High-pressure jet grouting anchor cable end, drilling tool and construction method
The invention provides a high-pressure jet grouting anchor cable end, a drilling tool and a construction method, and belongs to the technical field of deep foundation pit construction supporting, the high-pressure jet grouting anchor cable end comprises an anchor disc, an anchor cable and a sleeve, a via hole is formed in the middle of the anchor disc, and anchor cable holes are formed in the periphery of the anchor disc; the multiple anchor cables are arranged in the anchor cable holes correspondingly. The sleeve is arranged in the via hole, the interior of the sleeve is suitable for a drill bit to penetrate through, steel sheet assemblies are arranged at the two ends of the sleeve, each steel sheet assembly comprises a fixing part and a plurality of steel sheets, the first ends of the steel sheets are fixedly connected with the sleeve, and the fixing parts are arranged at the second ends of the steel sheets so as to fix the steel sheets; when the drill bit sprays slurry, slurry flowing through the steel sheet assembly can damage the fixing piece, and the multiple steel sheets are unfolded outwards. When the end of the high-pressure jet grouting anchor cable provided by the invention is subjected to slurry spraying, the slurry bursts open the steel sheet, the steel sheet is unfolded and the steel sheet is inserted into the slurry, so that the reinforcing and fixing effects are achieved, the anchor cable is more stable in the slurry spraying process, the anchoring capacity is further improved, the structure is simple, and the reinforcing mode is convenient and rapid.
本发明提供一种高压旋喷锚索端头、钻具及施工方法，属于深基坑施工支护技术领域，包括锚盘、锚索和套管，锚盘的中部设置有过孔，锚盘的四周设置有锚索孔；锚索具有多个，分别设置在锚索孔中；套管设置在过孔中，套管内部适于钻头穿过，套管两端均设置有钢片组件，钢片组件包括固定件和多个钢片，钢片的第一端与套管固定连接，固定件设置在钢片的第二端处，以固定多条钢片；钻头进行喷浆时，流经钢片组件的浆液能够破坏固定件，且使得多个钢片向外展开。本发明提供的高压旋喷锚索端头喷浆时浆液将钢片冲开，钢片展开，钢片插入泥浆中，起到了加固固定的作用，使得喷浆过程中锚索更加稳定，且进一步提高了锚固能力，结构简单，加固方式方便快捷。
