Municipal drainage pipeline construction technology

Abstract

The invention discloses a municipal drainage pipeline construction process. The municipal drainage pipeline construction technology is used for solving the technical problem that water leakage is easily caused at splicing positions of concrete pipes when cement mortar is used for sealing the splicing positions of the concrete pipes. Comprising the following steps that a groove is excavated, a first concrete pipe is arranged in the groove; a first sealing ring is clamped to the end of the first concrete pipe in the circumferential direction of the end, a second sealing ring is arranged on the periphery of a connecting pipe in a sleeving mode; and one end of the connecting pipe is arranged in the first concrete pipe in a penetrating mode from the end of the first concrete pipe; at the moment, the second sealing ring and the first sealing ring abut against each other and are sealed; a second concrete pipe is arranged in the groove, a third sealing ring is clamped to the end of the second concrete pipe in the circumferential direction of the end; and the end of the second concrete pipe is arranged on the connecting pipe from the other end of the connecting pipe in the sleeving mode; at the moment, the third sealing ring and the second sealing ring abut against each other and are sealed, the first sealing ring and the third sealing ring abut against each other and are sealed, and then the groove is backfilled. According to the municipal drainage pipeline construction technology, procedure is simple, and the municipal drainage pipeline construction technology is mainly used for pipeline construction.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a municipal drainage pipeline construction technology. Background technique [0002] Municipal pipeline construction is an important construction project of municipal infrastructure construction. At present, there are many kinds of pipeline materials involved in municipal pipeline construction, including concrete pipes, steel cylinder concrete pipes, ductile iron pipes and rubber pipes, etc. Different pipe materials All have matching construction techniques. [0003] At present, there are many concrete pipe and pipeline construction projects. This kind of pipeline construction is mostly used in the construction conditions of crossing roads or crossing some other obstacles. One of the more important construction procedures in concrete pipeline construction is to seal the gap between two adjacent concrete pipelines. Waterproof treatment, the existing treatment method...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned sealing method, when the cement mortar is hardened, especially when the concrete pipe needs to be backfilled and covered in the later stage, the concrete pipe is likely to be disturbed during the backfilling process, and this kind of disturbance is likely to cause the hardened cement mortar to crack. There is a bad phenomenon of water leakage at the joint of two adjacent concrete pipes
