Problems solved by technology

[0004] During pipeline installation, it is necessary to seal the connection between adjacent pipelines. The existing method is usually to fill the gap between the two connected pipelines with mortar, so that the adjacent pipelines are sealed and connected. However, the adjacent pipelines are sealed by mortar When sealing between them, someone needs to drill into the pipe to smooth the interface, so it is very inconvenient during construction

Embodiment 1

[0045] Such as figure 1 , 2 As shown, a drainage pipe includes a pipe body 1, a socket 2 is provided at one end of the pipe body 1, and a socket 3 is provided at the other end of the pipe body 1, and the socket 3 can be plugged and matched with the socket 2 on the adjacent pipe body 1. , the outer wall of the socket 2 is provided with a first ring groove 4 around the socket 2, and the inner wall of the socket 3 is provided with a second ring groove 5 around the socket 3; when the socket 2 is inserted into the socket 3 of the adjacent pipe body 1, the first ring The groove 4 and the second annular groove 5 just butt each other and form a sealed cavity 6; an inlet 7 is provided on the socket 3, and the inlet 7 communicates the second annular groove 5 with the outer side of the socket 3.

[0046]Among them, the number of inlets 7 is multiple and distributed on the socket 3 along the circumferential direction of the socket 3. At the same time, the socket 3 is provided with an out...

Embodiment 2

[0053] A construction method for a drainage pipeline, comprising the following steps:

[0054] Step 1: Surveying and setting out, organize the surveying team to conduct retesting according to the surveying control points provided by the design institute, establish the engineering surveying control network after the review is correct, carry out the surveying and control of the project combining point and plane, set out the survey, and determine the pipeline centerline and well position, and set the leveling reference point as the control point of the whole project, each measurement must be closed, and the closing error should be strictly controlled;

[0055] Step 2: Trench excavation, determine the soil quality of the excavation area, and select the slope of the slope according to the soil quality, and excavate according to the appropriate slope;

[0056] Step 3: Dewatering in the trench, excavate a drainage ditch on both sides of the bottom of the trench excavated in step 2, a...

Abstract

The invention relates to a drainage pipeline and a construction method thereof. The drainage pipeline comprises a pipeline body, a spigot is formed in one end of the pipeline body, the other end of the pipeline body is provided with a socket, the socket can be in inserted fit with a spigot in an adjacent pipeline body, a first annular groove is formed in the outer wall of the spigot around the spigot, and a second annular groove is formed in the inner wall of the socket around the socket. A worker does not need to get into the pipeline for operation during sealing, and an adhesive only needs to be injected at an inlet of the outside of the pipeline body, so that the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of urban buildings, in particular to a drainage pipe and a construction method thereof. Background technique [0002] Urban underground drainage pipes are intricate. With the frequent drainage and aging of drainage pipes, the leakage of drainage pipes often occurs. Whether it is the waste of precious water resources or the various economic losses caused by the leakage of drainage pipes, the leakage of drainage pipes must be paid enough attention to. [0003] The Chinese patent whose publication number is CN104895174A discloses a construction method of a large-diameter rainwater and sewage pipeline assembly type component structure. The construction method mainly includes the following steps: construction preparation, pipe groove excavation, foundation leveling, cement solidification layer construction, pipe base hoisting, pipe installation, grouting closure construction, concrete backfill construction and g...
