Pipeline repairing method

Abstract

The invention discloses a pipeline repairing method. The method comprises the following steps of step1, detecting water quality of sewage around a leakage point of a pipeline, and detecting whether the water quality is harmful; step2, after the water quality is confirmed to be harmless, entering into water to explore a position and a size of the pipeline leakage point; step3, eliminating sludge ona surface of the pipeline till that a bottom of the pipeline is exposed; and step4, installing the pipeline repairing device at the pipeline leakage point. By using the pipeline repairing method, time for reporting and going through a process when a traditional pressure pipeline needs to be repaired is saved, procedures that related departments command a sewage plant to stop water supply according to a minimum time period of a citizen water flow, then water pumping repairing is performed and so on are saved too, and a whole repairing period is short. The repairing period is short, repairing cost is low, a social negative influence is small, and normal water use of surrounding residents is not influenced.

Description

technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a pipeline repair method. Background technique [0002] In pipeline construction, especially in municipal pipeline construction, it is common for new pipelines to pass through existing pipelines or connect new pipelines to existing pipelines. Once the original sewage pipeline is damaged, the sewage will flow out rapidly and continuously under the pressure, and it will be difficult to drain the sewage and dry construction cannot be formed. At present, the construction can only be carried out by contacting the relevant government departments to coordinate and arrange the upstream or downstream sewage plants to suspend production, and then drain the sewage to form a dry construction environment. In this way, not only will the construction period be affected due to the long repair period, but also the compensation for the shutdown of the sewage plant will be made. In more se...

Problems solved by technology

In this way, not only will the construction period be affected due to the long repair period, but also the compensation for the shutdown of the sewage plant will be made. In more serious cases, it will affect the normal living water of the surrounding residents and cause greater losses.
