Embodiment Construction

[0025] Such as figure 1 As shown, the technical problem to be solved by the present invention is achieved through the following technical solutions. The present invention discloses a segmented clamping anchor cable, including unbonded steel strand 11, bearing plate 2, plastic separator 3, Anchor section slurry 4, winding carrier 5, free section slurry 6, slope restraint member 7 and borehole 8, said borehole 8 is separated into inner anchor section slurry 4 by said plastic separator 3 and the free segment slurry 6 of the outer section, the slope restraining member 7 is arranged on the outer slope, and one end of the unbonded steel strand 1 is connected with the slope restraining member 7 to form an externally tensioned end 11, without The other end of the bonded steel strand 1 passes through the bearing plate 2 and passes through the bearing plate 2 again in the opposite direction through the winding carrier 5 to form an inner tension end 12, and the outer tension end 11 can d...

Abstract

The invention relates to the field of geotechnical engineering anchoring, in particular to a segmented clamping type anchor cable and a mounting method thereof. The anchor cable comprises an unbondedsteel strand, a bearing plate, a plastic isolation body, an anchoring section slurry body, a winding bearing body, a free section slurry body, a slope surface restraining component and a drilled hole,the drilled hole is divided into an inner-section anchoring section slurry body and an outer-section free-section slurry body through the plastic isolation body, the slope surface restraining component is arranged on an outer slope surface, one end of the unbonded steel strand is connected with the slope surface restraining component to form an outer tensioning end, and the other end of the unbonded steel strand penetrates through the bearing plate, reverses through the winding bearing body and then passes through the bearing plate reversely again to form an inner tensioning end. According tothe anchor cable and the mounting method, the free-section slurry body and the anchoring-section slurry body are arranged in a separated mode, so that the depth of the slope anchoring area is greatlyincreased, and moreover, each section of slurry body has good stress conditions so as to achieve a good reinforcing effect.

Description

technical field [0001] The invention relates to the field of geotechnical engineering anchoring, in particular to a section clamping anchor cable and an installation method thereof. Background technique [0002] Prestressed anchor cables are widely used in the field of geotechnical engineering, especially landslide control and slope reinforcement. One end of it is fixed in a stable rock and soil mass, which is called the anchor section; the other end can be freely expanded and contracted, called the free section, which is locked on the restraining member. By stretching the anchor bar (steel strand or steel bar), the tension is transmitted to the restraining member, and the restraining member exerts pressure on the rock and soil mass, forming a compressive stress field in the rock and soil mass within a certain depth range, thereby improving the rock and soil mass. stability. [0003] However, according to the research, the formation depth of the compressive stress field in...
