Expanding grouting pipe suitable for karst foundation pit
The invention provides an expansion body grouting pipe suitable for a karst foundation pit. The expansion body grouting pipe comprises a grouting pipe upper section, an expansion body and a grouting pipe lower section. A valve is arranged on the grouting pipe upper section; a containing cavity is formed in the expansion body, an opening in the upper end of the containing cavity is communicated with the upper section of the grouting pipe, and an opening in the lower end of the containing cavity is communicated with the lower section of the grouting pipe; the volume of the accommodating cavity can be adjusted and changed; a pressurizing ring is arranged on the peripheral side of the expansion body and communicated with a pressurizing device, and pressurizing fluid is filled in the pressurizing ring. According to the invention, the cavity expansion body is matched with the pressurizing ring and the pressurizing device, so that slurry can be uniformly distributed, and waste of the slurry is reduced; by arranging the valve, the flow of slurry can be accurately controlled, the cost and the resource loss are reduced, excessive pressure and related risks are reduced through the controllable flow, and a safer construction environment is provided; in addition, through cooperation of the expansion body, the pressurizing ring, the pressurizing device and the valve, grouting work can be completed more quickly, and time and resources are saved.
本发明提供一种适用于岩溶基坑的扩体注浆管，包括注浆管上段、扩体、注浆管下段；所述注浆管上段上设有阀门；所述扩体内具有容腔，容腔的上端开口与注浆管上段相连通，容腔的下端开口与注浆管下段相连通；所述容腔的体积可调节变化；所述扩体周侧设有加压圈，所述加压圈与加压装置相连通，所述加压圈内填充加压流体。本发明通过具有容腔扩体与加压圈、加压装置相配合，可以均匀分布浆料，减少浆料浪费；通过设置阀门，能够精确控制浆料的流量，降低成本和资源损耗，可控的流量减少了过度压力和相关的风险，提供了更安全的施工环境；此外，还可以通过扩体、加压圈、加压装置以及阀门之间的配合，更快地完成注浆工作，节省时间和资源。
