The invention relates to a grouting repair method for a pipeline lining. The method comprises the steps that S1, the position and the specification size of a to-be-repaired pipeline are determined; S2, a corresponding lining pipe is manufactured according to the specification size and a pressure bearing condition of the to-be-repaired pipeline; S3, expansion sealing devices are additionally arranged at the two ends of the lining pipe; S4, the to-be-repaired pipeline is cut off at the proper positions of the two ends of a damaged and aged position; S5, the manufactured lining pipe is put into the to-be-repaired pipeline, and annular gaps between the two ends of the end opening of the to-be-repaired pipeline and the two ends of the end opening of the lining pipe are blocked through a blocking material; S6, after the blocking material at the two ends is solidified, waterproof reinforcing slurry is injected into a pipe wall gap between the to-be-repaired pipeline and the lining pipe; and S7, after the waterproof reinforcing slurry is solidified, the originally-broken pipeline is connected, and repairing of the damaged or aged pipeline is completed. The method is low in cost and good in maintenance effect, and solves the problem of repair of a pipeline which is difficult to excavate.
Description
technical field [0001] The invention relates to the field of pipeline repair, in particular to a pipeline lining grouting repair method. Background technique [0002] When deep underground pipelines or pipelines in special locations are aging or damaged, pipeline repairs are required. The traditional method is to excavate the original pipeline location to replace or repair the pipeline. The disadvantage is that the excavation is difficult and costly, or there is no excavation Construction work surface. In this construction technology, a liner is installed in the original pipeline and then plugged by grouting, so as to achieve the purpose of repairing the damaged and aging pipeline. The problems of difficult excavation and high repair costs are solved. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method for repairing pipeline lining by grouting that overcomes the above problems or at least partially solve...
