Embodiment Construction

[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] The invention provides a pipeline repair method, referring to Figure 1 to Figure 7 , in one embodiment, the pipeline repair method includes:

[0053] Step 1, refer to figure 1 , cleaning the inner wall of the pipeline 30 to be repaired;

[0054] Step 2, refer to figure 2 and image 3 , the steel bar 10 is inserted from one end of the first inner lining to the other end of the first inner lining, and one side of the first inner lining 20 is directed toward the first inner lining from one end of the first inner lining along the axial direction of the pipeline to be repaired. The other end of a liner is arranged with several support members 22, and the support member 22 is a frame body, and the steel bar 10 is inserted into the frame body.

[0055] Step three, refer to Figure 4 and Figure 5 , deploying ...

Abstract

The invention discloses a pipeline repairing method. During a pipeline repairing process, a steel bar is inserted into a first liner in a penetrating mode after a pipeline is cleaned, then the first liner with the inserted steel bar is placed in the pipeline to be repaired, the first liner and the inner wall of the pipeline are attached through an air bag, then grouting materials are injected into a gap formed between the inner wall of the pipeline and a liner plate of the first liner, and after the grouting materials are condensed, pipeline repairing is completed. According to the pipeline repairing method, the condensed grouting materials are grabbed through a supporting piece, the steel bar is inserted between the grouting materials in a penetrating mode, so that the intensity of the grouting materials is greatly improved, and the pressure-resisting capacity, the shock-resisting capacity, the distorting-resisting capacity, the impact-resisting capacity and the like of the repaired pipeline are improved as a whole substantially.

Description

technical field [0001] The invention relates to the field of pipeline repair, in particular to a pipeline repair method. Background technique [0002] Drainage pipes, canals, etc. are essential infrastructure in people's lives. If the pipes are used for a long time, they will be damaged by aging, corrosion, cracks, and collapses, which will adversely affect normal production and life. They need to be repaired in a timely manner. Make repairs. At present, the ideal method for pipeline repair is the lining method, that is, the lining pipe is placed in the pipeline to be repaired, and then the grouting material is injected between the inner wall of the pipeline to be repaired and the lining, and after the grouting material is solidified, the Completion of pipeline repair work. This pipeline repair method is only suitable for the repair of small pipelines or low-strength pipelines; for the repair of large pipelines, on the one hand, the pipeline reinforcement layer (grouting m...
