Ultraviolet lamp light curing pipeline repairing method

Abstract

The invention relates to an ultraviolet lamp light curing pipeline repairing method, and relates to the technical field of municipal pipeline repairing. The method comprises the steps of S1, investigating and detecting, specifically, old pipeline data and positions are determined and a pipeline lining is prepared; S2, ventilating and cleaning, specifically, an old pipeline is cleaned twice; S3, cleaning detection, specifically, the inner wall of the cleaned pipeline is determined by adopting a pipeline CCTV television camera detection system; S4, pulling in operation, specifically, the pipeline lining is pulled into the old pipeline; S5, inflating operation, specifically, the pipeline inner lining is inflated and expand around, and the pipeline lining is tightly adhered the inner wall of the old pipeline to form an integrated pipe-in-pipe structure; S6, curing, specifically, irradiating and curing are carried out on the the pipeline lining by using an ultraviolet lamp; S7, repairing and detecting, specifically, a new pipeline is detected by adopting the CCTV television camera detection system; and S8, post-treatment and pavement restoration. According to the repairing operation method of the ultraviolet curing pipeline lining, the pipeline lining is cured on the inner wall of the old pipeline, the old pipeline does not need to be replaced or the road surface is excavated, and the purpose of trenchless repairing of municipal pipelines is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal pipeline repair, in particular to a pipeline repair method cured by ultraviolet light. Background technique [0002] Along with the construction of urban transportation facilities such as roads, bridges and underground rail transit, drainage facilities and municipal pipeline repair technologies for protecting the water quality of public waters and urban public environments have also been greatly developed. [0003] In the construction and maintenance of urban infrastructure, phenomena such as rupture of underground pipelines, disengagement of pipeline joints, and leakage of groundwater will be found, which will cause road subsidence and even collapse, affecting traffic and normal municipal drainage. Usually, it is necessary to use excavation repair technology to repair the pipeline, that is, excavate the exposed pipeline on the ground, and complete the repair work by repairing or even replacing ...
