Description

[0001] The invention relates to the technical field of building construction equipment, and in particular to a drainage pipe docking device. Background Art

[0002] Drainage pipes refer to a system consisting of pipes and ancillary facilities that collect and discharge sewage, wastewater and rainwater. At present, drainage pipes are usually installed underground, that is, a trench is first opened on the ground, and then the drainage pipe is installed in the trench, and then the trench is filled so that the drainage pipe is buried underground. The underground installation of drainage pipes has the advantages of saving space, protecting urban landscape, reducing damage and interference, good stress conditions, protecting the environment, and safe and reliable operation. These advantages make buried drainage pipes an indispensable part of urban infrastructure construction.

[0003] At present, there are two main ways to install buried drainage pipes. One is to weld multiple sections of drainage pipes above the trench, and then hoist the welded pipes into the trench; the other is to first hoist multiple sections of drainage pipes into the trench, and then have the staff enter the trench to perform hot-melt connection. At the corner of the trench, when elbows or tees are required to be configured on the pipe, the overall welding method above the trench is adopted. When hoisting the welded pipes, multiple hoisting equipment are required at the same time, and the hoisting process is relatively inconvenient; and the method of having the staff enter the trench for hot-melt connection is difficult to operate due to the limited space at the corner of the trench.
