The invention discloses a pipeline detection and dredging non-excavation repair method. The method comprises the steps that the inner wall of a pipeline is detected so as to determine a to-be-repairedportion; the position, where the to-be-repaired portion is located, of the inner wall of the pipeline is dredged and cleaned; a pipeline non-excavation repair device is conveyed to the position, where the to-be-repaired portion is located, of the interior of the pipeline from an inspection well at one end of the pipeline where the to-be-repaired portion is located; and the to-be-repaired portionis repaired through the pipeline non-excavation repair device. By means of pipeline detection and dredging non-excavation repair method, the damaged pipeline can be repaired in a non-excavation mode,earth around the damaged pipeline does not need to be excavated deeply for taking out the damaged pipeline, the construction amount is small, the construction time is short, and accordingly, the construction cost for repairing the damaged pipeline is effectively saved.
Description
technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a non-excavation repair method for pipeline detection and dredging. Background technique [0002] Urban underground pipelines are one of the important infrastructures that support social development and ensure people's lives. Pipeline maintenance for underground pipelines is a necessary means to ensure their normal mechanism and function. With the extension of use time, underground pipelines will inevitably have problems of varying degrees of clogging and damage. It is necessary to regularly clean and maintain the environment inside the pipelines or replace damaged pipelines. Underground pipelines are buried deep below the ground, and repairs are required in case of damage Or when replacing, it is necessary to carry out deep excavation to take out the damaged pipeline, which requires a large amount of construction. Contents of the invention [0003] The present inventi...
