Pre-stressed anchor cable structure and design and construction method thereof
The invention discloses a pre-stressed anchor cable structure and a design and construction method thereof.The pre-stressed anchor cable structure comprises an anchoring body, a retaining structure, a seamless steel pipe, an unbonded pre-stressed steel strand and a PVC grouting pipe, the anchoring body is horizontally arranged in filling soil in a theoretical fracture surface and is of a hollow cast-in-place structure or a hollow prefabricated structure, and the retaining structure is arranged in the hollow cast-in-place structure or the hollow prefabricated structure; a plurality of grouting holes are evenly formed in the periphery of the anchoring body, the PVC grouting pipe is arranged in the seamless steel pipe, one end of the PVC grouting pipe faces the anchoring body, and the other end of the PVC grouting pipe is arranged on the supporting and retaining structure. According to the pre-stressed anchor cable structure, the form of an anchoring body can become rich and diversified, the size is more flexible and changeable, different anchoring force requirements are met, and a series of problems that when a traditional pre-stressed anchor cable structure is applied to filling engineering, the anchoring body is small in diameter, low in anchoring force, prone to hole collapse, large in hole forming difficulty, prone to creep deformation and the like are solved.
本发明公开了一种预应力锚索结构及其设计施工方法，预应力锚索结构包括锚固体、支挡结构、无缝钢管、无粘结预应力钢绞线和PVC注浆管，锚固体水平设置在理论破裂面内的填土中，锚固体设置为中空现浇结构或中空预制结构，锚固体的四周均匀设置有若干注浆孔，PVC注浆管设置在无缝钢管中，PVC注浆管的一端朝向锚固体设置，PVC注浆管的另一端设置在支挡结构上，本申请中的锚固体无需特殊成孔设备，不受钻孔施工工艺限制，施工工艺更加简便，使锚固体的形式能够变得丰富多样，尺寸更加灵活多变，适应不同锚固力需求，解决了传统预应力锚索结构应用于填方工程中存在锚固体直径小、锚固力低、易塌孔成孔难度大、易发生蠕变变形等一系列问题。
