Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and in particular to a water supply and drainage pipeline construction device. Background Art

[0002] With the gradual development of urbanization, municipal water supply and drainage, as a key component of urban infrastructure, has drawn increasing attention. Municipal water supply and drainage projects not only effectively remove accumulated water from urban areas and provide water for industrial and domestic use, but also prevent the pollution of urban water resources. Common water supply pipes include galvanized steel pipes, ductile iron pipes, aluminum-plastic pipes, and plastic-lined steel pipes.

[0003] Municipal rainwater pipes are usually connected in sequence using socket-and-spigot pipes. During the construction process, excavators and other lifting equipment are generally used to lift the pipes into the installation trench with lifting ropes and connect them to the previous pipes. This process requires multiple people to assist in controlling the position of the pipes. During the docking process, it is easy for the pipes to collide, causing damage to the appearance of the pipes and safety accidents caused by collisions between people. It is difficult to achieve stable docking, resulting in low construction efficiency. Therefore, corresponding improvements have been made to address this problem. Summary of the Invention
