An emergency water stop device for underground pipelines

Abstract

The invention discloses an emergency water stopping device for an underground pipeline. The emergency water stopping device comprises a fixing mechanism, a first fastening mechanism and a second fastening mechanism are symmetrically and fixedly installed at the upper and lower ends of the fixing mechanism, a first fixing hood and a second fixing hood are symmetrically installed in the middle of the fixing mechanism, and auxiliary fixing clamping rings are symmetrically welded to the two ends of the first fixing hood and the two ends of the second fixing hood; an air inlet pipe and an exhaust switch fixedly penetrate through and are inserted in the first fixing hood, sealing hood plates are fixedly connected to the ends, deviating from the first fixing hood and the second fixing hood, of the auxiliary fixing clamping rings, rubber sealing pads are fixedly embedded in the sealing hood plates, and blocking gasbags are fixedly installed in the first fixing hood and the second fixing hood.The device can be quickly detached and installed, the broken sewer line can be quickly subjected to water stopping for a long time, it can be ensured that the broken pipeline is sealed and blocked byfilling the blocking gasbags with high-pressure gas, and the water stopping effect is better.

Description

technical field [0001] The invention relates to the technical field of municipal pipeline maintenance equipment, in particular to an emergency water stop device for underground pipelines. Background technique [0002] Underground pipes are mainly used to transport some rainwater and domestic sewage. Especially in the rainy season, underground drainage pipes can also ensure that the precipitation in the city can be discharged quickly, ensuring that people can travel smoothly in the rainy season. Underground pipes are corroded during use. There will be cracks or holes in the pipeline due to other reasons. At this time, rainwater and sewage will seep out of the drainage pipeline during the drainage process. Therefore, it is necessary to urgently stop the water from the ruptured underground drainage pipeline to ensure its perfect drainage function. It is also convenient for maintenance, but the installation and disassembly of the existing underground pipeline emergency water sto...

At this time, rainwater and sewage will seep out of the drainage pipeline during the drainage process. Therefore, it is necessary to urgently stop the water from the ruptured underground drainage pipeline to ensure its perfect drainage function. It is also easy to maintain, but the installation and disassembly of the existing underground pipeline emergency water stop device is complicated during use, and the sealing is not good, so that the underground pipeline after the water stop will still have a lot of sewage discharged
