Description
Technical Field
The utility model relates to a non-excavation drainage pipe slip casting prosthetic devices.
Background
When underground pipelines such as underground sewer pipelines, industrial water pipelines and tap water pipelines are damaged, in order to repair the damaged section of the underground pipeline, the ground of the damaged section of the underground pipeline is usually excavated, and then the damaged section of the underground pipeline is replaced. However, the excavation repair technology has the defects of traffic influence, disturbance of residents, long construction period, high construction cost, great social influence and the like. Therefore, the trenchless repairing technology is preferred for pipeline repairing in the market at present, and because the trenchless repairing technology is used for underground closed space operation, the trenchless repairing technology has the advantages of small traffic influence, short construction period, small social influence, reasonable manufacturing cost and the like. Specifically, aiming at the defects of pipeline disjointing, staggered joint, damage, leakage and the like at present, the repair methods such as spraying, grouting, local or integral lining and the like are generally adopted for treatment. However, during spray repair, since the spray repair is performed on a normal pressure or an open working surface, it is difficult to achieve full space filling of the repair material for the defective position of the pipeline and to ensure the full compactness; especially, before repairing a local or whole lining of a small-diameter pipeline, the pipe diameter is too small, grouting filling or water stop pretreatment cannot be carried out on defects, and then in the process of repairing the local or whole lining and the like, the problem that repair materials are easily washed by water (such as leakage water) in the pipeline is solved, and in addition, a larger gap still exists in the defect position wrapped by the repair materials after the repair is finished. In addition, when the conventional grouting water stopping repair is carried out, grouting holes need to be arranged on the pipe wall, and the grouting holes need to damage the pipeline structure.
The patent with publication number CN109595425A discloses a pipeline repairing device and method, which comprises inflating an annular air bag to make the outer annular wall of the annular air bag closely fit with the pipe wall of the pipeline, and injecting repairing material into the defect position of the pipeline from a grouting hole. However, although the annular air bag can perform spot repair, the annular air bag cannot reinforce the damaged rock-soil layer on the outer wall of the pipeline, and if the rock-soil layer is continuously damaged, the repaired pipeline section may be damaged again. And when a certain section of position on the pipeline is damaged at multiple positions, the annular air bag can not be repaired at the same time. In addition, the existing pipeline repairing needs to be operated after water drainage, and the influence is large.
