Novel triangular net-hanging resistance-increasing anchor rod supporting device and construction method
The invention relates to improvement of a foundation pit slope rock-soil body supporting technology, in particular to a novel triangular hanging net resistance-increasing anchor rod supporting device and a construction method, which can effectively reduce the porosity of a foundation pit slope soil body, reduce the compressibility, increase the compactness and improve the bearing capacity and uplift bearing capacity of the soil body. The triangular net hanging anchor rods and a slope soil body form a compact and high-strength composite body; the elongation rate and the uplift bearing capacity of the anchor rod are effectively improved, damage caused by displacement deformation of a large soil body can be borne, and the slope stability is improved; which comprises an outer-layer anchor rod and is characterized in that a conical head is arranged at the bottom of the outer-layer anchor rod, the diameter of the conical head is larger than that of the outer-layer anchor rod, and a first resistance increasing device is arranged on the side wall of the outer-layer anchor rod; the inner-layer anchor rod is inserted into the outer-layer anchor rod through the limiting disc and is in sliding fit with the outer-layer anchor rod, the diameter of the outer-layer anchor rod is larger than that of the inner-layer anchor rod, and the outer-layer anchor rod and the inner-layer anchor rod are each of a hollow structure.
本发明涉及基坑边坡岩土体支护技术的改进，具体为一种新型三角形挂网增阻锚杆支护装置及施工方法，能够有效的减小基坑边坡土体孔隙率，降低压缩性，增大密实度，提高土体承载力和抗拔承载力，使得三角形挂网锚杆和边坡土体形成密实且强度较高的复合体；且有效提高锚杆延伸率和抗拔承载力，可承受大土体位移变形造成的破坏，提高边坡稳定性；包括外层锚杆，其特征在于，所述外层锚杆的底部设有圆锥形锥头，所述圆锥形锥头的锥头直径大于外层锚杆的杆径，外层锚杆的侧壁上设有增阻装置一，还包括内层锚杆，所述内层锚杆通过限位圆盘插接在外层锚杆内且与外层锚杆滑动配合，所述外层锚杆直径大于内层锚杆，所述外层锚杆和内层锚杆均为中空结构。
