Abstract
A sectional anchor cable design method divides an anchor cable (2) at a free section into a plurality of sectional anchor cables with equal length, and each two sections of anchor cables are connected through a clip type anchorage device (7) and a horn lock catch (8); each anchor cable segment is connected through a clip type anchor, and every two adjacent clip type anchors are connected through three horn lock catches which form an angle of 120 degrees with each other to form an anchor cable bundle. The sectional anchor cable consists of an end anchor section, a free section and an anchoring section. After the sectional anchor cable is used as a temporary supporting structure to lose the function, when foundation pit excavation is carried out on the periphery of the temporary supporting structure, the sectional anchor cable can be separated by using machinery to unlock or break the ox horn lock handle, and then the separated sectional anchor cable far away from the anchoring end side is pulled out by using machinery, so that construction excavation is continuously carried out while part of the anchor cable structure is recovered; the method and the device have the advantages that the obstruction of the existing anchor cable to the excavation of the foundation pit at the periphery of the later stage is reduced under the condition that the anchor cable is not recycled, and the cost of the foundation pit construction at the later stage is reduced.
