Trenchless pipeline damage repairing device and repairing method
Technical Field
The invention relates to the technical field of pipeline repair, in particular to a device and a method for repairing damage of a trenchless pipeline.
Background
The ultraviolet light curing pipeline repairing technology is one of in-situ curing technologies. In the repairing process, the glass fiber permeated with resin is pulled into the pipe orifice at two closed ends of the pipe to be repaired from an inspection wellhead by professional personnel and equipment, compressed air is filled in the glass fiber lining pipe, and then the ultraviolet vehicle automatic control equipment is adopted for irradiation. The purpose of repairing the pipeline can be achieved by only using 3-4 hours under strict control, and the seals at two ends of the glass fiber pipe are cut off, so that the pipeline can normally drain water.
Ultraviolet curing repair principle: the ultraviolet light curing is to use ultraviolet light as a curing medium, the resin contains a photoinitiator, and when the resin is irradiated by the ultraviolet light with specific wavelength, the resin generates a curing reaction to form a new high-strength lining tube.
However, in the existing ultraviolet ray repairing device, firstly, two times of punching are performed on the repairing hose to ensure that the repairing hose abuts against the inner wall of the pipeline, the first time of pressurizing is used for introducing lighting equipment, and the second time of pressurizing is used for ensuring that the hose abuts against the inner wall of the pipeline after the lighting equipment is introduced, but the effect of abutting against the inner wall of the pipeline by the repairing hose is poor due to the pressurizing state, so that improvement is needed, and unnecessary secondary pressurizing is reduced.
