Composite detachable anchor cable supporting structure and construction process thereof
The invention discloses a composite detachable anchor cable supporting structure and a construction technology thereof, and relates to the technical field of anchor cable supporting, the supporting structure comprises an anchor hole, a composite anchor cable and a pressure-bearing seat, the anchor cable comprises an anchor head and a plurality of anchor cable bundles, the anchor head at the tail end of each anchor cable bundle is inserted into the bottom of the anchor hole, and the pressure-bearing seat is inserted into the anchor hole; the anchor cable bundle penetrates through the pressure-bearing seat, is arranged in the anchor hole and is fixed on the outer surface of the soil body through the pressure-bearing seat; and a fuse connected with a power supply is arranged in an anchor locking hole in the middle of the anchor head. During construction, a T-shaped anchor hole is drilled in a soil body through a drilling machine, an anchor head is inserted into the bottom of the anchor hole, and an anchor cable bundle is connected with a pressure-bearing seat; cement paste is injected into the anchor holes and cured until the compressive strength reaches a specified value, and then all the anchor cable bundles are tensioned in a graded mode without displacement; the elongation change of the anchor cable bundle is monitored through a pressure sensor on the pressure-bearing seat; after construction, the fuse is electrified and melted to enable the anchor head to fall off, and the anchor cable bundle is recycled. The method has the advantages of being easy and convenient to construct, convenient to recycle, large in bearing capacity, low in cost and small in underground pollution.
本发明公开了一种复合型可拆卸锚索支护结构及其施工工艺，涉及锚索支护技术领域，支护结构包括锚孔、复合型锚索及承压座，锚索包括锚头和若干个锚索束，锚索束末端锚头插入锚孔底部，锚索束贯穿承压座置于锚孔内、并通过承压座固定于土体外表面；锚头中部锁锚孔内设有与电源相连的熔断器。施工时，利用钻机在土体内钻出T形锚孔，将锚头插入锚孔底部，锚索束与承压座相连；锚孔内注入水泥浆并养护至抗压强度达到规定值后，对所有锚索束进行分级张拉且无位移；通过承压座上的压力传感器来监测锚索束伸长量变化；施工完熔断器通电融化使锚头脱落，回收锚索束。本发明具有施工简便、回收便捷、承载力大、成本低、对地下污染小的优点。
