Embodiment Construction

[0025] In actual projects, for example, the municipal pipeline of Xiaoyuhe Road in Kunshan City has a length of 192m, no well chamber in the middle, a diameter of 800mm, and a buried depth of about 9m. It is close to the river, and the water level in the river is about 1.2m down from the road. There is a water leakage point near the top of the pipeline on the side of the river, 108.5m away from the upstream well chamber. The surface of the pipeline at the leaking point was seriously damaged, forming an irregular circle with a diameter of about 20cm, and there was a jet of water with a diameter of about 9cm. Since this section is the main traffic road with a large traffic flow and it is close to the river, it does not have the conditions for excavation and repair. It was decided to use ultraviolet light curing for the whole tube repair. Before the lined hose is put into the pipeline, the leak point needs to be plugged.

Abstract

The invention discloses a construction method for repairing an underground pipeline, and belongs to the field of municipal engineering construction. The construction method for repairing the underground pipeline comprises a CCTV monitor, a pipeline desilting device and ultraviolet curing equipment and further comprises the steps of traffic diversion setting, pipeline ventilation, upstream and downstream inspection well two-end plugging, pipeline desilting, CCTV detection, water leakage point plugging, lining hose pulling-in, hose ultraviolet curing, road recovery and the like. According to the construction method for repairing the underground pipeline, the whole pipeline is repaired through ultraviolet light curing, and the problem that excavation and repairing cannot be directly conducted when the pipeline leaks water in a special section is solved.

Description

technical field [0001] The invention relates to the field of municipal engineering construction, in particular to a construction method for repairing underground pipelines. Background technique [0002] In the municipal pipelines in some major areas, if there is a water leakage point on the top of the pipe near the river, it is difficult to repair the water leakage point at this time, because the water leakage point there is not suitable for excavation. Due to the construction conditions of the repair, it is impossible to directly repair the leaking point. Contents of the invention [0003] In order to overcome the defects of the existing technology, the technical problem to be solved by the present invention is to propose a construction method for repairing underground pipelines, which can be repaired by ultraviolet light curing the whole pipe, so as to solve the situation that the pipeline in this area cannot be directly excavated and repaired when the pipeline leaks. ...
