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...

Examples

Embodiment Construction

[0022] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like figure 1 and figure 2 As shown, a municipal drainage pipeline construction process includes the following steps:

[0024] S1. Excavate the trench 1 according to the design requirements, remove the debris and floating soil in the trench 1, compact the foundation at the bottom of the trench 1 and level the foundation;

[0025] S2. Place the first concrete pipe 2 in the groove 1, and clamp the first elastic sealing ring 3 at the end of the first concrete pipe 2 along the circumferential direction of the end. The upper edge of the first sealing ring 3 is A first clamping groove 8 is opened in the circumferential direction, the inner wall of the first clamping groove 8 is coated with adhesive, and the end of the first concrete pipe 2 is clamped and connected with the first clamping groove 8 and the two are sealed;
