Combined construction method of rotary spraying anchor cable construction process
The invention discloses a combined construction method of a rotary spraying anchor cable construction process. The combined construction method comprises the following steps that guide hole construction is performed after paying-off construction is completed; a rotary spraying type grouting drill bit with an anchor cable and an anchor ring is provided, the anchor ring is arranged on the rotary spraying type grouting drill bit in a sleeving mode, and the front end of the anchor cable is fixed to the anchor ring; and the rotary spraying type grouting drill bit drives the anchor cable and the anchor ring to enter a guide hole, and rotary spraying grouting drilling is conducted till the anchor cable is constructed to a designed depth. According to the construction method, the rotary spraying type grouting drill bit drives the anchor ring and the anchor cable to continuously rotate and go deep, and the hole collapse risk existing in anchor cable placement construction after traditional drilling is completed is avoided; according to the rotary spraying type grouting drill bit, a front-end rotating part can be used for drilling, and a rear-end fixing part is used for clamping the anchor ring and the anchor cable; the anchor ring is mainly used for integrating three strands of anchor cables together, so that the drill bit can be integrally brought in conveniently; and after the anchor cable penetrates through the anchor ring, the end of the anchor cable is widened, and the anchor ring can be firmly clamped by the anchor ring.
本发明公开了一种旋喷锚索施工工艺组合施工方法,其包括:放线施工完成后进行引孔施工;提供带有锚索和锚环的旋喷式注浆钻头,锚环套设于旋喷式注浆钻头上,锚索的前端固定于锚环上;旋喷式注浆钻头带着锚索和锚环进入引孔,进行旋喷注浆钻孔,直至锚索施工至设计深度。该施工方法端部由旋喷式注浆钻头,带动锚环以及锚索不断转动深入,避免了传统的钻孔完成之后再进行锚索放置施工中存在的塌孔风险;旋喷式注浆钻头,前端转动部分可用于钻进,后端固定部分用于卡住锚环以及锚索;锚环,主要用于将三股锚索整合到一起,方便钻头整体带入;锚索,待锚索穿过锚环之后,将锚索端部拓宽处理,方便锚环能够牢固的卡住锚环。
