Non-excavation dredging and repairing construction method for drainage pipeline
The invention discloses a drainage pipeline trenchless desilting and repairing construction method, and belongs to the technical field of pipeline repairing. The method is realized through seven steps of pipeline plugging, pipeline diversion dewatering, pipeline temporary drainage dewatering, pipeline dredging, pipeline special cleaning and well chamber cleaning, pipeline foreign matter removal and trenchless repair. According to the air bag plugging method, rubber air bags are installed on the upstream and the downstream of the cleaning area section for plugging, all water inlet sources are cut off, corresponding water levels are controlled, water head pressure is reduced, and operation safety is improved. The temporary drainage pipeline is erected, water is pumped into the temporary pipeline through the water pump to be drained into the downstream well, and therefore the requirement for no water or little water in the pipeline can be met, and pipeline detection is facilitated. According to the method, the alkali-free glass fiber hose is adopted, the alkali-free glass fiber hose is pulled into the to-be-repaired pipeline from the inspection well after being fully soaked in the resin, the hose is expanded to be round through air pressure, and a firm and smooth new lining pipe is formed after ultraviolet light curing, so that the repairing purpose is achieved.
本发明公开了一种排水管道非开挖清淤、修复施工方法，属于管道修复技术领域。本发明通过管道封堵、管道导流降水、管道临排降水、管道清疏、管道特殊清理及井室清理、管道异物清除和非开挖修复这七个步骤予以实现。本发明气囊封堵法在清洗区域段上游下游各安装橡胶气囊进行封堵，截断所有进水源，控制相应水位，降低水头压力，提高作业安全性。本发明通过架设临时排水管线，用水泵把水抽到临时管线内排到下游井中，从而可实现管内无水或少水的要求，便于检测管道。本发明采用无碱玻璃纤维软管，经树脂充分浸渍后，从检查井处拉入待修复管道中，用气压将软管涨圆，紫外光固化后形成一条坚固光滑的新内衬管，达到修复的目的。
