Non-excavation repairing method for defects in large-pipe-diameter drainage pipeline
The invention belongs to the technical field of drainage pipeline repairing, and particularly relates to a non-excavation repairing method for defects in a large-pipe-diameter drainage pipeline. Comprising the steps of prefabricating a steel formwork, plugging and guiding water in a drainage pipeline, dredging and detecting the interior of the pipeline, conducting ventilation testing, enabling constructors to go down a well for operation, chiseling defect positions, cleaning and removing loose parts and garbage, brushing a concrete interface agent, positioning, installing and fastening the steel formwork, connecting a grouting pipe and grouting equipment, preparing a grouting material, and then conducting pressure grouting. The method for repairing the defects in the drainage pipeline has the advantages that the grouting technology is applied to repairing of the defects in the drainage pipeline, the repairing quality is improved, and the manufacturing cost is saved.
本发明属于排水管道修复技术领域，具体涉及一种针对大管径排水管道内缺陷的非开挖修复方法，包括预制钢模板、排水管道堵水导水、管道内清淤并检测、通风测试、施工人员下井作业、缺陷处凿毛处理、清理并清除松动部分和垃圾、涂刷混凝土界面剂、钢模板定位安装及紧固、连接注浆管及灌浆设备以及配制灌浆料，之后压力注浆，待灌浆料终凝30min后拆除钢模板，清理现场，本发明的有益效果为：使注浆技术应用于排水管道内缺陷的修复中，提高修补质量，节约造价。
