Auxiliary anchor cable secondary grouting method
The invention discloses an auxiliary anchor cable secondary grouting method which comprises the following steps: (1) a grouting pipe and an anchor cable correspondingly penetrate through a through hole of a flexible base plate, and the flexible base plate is pushed and pressed towards an anchor cable hole until the flexible base plate covers the periphery of the anchor cable hole; and (3) grouting is conducted on the anchor cable hole through a grouting pipe, in the process, a first slurry leakage hole and a second slurry leakage hole are concerned, when cement slurry overflows, it is indicated that the anchor cable hole is filled with slurry, at the moment, grouting is stopped, then the fixing plate and the flexible base plate are taken down, and grouting work is completed. Under the condition that normal work of the anchor cable and the grouting pipe is not affected, the hole opening of the foundation pit slope anchor cable hole can be blocked, whether the hole is filled with cement paste or not is judged through the grout leakage hole, and therefore secondary grouting work of the anchor cable hole reaches a primary overflow state, multiple times of grout supplementing work of conventional construction is avoided, and the construction efficiency is improved. And the secondary grouting efficiency of the anchor cable hole is greatly improved.
本发明公开了一种辅助锚索二次注浆方法，包括①将注浆管、锚索对应穿过柔性垫板的通孔，并将柔性垫板向锚索孔方向推压，直至柔性垫板覆盖在锚索孔周围②将固定板放置在柔性垫板上方，并向锚索孔方向推压固定③通过注浆管对锚索孔进行注浆，在此过程中，关注第一漏浆孔和第二漏浆孔，当有水泥浆溢出时，说明锚索孔已注满浆液，此时，停止注浆，然后将固定板和柔性垫板取下，完成注浆工作。本发明能够在不影响锚索和注浆管正常工作的情况下，实现对基坑边坡锚索孔的孔口封堵，并通过漏浆孔判断孔内是否注满水泥浆，从而使锚索孔二次注浆工作达到一次满溢状态，避免了常规施工的多次补浆工作，大大提高了锚索孔二次注浆效率。
