Anti-leakage device for rain and sewage pipeline, its manufacturing method and its use method

Abstract

The present invention discloses a rainfall and sewage pipe leakage prevention device, a manufacturing method and a use method thereof. The device comprises waterproof internal bags, a waterproof internal bag plate rack, floating balls and bag collars. The waterproof internal bag is coiled on a roller of the waterproof internal bag plate rack. The floating balls are arranged on the free end of the waterproof internal bags. The waterproof internal bags on two ends of the floating balls are tightened to fix the floating balls. The manufacturing method comprises: (1) manufacturing the waterproof internal bags; (2) installing and fixing the waterproof internal bags; (3) fixedly setting the floating balls; and (4) selecting the bag collars matching with the rainfall and sewage pipe. The use method comprises: (1) opening an inspection shaft; (2) selecting the waterproof internal bags; (3) putting them in the rainfall and sewage pipe; (4) taking out the floating balls so that the water flows into the waterproof internal bags; and (5) tightening the waterproof internal bags on the external circumference of the port of the rainfall and sewage pipe with the bag collars. The rainfall and sewage pipe leakage prevention device in the present invention prevents the rainfall and sewage pipe from leaking during the construction period and guarantees normal construction.

Description

technical field [0001] The invention belongs to the technical field of municipal pipeline maintenance and protection engineering, and in particular relates to an anti-leakage device for rainwater and sewage pipelines in a construction disturbance area, a manufacturing method and a using method thereof. Background technique [0002] In recent years, with the continuous development of high-rise buildings and urban underground space, the number of underground projects such as foundation pit projects and tunnel projects in my country has increased rapidly. It is easy to deform the position of the pipe joint, resulting in cracks, joint dislocation, sinking and other phenomena. Urban rainwater and sewage pipelines are responsible for important functions such as urban rainwater and sewage discharge. Since most of them are buried underground, they are hidden projects. Once leakage occurs, it will cause water ingress in foundation pits and tunnels under construction, endangering the p...

Problems solved by technology

Urban rainwater and sewage pipelines are responsible for important functions such as urban rainwater and sewage discharge. Since most of them are buried underground, they are hidden projects. Once leakage occurs, it will cause water ingress in foundation pits and tunnels under construction, endangering the personal safety of relevant construction personnel and causing serious damage. Affect the construction progress; more serious ones will cause ground subsidence accidents and affect social stability, and such accidents are often sudden, harmful, and difficult to predict
