The invention discloses a construction method of a drainage pipeline project. The construction method comprises the steps that a groove is excavated; building an inspection well; setting piping is laid between the adjacent inspection wells, and backfilling is conducted on the two sides of the setting piping and the peripheries of the inspection wells according to the current specification requirements; a hose which is manufactured according to the distance between the adjacent inspection wells, meets the structural design requirement of an existing drainage pipeline and can be placed in a folded mode is pulled into (or turned over into) shaping piping, and curing is conducted; and performing a closed water test, and backfilling the soil to meet the road construction requirements after the closed water test is finished. According to the method, an in-situ curing method and a drainage pipeline excavation construction method are combined, the drainage pipeline which is continuous, free of connectors, capable of meeting the structural design requirement of an existing drainage pipeline and controllable in pipe length is generated in an on-site curing forming mode, the blank that a newly-built drainage pipeline is assembled in a non-site mode and is directly cured and formed in the site is filled, and the construction efficiency is improved. The defect that a plurality of connectors exist when the drainage pipeline is assembled on site is effectively overcome, and the long-service-life operation cycle of the newly-built drainage pipeline can reach more than 50 years.
本发明公开了一种排水管道工程的施工方法，包括开挖沟槽；检查井砌筑；在相邻检查井之间敷设定型配管，在定型配管两侧和检查井四周按现行规范要求进行回填；将根据相邻检查井之间距离制作的、满足现行排水管道结构设计要求、可折叠放置的软管拉入(或翻转进入)定型配管，并固化；进行闭水试验，完毕后将土回填至道路施工要求。本发明将原位固化法与排水管道开挖施工法相结合，通过现场固化成型的方式生成连续无接口、满足现行排水管道结构设计要求、管长可控的排水管道，填补了新建排水管道非现场装配而现场直接固化成型的空白，有效解决排水管道在现场装配时存在众多接口的缺陷，使新建排水管道达到50年以上的长寿命运行周期。
