Foundation pit slope support fixing system and fixing method thereof
The invention discloses a foundation pit slope supporting and fixing system and a fixing method thereof. The supporting and fixing system comprises a fixing device and a drilling device. The fixing device comprises an anchoring body and an anchor cable, the anchoring body comprises a conical anchor head, one end of the anchor cable is rotatably connected with the rear side of the anchor head, the drilling device comprises a fixing frame and a guide plate on the upper side of the fixing frame, a driving box is slidably arranged on the guide plate, a front-back through hollow drilling barrel is rotatably arranged on the driving box, and the front end of the drilling barrel is connected with the rear side of the anchor head in an inserted and clamped mode. The anchor cable is positioned in the drill cylinder; a jetting head inserted into the column casing is arranged on the rear side of the driving box, a first spiral blade and a second spiral blade are arranged on the outer ring of the anchor head and the outer ring of the drilling cylinder correspondingly, and when the drilling cylinder drills holes, an anchoring body can be directly beaten into a side slope in cooperation with water injection work of the jetting head; when the drill cylinder retreats, the anchoring body can be left in the side slope, the anchoring device can be fixed through one-time drilling in cooperation with the grouting work of the jet head, the foundation pit supporting construction time is shortened, and the construction speed is remarkably increased.
一种基坑边坡支护固定系统及其固定方法，支护固定系统包括固定装置以及钻进装置；固定装置包括锚固体和锚索，其中锚固体包括锥形锚头，锚索一端与锚头后侧转动连接，钻进装置包括固定架及其上侧的导向板，导向板上滑动设有驱动箱，驱动箱上转动设有前后贯通的中空钻筒，钻筒前端与锚头后侧插接并卡接连接，锚索位于钻筒内；驱动箱后侧设有插入至柱筒内的喷注头，锚头和钻筒外圈分别设有第一螺旋叶和第二螺旋叶，钻筒钻孔时，配合喷注头的注水工作，能够直接将锚固体打入边坡内部；钻筒退出时，锚固体能够留在边坡内部，配合喷注头的注浆工作，一次钻孔既能够完成锚固装置的固定工作，缩短了基坑支护施工时间，显著提高了施工速度。
