Construction method of bell and spigot concrete pipe

Abstract

The invention relates to a construction method of a bell and spigot concrete pipe. The construction method effectively solves the problems that in the butt joint installation process of an existing bell and spigot concrete pipeline, operation is inconvenient, and pipeline collision is likely to be caused to cause damage. According to the technical scheme, after a to-be-installed pipeline is placedinto an excavated and leveled tunnel, through mutual cooperation of an expansion rod and a Z-shaped rod, when the to-be-installed pipeline is away from an installed pipeline by a certain distance, the effect of accurate alignment of the to-be-installed pipeline and the installed pipeline can be achieved, and then butt joint is achieved through an electric push rod. Compared with a traditional manner that alignment can be completed by moving the to-be-installed pipeline to the position close to the installed pipeline, the situation that in the alignment process of the pipeline, collision is likely to happen due to the close distance, and consequently damage is caused is further reduced, and the butt joint process of the pipeline is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of concrete pipe installation, in particular to a construction method for a socket socket concrete pipe. Background technique [0002] During the construction of sewage treatment projects, it is necessary to excavate tunnels to bury concrete pipes. For large-diameter socket concrete pipes, it is difficult for workers to construct due to their own weight. The traditional installation method is to use a crane and manually lift the concrete pipes into the trench. , and then manually cooperate with the winch to correct the deviation and realize the effect of butt-joining and installing the pipes together; [0003] When the workers correct the deviation of the pipeline to be installed in the tunnel, they need to move the socket of the pipeline to be installed near the socket of the installed pipeline, and then observe and judge with the naked eye and cooperate with the winch Manually adjust the position of the p...

Problems solved by technology

[0003] When the workers correct the deviation of the pipeline to be installed in the tunnel, they need to move the socket of the pipeline to be installed near the socket of the installed pipeline, and then observe and judge with the naked eye and cooperate with the winch Manually adjust the position of the pipe in the pipe trench to realize the butt connection and installation of the pipe. Due to the heavy weight of the concrete pipe and the short distance between the two pipes, it is easy for the socket of the pipe to be installed to be different from that of the installed pipe when the worker corrects it. Collision and friction between the pipe sockets will cause damage to the pipe joints or falling off of the bonding material, etc., so that when the socket-type concrete pipes are docked, the sockets will not be tightly connected, and cracks will easily appear, resulting in pipe docking after construction. Water seepage will seriously affect the construction quality;

[0004] Correcting the deviation by human eyes leads to a slow construction progress and greatly increases the workload of the workers, which puts a lot of work pressure on the construction team's pulleys;
