Prestressed anchoring hole structure
The invention relates to a prestressed anchoring hole structure which comprises an anchoring cavity, a plurality of anchor cable fixing holes are drilled in a stable rock mass in the anchoring cavity, and a plurality of prestressed anchor cables are arranged in the anchoring cavity, one ends of the prestressed anchor cables are connected with the anchor cable fixing holes of the stable rock mass, and the other ends of the prestressed anchor cables are connected with anchor piers outside the anchoring cavity. A drainage hole is pre-formed in the position of a sliding zone in the anchoring cavern; a drainage hole is formed in the external anchorage pier, an anchor head of the pre-stressed anchor cable is fixedly connected with the external anchorage pier, a steel structure frame composed of longitudinal main reinforcements and transverse stirrups is arranged in the anchoring cavern, and the anchoring cavern is filled with concrete. The method has the beneficial effects that reinforced concrete is used for pouring the anchoring cavern, a plurality of pre-stressed anchor cables are arranged in the depth direction of the anchoring cavern, rock-soil bodies of a fragmentation structure and a discrete structure in the large side slope are replaced, and underground water in the slope body can be effectively discharged, so that the effects of large section, high pre-stress and deep reinforcement are achieved.
本发明涉及一种预应力锚固洞结构，包括锚固洞室，在锚固洞洞室内的稳定岩体上钻多个锚索固定孔，在锚固洞室内设有多根一端与稳定岩体的锚索固定孔连接，另一端与锚固洞室外部的锚墩连接的预应力锚索；在锚固洞室内滑动带的位置预设泄水孔；外部锚墩内设有排水孔，预应力锚索的锚头与所述外部锚墩固定连接，在所述锚固洞室内设有由纵向主筋和横向箍筋组成的钢结构架，并在锚固洞室内填充混凝土。其有益效果：使用钢筋混凝土对锚固洞室进行浇筑，并沿锚固洞室深度方向设置多根预应力锚索，置换了大型边坡中碎裂结构和散体结构的岩土体，并能够有效排出坡体内部的地下水，从而实现大截面、高预应力、深层加固的功效。
