Drainage pipeline system, construction method and leakage detection method
The invention discloses a drainage pipeline system, construction method and leakage detection method. The drainage pipeline system, construction method and leakage detection method solve the problem that a leakage detection method of a drainage pipeline system at the present stage is too complicated. According to the technical solution, the drainage pipeline system is characterized by comprising at least two detection wells and drainage pipelines arranged between the adjacent detection wells, wherein each drainage pipeline comprises a plurality of pipeline units which are spliced in a sealed mode, each pipeline unit comprises an inner pipe and an outer pipe, a closed detection cavity is formed between each inner pipe and the corresponding outer pipe, the drainage pipeline system further comprises a detection pipeline, the detection pipeline comprises a detection main pipe and a detection branch pipe for communicating the detection main pipe with a detection chamber, an air pressure sensor is arranged on one end of the detection main pipe, a sealing plug is detachably installed on the other end of the detection main pipe, and a first electromagnetic valve for controlling the detection main pipe to communicate with the detection chamber is arranged on the detection branch pipe. The drainage pipeline system has the advantage of being simple and convenient in leakage detection.
本发明公开了一种排水管道系统、施工方法及检漏方法，解决了现阶段的排水管道系统检漏方法过于繁杂的问题。其技术方案要点是一种排水管道系统，包括至少两个检测井和设于相邻所述检测井之间的排水管道，所述排水管道包括多根密封拼接的管道单元，所述管道单元包括内管和外管，所述内管和所述外管之间形成有密闭的检测腔室；所述排水管道系统还包括检测管道，所述检测管道包括检测主管和连通所述检测主管与所述检测腔室的检测支管；所述检测主管的一端设有气压传感器，所述检测主管的另一端可拆卸安装有密封堵头；所述检测支管设有控制检测主管和检测腔室连通的第一电磁阀，所述排水管道系统具有检漏简便的优点。
