Recyclable pre-stressed anchor cable for foundation pit supporting and construction method thereof
The invention relates to the technical field of foundation pit supporting, in particular to a recoverable pre-stressed anchor cable for foundation pit supporting and a construction method of the recoverable pre-stressed anchor cable. The device is composed of a steel strand, a PVC sleeve, a fixed end separable anchor plate, an elastic rubber ring, a fixed end extrusion head, a conical opening breaking device, a grouting pipe, a prestress device and an anchorage device. During assembly, the conical breaking device and the grouting pipe (the grouting pipe is fixed in the middle of the hollow conical breaking device, the joint is sealed, and slurry is prevented from entering the hollow conical breaking device) penetrate into the separable anchor plate which is tightly sleeved by the elastic rubber ring, and the diameter of the elastic rubber ring is slightly smaller than that of the anchor plate, so that the separable anchor plate is tightly hooped when the steel strand is tensioned. After the steel strand continues to penetrate through the separable anchor plate at the fixed end, the extrusion head is manufactured through the extrusion equipment and the extrusion sleeve, and at the moment, manufacturing of the anchor head mechanism at the fixed end of the anchor cable is completed.
本发明涉及基坑支护技术领域，具体是一种用于基坑支护的可回收预应力锚索及其施工方法。本发明由钢绞线、PVC套管、固定端可分离式锚板、弹性橡胶圈、固定端挤压头、锥形破口器、注浆管、预应力及锚具组成。组装时，将锥形破口器、注浆管（注浆管固定在空心锥形破口器中间，相接处密封，防止浆体进入空心锥形破口器）穿进由弹性橡胶圈套紧的可分离式锚板，此弹性橡胶圈的直径较锚板稍小，得以在张拉钢绞线时紧箍可分离式锚板。继续将钢绞线穿过固定端的可分离式锚板后采用挤压设备和挤压套制作挤压头，此时锚索固定端锚头机构完成制作。
