Description

Foundation pit side slope supporting prestressed anchorage cable structure Technical Field The utility model relates to the technical field of anchor cables, in particular to a foundation pit side slope support pre-stress anchor cable structure. Background In the process of foundation ditch excavation and foundation ditch construction, all need consolidate the side slope of foundation ditch and handle, avoid appearing the side slope and empty or incident such as landslide, influence the going on of construction, common processing method is for setting up foundation ditch side slope support, in the setting of foundation ditch side slope support, can use the prestressed anchorage cable structure, can be better fix the side slope support, provide tensile properties, guarantee the safety of support. The utility model discloses a green construction is with prestressing force anchor rope stop device for CN120159192A, including the ground tackle, a plurality of jack holes of wearing have been seted up on the ground tackle, a plurality of jack holes of wearing are inside all to be provided with the clamping piece of inner chamber shape assorted, a pair of mutually symmetrical mounting groove has been seted up on the inner wall of jack hole of wearing, sliding connection has the extrusion piece in the mounting groove, and the mounting groove is inside to be provided with the spring, through set up a pair of extrusion piece in the inside of interlude hole, the less one end of clamping piece bore is all the time with anchor rope surface butt in forcing the anchor rope tensile process, thereby in the moment that the anchor rope kick-backs, can drive the clamping piece immediately to move in the jack hole of wearing through frictional force, make the clamping piece get into the inside of jack hole completely with fastest speed and produce deformation, and then make the anchor rope just be fixed immediately under the extrusion effect of clamping piece after a short distance of kick-backing, effectively reduced prestressing force loss, construction quality has been improved.
