Background technique
Currently, being used in the anchor pole of soil-slope supporting, pattern foundation pit supporting structure and substrate anti-floating, structure is generally three kinds, one kind
It is that anchoring section is threaded, there are also one is anchoring section band positioning plate, there are also not only threaded but also with positioning plate one is anchoring section band；
It generally bores a hole when use in soil layer in advance, then anchor pole is placed in hole, the finally slip casting in hole, until slurry solidifies
After reaching certain intensity, anchor pole and cured slurry start to play a role, and prevent the periphery soil body from generating and glide or protuberance, this kind of
Anchor bolt construction process is more, and needs to reach the effect of some strength competence exertion until slurries, so the construction time is also grown.
Through retrieving, Chinese patent application publication No. CN107120132A discloses a kind of anchor pole, solves existing anchor pole peace
Full the problem of hidden danger is larger, working efficiency is low, higher cost, including first body of rod, second body of rod, chain connected nut, unloading nut,
One end of first body of rod, second body of rod is equipped with the external screw thread to match with chain connected nut, first body of rod, second
The body of rod is linked as one by chain connected nut；The other end of second body of rod is provided with and lock washer, locking nut, unloading nut pair
The external screw thread answered successively loads onto lock washer, unloading nut and locking nut at the end.
When in use, external bond stress makes in incremental state the internal pressure of anchor pole to existing anchor pole, thus
The bearing capacity that will cause anchor pole anchor pole itself is excessive, eventually leads to anchor pole fracture, therefore restore in great security risk.
Utility model content
The purpose of this utility model is to provide dispersed pressure anchor structure, by the anchoring section and free segment of setting,
So that cohesive force suffered by anchor pole is in a uniform distribution, and non-bending steel cable corresponding to the different location on anchor pole
The advantages of quantity is different, and non-bending steel cable can increase the potential bearing capacity inside anchor pole, solve existing anchor pole when in use,
Its external bond stress makes in state is incremented by, to will cause the bearing capacity mistake of anchor pole anchor pole itself internal pressure of anchor pole
Greatly, the problem of eventually leading to anchor pole fracture.
According to the dispersed pressure anchor structure of the utility model embodiment, including anchoring section and free segment, the anchoring
Section is fixedly connected with free segment, and the free segment includes the end to end anchorage of multiple units, one end of the anchorage on top
Equipped with protective cover, the bottom side edge of the protective cover is equipped with along base in hollow structure, the anchorage outer wall of lower part is equipped with
Drilling, the anchoring section includes Grouting Pipe, and the side of the Grouting Pipe is evenly distributed multiple supporting bodies, the carrying of lower part
It is fixed with multiple non-bending steel cables in vivo, described non-bending steel cable one end sequentially passes through remaining supporting body and end and anchorage
Bottom end be connected.
Further, multiple isolation rings are uniformly placed on the inner wall of the anchoring section and free segment, the isolation ring
Middle part and four sides are equipped with multiple impenetrating mouths vertically.
Further, the internal diameter of the impenetrating mouth is greater than the outer diameter of non-bending steel cable.
Further, the drilling is connected with the inside of Grouting Pipe.
Further, it is filled with cement slurry inside the Grouting Pipe, the cement slurry passes through the port on supporting body
Flow into slip casting bottom of the tube.
Further, the internal diameter of the port is much larger than the outer diameter of non-bending steel cable.
Further, the non-bending steel cable between the adjacent supporting body successively increases from bottom to top.
Further, the anchoring section isolation ring spacing adjacent with inside free segment is 2-3m.
Further, the supporting body is the axial direction arrangement that fixation hole is opened up along bottom to the anchor pole of drilling.
The utility model has the beneficial effect that compared with prior art
1, by the anchoring section of setting and free segment, so that cohesive force suffered by anchor pole is in a uniform distribution, and
Non-bending steel cable quantity corresponding to different location on anchor pole is different, and non-bending steel cable can increase the carrying inside anchor pole
Potentiality, and be connected to a fixed with supporting body, improve the utilization efficiency of anchor rod anchored segment length；
2, multiple unit bolts are just needed when making high-bearing capacity anchor pole, when use prestress wire is as anchor pole bar
When body, each unit bolt needs symmetrical two non-bending steel cables, and the non-bending steel cable quantity in fixing end is more, and
Since the diameter inside free segment is limited, this requires want strict control free segment and soap-free emulsion polymeization steel to twist when anchor pole makes
The gap of line, thus increase anchor rod anchored section of endurance, the bearing capacity of free segment.
