Construction method of prefabricated concrete socket rainwater pipe

Abstract

The invention provides a construction method of a prefabricated concrete socket rainwater pipe. The construction method comprises the steps that firstly, a pipe body is horizontally placed; secondly, a sealing ring is installed on the end face of the small end of the second pipe body; thirdly, the first lifting lug of the second pipe body is lifted through a lifting hook; fourthly, a second pipe body is hoisted to the first pipe body, and the installation mode is that the small head of the second pipe body is placed in the lower half large head of the first pipe body from top to bottom, the position of the small head is adjusted, the small head is located in a groove in the bottom of the lower half pipe, and the second pipe body is installed on the second pipe body. The end of the small head abuts against the inner side end face of the groove in the bottom of the lower half pipe. Fifthly, the second lifting lug of the first upper half big head is lifted through a lifting hook; and sixthly, the first upper half large head is installed on the lower half large head of the first pipe body. The pipeline can be placed from top to bottom, balance adjustment is not needed, installation is easy, the working efficiency is improved, workers needing to be matched are reduced, and cost is saved.

Description

【Technical field】 [0001] The invention relates to the technical field of socket and insertion pipes, in particular to a construction method of a precast concrete socket and insertion rainwater pipe. 【Background technique】 [0002] In the construction of concrete socket rainwater pipes, cranes or excavators are usually used to suspend the sling, tie the sling to the rainwater pipe, adjust the balance position, lift, and then cooperate with three or four workers to repeatedly adjust the position. For a good hole, insert the small end of the pipe into the big end of the other pipe horizontally, and then use the machine to move the small end of the pipe completely into the big end to ensure that the two pipes are tightly socketed, and then use cement mortar to point the joints to ensure the tightness of the pipe joints. . [0003] This traditional construction method: It takes a certain amount of time to find the center of gravity (balance point) of the pipeline and put the sli...

Problems solved by technology

[0003] This traditional construction method: it takes a certain amount of time to find out the center of gravity (balance point) of the pipeline and put the sling in. Secondly, the lifting will test the skill of the crane driver. For unskilled drivers, adjust the pipeline to the correct position. It takes a lot of time to perform translation operations, such as positioning, and the work efficiency is extremely low
