Description

Technical Field

[0001] The utility model relates to the technical field of pipeline opening blocking, in particular to a pipeline opening blocking device. Background Art

[0002] During the construction of municipal public facilities, due to the high coverage rate of concrete areas on the bottom surface of the city, it is difficult for precipitation to directly penetrate into the ground. In order to quickly drain the water on the ground and prevent urban waterlogging, a large number of rainwater and sewage pipes need to be buried underground to achieve rapid drainage. In order to achieve a balance between cost and drainage needs, generally speaking, the diameters of rainwater and sewage pipes installed in different regions and at different nodes are different, and the materials of rainwater and sewage pipes are also different. The materials may be selected as steel pipes, corrugated pipes, fiberglass pipes or concrete pipes according to actual needs; when water leakage occurs during the construction process, resulting in flooding of the foundation pit on site, it will cause greater harm;

[0003] Among them, the existing patent CN202323220305.7 is a water supply and drainage pipe sealing device, which is sealed by squeezing and fitting a compressed rubber cylinder with the inner wall of the pipe. Compared with the air bag expanding by inflation, the sealing performance of the device is greatly improved. At the same time, two groups of compressed rubber cylinders are used at the same time, which effectively avoids leakage and water leakage. At the same time, the device is provided with an auxiliary support mechanism, which cooperates with the compressed rubber cylinder in the squeezed state, so that the device can withstand greater water pressure and has strong applicability. At the same time, the device adopts an independent power supply and does not need to be connected to other equipment when using the device. While ensuring the independent use of the device, it also improves the safety of the device and greatly improves the practicability of the device.

[0004] However, most of the existing pipe opening plugging equipment used in pipe network renovation projects cannot be properly adjusted and subsequently fixed according to pipes of different diameters. When the position of the pipe changes, the plugging will become loose, affecting the plugging effect of the pipe. At the same time, when plugging the water pipe, it can only be blocked but not buffered, and it is easy to be damaged by the impact of water flow, reducing the plugging effect. Therefore, it does not meet the existing needs. We have proposed a pipe opening plugging device. Utility Model Content
