Technical Field
[0001] The utility model belongs to the technical field of rainwater pipe repair, and in particular relates to a local resin curing trenchless repair system for a rainwater pipe. Background Art
[0002] Pipeline rupture and collapse seriously affect the safe operation of urban drainage and pose a safety hazard to the lives of surrounding residents. Therefore, timely repair of pipelines is of great significance. From the perspective of safety and environmental impact and social and economic benefits, this plan uses advanced CCTV endoscopy detection technology to detect defects such as pipeline rupture and collapse. However, when repairing rainwater pipes traditionally, large-scale road closures and excavations are required on the road section, which affects the normal traffic of the road section and increases the repair cost of the rainwater pipe and reduces work efficiency. Therefore, a local resin curing trenchless repair system for rainwater pipes is proposed.
[0003] For example, a Chinese patent with publication number CN218671179U discloses a special area repair structure of an LNG pipeline insulation system, which is located in a special area of the LNG pipeline insulation system, and the special area includes the area where the valves and elbows of the pipeline are located. The special area repair structure includes a valve insulation substructure, an elbow insulation substructure and a straight pipe connection insulation substructure. The valve insulation substructure includes a valve insulation inner layer and a valve insulation outer layer sequentially coated on the outside of the valve from the inside to the outside, the valve insulation outer layer includes a prefabricated circular perforated aerogel block, a valve stem outer layer aerogel blanket, a valve body outer layer prefabricated aerogel blanket and a straight pipe flange aerogel blanket, and the elbow insulation substructure sequentially coats the elbow inner layer prefabricated aerogel blanket, the elbow middle layer prefabricated aerogel blanket, aluminum foil, the elbow outer layer prefabricated aerogel blanket and the main moisture-proof layer on the outside of the elbow from the inside to the outside.

In addition, when repairing ordinary rainwater pipes, the repair resin needs to be heated, which will cause secondary thermal damage to the inner wall of the pipe, resulting in a reduction in the service life of the pipe. In view of this, we propose a local resin curing trenchless repair system for rainwater pipes. Utility Model Content
