of a pipeline arrangement groove at intervals; (3) a cast-in-place pipe base and a pipe groove filling body are constructed; (4) blocks around a shaft are laid, and a mortar layer of the shaft is constructed; (5) a cast-in-place section of the shaft is constructed; (6) filling bodies around the shaft are constructed; (7) supporting bedplates and connecting rib plates are arranged; and (8) shaft lid plates are arranged. The construction method of the water supply and drainage pipeline has the beneficial effects that the arrangement precision of the water conveying transverse pipes is improved, the longitudinal supporting stability of the water conveying transverse pipes is effectively improved, the flatness and the construction efficiency of the mortar layer of the shaft are effectively improved, an inner die of the shaft can be quickly disassembled and assembled, the pouring construction difficulty of the cast-in-place section of the shaft is reduced, the bearing capacity of soil around the shaft at the lower parts of the shaft lid plates is effectively improved, shaft lid bottom beam connection meets the load sharing effect of the shaft lid plates, and the concentrated stress of the connecting parts of the shaft lid plates and shaft lid supporting bodies can be effectively reduced.
本发明涉及一种给排水管道的施工方法，包括步骤：1)施工准备：勘测确定输水横管的铺设位置；2)输水横管铺设：先沿管道布设槽长度方向均匀间隔布设预制管座；3)现浇管座及管槽填充体施工；4)井周砌块砌筑及井筒砂浆层施工；5)井筒现浇段施工；6)井周填充体施工；7)支撑台板及连接筋板布设；8)井盖板布设。本发明的有益效果是：提高了输水横管的布设精度；有效提升输水横管纵向支撑的稳定性；有效提升井筒砂浆层的平整度和施工效率；实现井筒内模的快速拆装，降低了井筒现浇段浇筑施工的难度；有效提升井盖板下部井周土体的承载能力；井盖底梁连接满足井盖板荷载分担的作用，可有效减小井盖板与井盖支撑体相接部位的集中应力。
