Anchor rod grouting supporting device for soft soil slope and construction method
The invention provides an anchor rod grouting supporting device for a soft soil slope and a construction method in the technical field of slope protection construction.The anchor rod grouting supporting device comprises an outer sleeve, a conical head is fixed to one end of the outer sleeve, a center hole is formed in the center of the outer sleeve, an inner sleeve is inserted into the center hole, and the diameter of the cross section of the center hole is larger than that of the cross section of the inner sleeve; a core hole is formed in the center of the inner sleeve, and the inward end of the inner sleeve abuts against the conical head. The outer sleeve is provided with a plurality of grouting branch pipe holes which face the inner sleeve and obliquely extend in the direction away from the conical head, grouting branch pipes are arranged in the grouting branch pipe holes, the inward ends of the grouting branch pipes are provided with jacking balls, and grouting holes communicated with the grouting branch pipes are formed in the jacking balls. An arc-shaped groove matched with the jacking ball is formed in the outer wall of the inner sleeve in the length direction of the inner sleeve, a grouting hole communicated with the core hole is further formed in the inner sleeve, and the grouting hole is communicated with the core hole through the grouting hole; the slurry diffusion condition is good, the soil layer reinforcing effect is good, and safety is high.
本发明提供了边坡防护施工技术领域内的一种用于软土质边坡的锚杆注浆支护装置及施工方法，包括外套管，外套管的一端固定有锥头，外套管的中心开有中心孔，中心孔内插接有内套管，中心孔的横截面直径大于内套管的横截面直径，内套管的中心设有芯孔，内套管朝里的一端抵触在锥头上；外套管上设有若干个朝向内套管且远离锥头所在方向倾斜延伸的注浆支管孔，注浆支管孔内设有注浆支管，注浆支管向里的一端设有顶撑球，顶撑球上开有与注浆支管相连通的灌浆孔，内套管的外壁沿内套管长度方向设有与顶撑球匹配的弧形凹槽，内套管上还开有与芯孔相连通的注浆孔，灌浆孔经注浆孔与芯孔相连通；本发明浆液扩散情况好，土层加固效果好，安全性高。
