Embodiment Construction

[0039] The following is attached Figure 1-5 The application is described in further detail.

[0040] The embodiment of the present application discloses a construction method for repairing the lining of a drainage pipe.

[0041] refer to figure 1 , The construction method for repairing the lining of the drainage pipe comprises the following steps:

[0042] Excavation of operation well 1.

[0043] Detect the original pipeline and determine all the damaged parts of the original pipeline to determine the length and position of the repaired pipeline 10 . The operation well 1 is dug underground from the ground, and the operation well 1 is vertically arranged. There are two operation wells 1, which are respectively placed at the two ends of the repair pipeline 10. The elevation of the operation well 1 bottom is 50-70cm lower than the bottom of the pipeline. The two ends of the repaired pipeline 10 are cut, the repaired pipeline 10 is separated from the original pipeline, and th...

Abstract

The present application relates to the field of drainage pipeline repair, in particular to a drainage pipeline lining repair construction method, which includes the following steps: excavating an operation well, detecting the damage of the original pipeline, determining the location of the repair pipeline, and opening Operate the well; cut both ends of the repaired pipe to separate the repaired pipe from the original pipe; clean the repaired pipe; fold the lined pipe radially, pass through the repaired pipe, and protrude out of the repaired pipe The lined pipes at both ends are cut off; the expansion of the lined pipe is restored to the initial directness, at this time, the outer wall of the lined pipe is in contact with the inner wall of the repaired pipe; the repaired pipe is connected to the original pipe, and the operation well is backfilled. The application has the effect of reducing the ground excavation area during pipeline repair.

Description

technical field [0001] The application relates to the field of drainage pipeline repair, in particular to a construction method for repairing the inner lining of the drainage pipeline. Background technique [0002] Underground pipelines are pipelines laid underground for transporting liquids or gases. Underground pipes for drainage usually use large-diameter seamless steel pipes to form continuous pipes by welding. After the underground pipeline has been used for a long time, due to various factors such as the underground environment and ground pressure, the pipeline will crack, and the groundwater and groundwater will flow into the pipeline with the soil and mud around the pipeline, and flow away with the sewage. If things go on like this, it will cause malignant circulation, eventually leading to the subsidence of ground buildings and roads. [0003] In the related art, when the damaged pipeline is repaired, the ground needs to be excavated to repair the position of the ...
