Dredging and desilting method for pipelines

Abstract

The invention relates to a dredging and desilting method for pipelines, and relates to the technical field of pipeline cleaning. The method solves the problem that sludge and waste accumulating in a pipeline for a long time can produce toxic gas, and when construction personnel work in the pipeline for a long time, the body of the personnel can be injured, resulting in certain hidden safety hazards. The method comprises the steps of S1, transporting two inflatable plugging pieces into the pipelines; S2, filling the two inflatable plugging pieces to seal the pipelines between the two inflatableplugging pieces; S3, injecting clean water into the pipelines between the two inflatable plugging pieces through a water injection and pumping assembly to dilute the sludge; S4, extracting mud watermixture between the two inflatable plugging pieces; and S5, pulling out the inflatable plugging pieces with a traction assembly to take out left inner wall residue of the pipelines. The method has theeffects of no need for the construction personnel to work in the pipelines for a long time, and improving the safety of pipeline dredging.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a pipeline dredging and desilting method. Background technique [0002] Pipeline dredging refers to dredging the pipeline, cleaning up the silt and other wastes in the pipeline, and keeping it unblocked for a long time to prevent urban waterlogging. If the pipeline is not regularly dredged, it will cause excessive sewage flow, pollute the environment, and bring troubles to people's lives. [0003] In the prior art, the dredging of the inner wall of the pipeline is generally carried out by manual dredging of the inner wall of the pipeline of the water conservancy project, and the sludge waste in the pipeline will generate toxic gas if it accumulates for a long time. When the construction personnel work in the pipeline for a long time, it will cause Cause physical damage, there is certain potential safety hazard, and there is still room for improvement.
