Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly relates to a multi-directional joint for a municipal engineering drainage pipe. Background Art

[0002] Municipal engineering drainage pipes refer to rainwater and sewage pipes under municipal roads, that is, sewer pipes, which are usually called municipal drainage pipes in engineering. Municipal drainage pipes usually classify and discharge rainwater and sewage, that is, rainwater is discharged into rivers nearby, and sewage is discharged into sewage treatment plants. Therefore, a multi-directional joint for drainage pipes is used. Because the multi-directional joint has one more water pipe joint than those on the market, the time cost for installation is relatively more. However, when the existing multi-directional joints for municipal engineering drainage pipes are docked and installed, they are usually fastened and installed by setting bolts, and the operation is too cumbersome, which is inconvenient for the staff to operate, resulting in a reduction in installation efficiency.
