Non-excavation-type repairing construction technology of underground pipeline

Abstract

The invention discloses a non-excavation-type repairing construction technology of an underground pipeline and belongs to the field of underground pipeline repairing. According to the repairing construction technology of the underground pipeline, the underground pipeline can be repaired without workers entering the underground pipeline. The non-excavation-type repairing construction technology ischaracterized by comprising the following steps that S1, an epoxy resin curing agent is prepared; S2, a reinforced fabric is soaked through the epoxy resin curing agent; S3, the reinforced fabric, soaked by the epoxy resin curing agent, in the step S2 is wound on a pipeline repairing device; S4, the pipeline repairing device wound with the reinforced fabric is sent to the breakage of the underground pipeline, and the reinforced fabric adheres to the breakage of the underground pipeline; and S5, after the reinforced fabric is solidified at the breakage of the underground pipeline, the pipelinerepairing device is recovered.

Description

technical field [0001] The invention relates to the field of repairing underground pipelines, in particular to a non-excavation repairing construction technology for underground pipelines. Background technique [0002] Many pipelines buried underground are intersected and intricate. Some pipelines have been used for many years, and leakage and rupture accidents frequently occur. Most of these pipelines are laid in densely populated and commercially prosperous urban areas. Excavation construction will cause traffic Blockage, destruction of green spaces and gardens, and the process of excavating and repairing pipelines often cause damage to other pipelines. Some pipelines have small diameters and no working surfaces, so personnel cannot enter the pipelines to carry out repairs. There is another fatal problem with the pipelines in the city. Most of the underground pipelines are airtight, and there is a lot of deadly poisonous gas, and people cannot enter the pipeline network fo...
