Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipe repair, in particular to a grouting structure for sewage pipe repair. Background Art

[0002] Due to the large amount of corrosive gases in sewage pipes and improper operation and maintenance, concrete pipes and canals have serious corrosion, leakage and other defects, which not only affect the normal drainage function of the pipes and canals, but also easily lead to accidents such as ground collapse. At present, there are two main types of repairs for damaged pipes: one is the excavation-based pipe repair technology, which is suitable for sites with serious misalignment or serious sinking of pipes, low population density, wide construction sites, and relatively small impact on traffic; the other is the trenchless pipe repair technology, which is suitable for sites with less serious misalignment or sinking of pipes, line leakage in pipes, cracks in interfaces, urban center areas, and sites where excavation seriously affects traffic. Among them, the trenchless repair technology has the advantages of small negative impact on repair, less occupied site, and very weak impact on the ground, traffic, environment, and surrounding underground pipelines, etc., and is increasingly valued by the management departments of the underground pipeline industry.

[0003] The existing grouting structure for repairing sewage pipes is not convenient to be fixed on the pipes that need to be repaired, and holes need to be drilled to fix them. The drilling itself will cause damage to the pipes, and the position of the grouting head cannot be adjusted according to the position of the grouting. It is not flexible enough to use. Therefore, the utility model proposes a grouting structure for repairing sewage pipes to solve the above problems. Utility Model Content
