Abstract

The invention relates to the technical field of pipeline repair, in particular to a pipeline lining repair construction method. The invention includes S1 construction preparation, S2 pipeline pretreatment, S3 lining pipeline assembly, S4 deployment and filling slurry, S5 pipeline filling grouting, S6 detection, S7 air-tight test and other construction steps. By filling the slurry between the repaired pipeline and the lined pipeline, the new and old pipelines are integrated to achieve the purpose of repairing pipeline damage, which can greatly solve the damage problems such as corrosion, holes, and cracks in the pipeline. During the construction process, there is no need to intercept and block the repaired pipelines, and construction can be carried out while draining water, which can reduce the impact of construction on the use of the entire pipeline network and reduce construction costs. Moreover, the lined pipeline is formed by assembling the modular boards in stages, so the construction method of the present invention is applicable to the repair construction of straight pipelines, curved pipelines, and partial pipelines.

Description

technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a pipeline lining repair construction method. Background technique [0002] For serious leakage problems in water supply, drainage and other pipelines, the pipelines are generally repaired. [0003] Existing pipeline repair methods usually include composite material lining method, coating lining method, stainless steel lining method and so on. [0004] Composite material lining method: the composite material (pasted and fixed on the inner wall of the original concrete pipe as the inner lining, and is closely attached to the original pipe to form a composite structural pipe. [0005] Coating lining method (spraying lining method): use air as the power source to spray polymers (mainly polymerized cement mortar, epoxy mortar, polyurethane, polyethylene, etc.) The thickness of the inner lining layer is formed after curing. [0006] Lined stainless steel method: the stainle...
