Device and method for plugging municipal drainage pipeline with water without descending well
The invention discloses a water-carrying plugging device and method for a municipal drainage pipeline without descending a well, and belongs to the technical field of municipal drainage pipeline sealing. The device comprises a wellhead fixing frame, an air bag positioning mechanism, a drainage pipeline and an inspection well, the air bag positioning mechanism comprises a telescopic rod and an air bag limiting barrel, the air bag limiting barrel is connected with the well mouth fixing frame through the telescopic rod, the telescopic rod extends out of a well mouth of the inspection well, the end of the air bag limiting barrel is connected with a well wall backrest plate, a jacking air bag and a blocking air bag are arranged in the air bag limiting barrel, and the well wall backrest plate is connected with the air bag limiting barrel. One end of the jacking air bag abuts against the well wall backboard, the other end of the jacking air bag abuts against the blocking air bag, and the blocking air bag is located at an outlet of the air bag limiting barrel. The device is simple in structure, convenient to operate and controllable in air bag plugging quality, air bag plugging work in a drainage pipeline can be effectively conducted, the safety management problem that air bag plugging workers need to go down to a well can be solved, and operation is safe and convenient.
本发明公开了一种市政排水管道不下井带水封堵装置及方法，属于市政排水管道封闭技术领域。该装置包括井口固定架、气囊定位机构、排水管道和检查井；所述气囊定位机构包括伸缩杆和气囊限位筒，所述气囊限位筒通过所述伸缩杆与所述井口固定架连接，所述伸缩杆伸出所述检查井的井口，所述气囊限位筒的端部连接有井壁靠背板，所述气囊限位筒内部设置有顶进气囊和封堵气囊，所述顶进气囊的一端与所述井壁靠背板抵接，另一端与所述封堵气囊抵接，所述封堵气囊位于所述气囊限位筒的出口处。本发明结构简单、作业方便，气囊封堵质量可控，能够有效进行排水管道内的气囊封堵工作，并且可解决气囊封堵作业人员需下井作业的安全管理问题，作业安全且便利。
