Specific implementation mode
Specific embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model provides one kind stopping sizing device suitable for rock side slope supporting anchorage cable slip casting, it includes
Anchor cable hole 1 and the anchor cable 2 in the anchor cable hole 1.The anchor cable 2 includes several parallel steel strand wires 3, and 3 inner end of steel strand wires is equal
It is connected to Inner bolt head 4.3 middle part of steel strand wires is arranged with soft rubber capsule 5, which is respectively equipped with upper grip 6 under
Collet 7 seals the soft rubber capsule 5.The steel strand wires 3 are internally provided with and the first Grouting Pipe 8 of 1 external connection of the anchor cable hole and
The grout outlet of two Grouting Pipes 9, first Grouting Pipe 8 is located between the Inner bolt head 4 and 1 inner end of anchor cable hole, second Grouting Pipe 9
Grout outlet be located in the soft rubber capsule 5.
4 inner end of Inner bolt head is equipped with the guiding cap 10 of taper, and the grout outlet of first Grouting Pipe 8 is located at outside the guiding cap 10
Portion.The part that the steel strand wires 3 are located at outside the anchor cable hole 1 is arranged with outer anchor head 11, which is internally provided with and the anchor cable
The injected hole 12 that 1 inside of hole is connected to.
Steel strand wires 3 at the upper grip 6 and lower collet 7 are wound with flexible filler, such as can be twisted steel with waste and old towel
Line is wound up, and round two Grouting Pipe close-packed arrays, is then closely bound at both ends using strap.The soft rubber capsule 5
Both ends are located in the middle part of the flexible filler, and are fixedly clamped sealing by the upper grip 6 and lower collet 7.When installation, in upper and lower collet
