Description

Technical Field

[0001] The utility model relates to the technical field of municipal water supply projects, in particular to a water supply pipeline emptying, mud discharge and exhaust structure. Background Art

[0002] When a water supply pipeline passes through low-lying areas such as rivers and lakes, the elevation of the pipeline needs to be lowered locally, causing impurities and silt to settle in the low-lying areas of the pipeline. At the same time, the low-lying areas of the pipeline need to be drained during pipeline maintenance. Currently, the conventional construction method is to connect the mud discharge pipe and the water supply pipe with a tee at the bottom of the pipe. After the gate valve is opened in the mud discharge pipe, the impurities and silt are discharged into the mud discharge wet well, and then discharged to the outside through the overflow pipe in the mud discharge wet well. Due to the low-lying areas of the pipeline, the gate valve well and the mud discharge wet well are deep, and maintenance personnel need to go down to the deep well to operate, which poses a certain personal safety risk. In addition, the mud discharge wet well uses overflow drainage and cannot be completely emptied, and the actual mud discharge and emptying effect is not ideal. In addition, the gate valve well and mud discharge wet well are expensive and have a long construction period. Utility Model Content
