A kind of municipal drainage pipeline construction technology

Abstract

A municipal drainage pipeline construction technology is used to solve the technical problem that cement mortar is used to seal the joints of concrete pipes, which is easy to cause water leakage at the joints of concrete pipes. It includes the following steps: excavating a trench, placing the first concrete pipe in the trench, snapping a first sealing ring at the end of the first concrete pipe along the circumferential direction of the end, and sheathing a second sealing ring on the periphery of the connecting pipe. A sealing ring, one end of the connecting pipe is inserted into the first concrete pipe from the end of the first concrete pipe, at this time the second sealing ring is in contact with the first sealing ring and the two are sealed, and the second concrete pipe is placed in the groove The third sealing ring is clamped at the end of the second concrete pipe along the circumferential direction of the end, and the end of the second concrete pipe is sleeved on the connecting pipe from the other end of the connecting pipe. At this time, the third sealing ring Abutting with the second sealing ring and sealing both, and the first sealing ring and the third sealing ring abutting and sealing, and then backfilling the groove, the process of the present invention is simple, and 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 construction projects of concrete pipes and pipelines. This kind of pipeline construction is mostly used in the construction conditions of crossing roads or other obstacles. A more important construction process in the construction of concrete pipes is to seal between two adjacent concrete pipes. For waterproof treatment, the existing treatment method is that the construction...

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
