Grouting water guide leaking stoppage structure and underwater rotary jet grouting anchor cable waterstop construction method
The invention discloses a grouting water guide leaking stoppage structure and an underwater rotary jet grouting anchor cable waterstop construction method. The grouting water guide leaking stoppage structure comprises a blockage filling material, a water guide pipe, a grouting pipe, a rapid hardening filling material and a grouting waterstop material, the blockage filling material is mounted in arotary jet grouting anchor hole, the water guide pipe is embedded on the connecting position of an anchor hole waterstop curtain and a supporting pile, the grouting pipe is embedded in the anchor holewaterstop curtain, the end of the grouting pipe is subjected to seal leaking stoppage, the outer side of the grouting pipe is bound with a netted pressure-resisting hose used for first-time and second-time grouting, a water draining ditch with a gradient is excavated in the lower side of a foundation pit, the water guide pipe communicates with the water draining ditch, multiple water collecting ponds distributed on different positions are mounted in the water draining ditch, and are connected with a sewage sedimentation tank through pipelines, the rapid hardening filling material is subjectedto micro expansion solidifying in the rotary jet grouting anchor hole to achieve blockage, the grouting waterstop material is used for carrying out blockage during grouting operation, after an anchorcable is tensioned, the grouting waterstop material is used for carrying out second-time grouting blockage, the leaking stoppage effect is good, and operation is easy and convenient.
一种注浆导水堵漏结构及水下旋喷锚索止水施工方法，注浆导水堵漏结构包括封堵填充材料、导水管、注浆管、速凝填充材料以及注浆止水材料；封堵填充材料设置在旋喷锚孔内，导水管埋设在锚孔止水帷幕与支护桩交接处，注浆管埋设在锚孔止水帷幕当中，注浆管的尽头进行密封止漏，注浆管的外侧绑扎有用于第一次和第二次注浆的网文耐压软管；基坑下侧开挖带有坡度的排水沟，导水管连通排水沟，排水沟中设置有若干个分布在不同位置的集水池，集水池通过管道连接污水沉淀池；速凝填充材料通过在旋喷锚孔内微膨胀凝固实现封堵，注浆止水材料用于在注浆操作时进行封堵，当锚索张拉完成后采用注浆止水材料进行第二次注浆封堵。本发明堵漏效果好，操作简便。
