Abstract
The utility model discloses a shearing resistant slip casting anchor rod. An auxiliary rod body and a main rod body are connected to form into the shearing resistant slip casting anchor rod; the auxiliary rod body is a section high-strength seamless steel pipe; the end of the high-strength seamless steel pipe, which is arranged outside a hole, is machined with threads and provided with tray and a nut; the main rod body is a flexible pipe which is provided with a plurality of slip casting holes with the interval of certain distance; steel strand supports are arranged at the slip casting holes; steel strands wind on the flexible pipe to form into rope shapes; the steel strands at the slip casting holes are opened through the steel strand supports to form into slip casting gaps; when the auxiliary rod body and the main rod body are connected, the flexible pipe is inserted into the high-strength seamless steel pipe to be communicated, the steel strands are connected to the end portion of the high-strength seamless steel pipe, and accordingly the auxiliary rod body and the main rod body are connected into a whole. The shearing resistant slip casting anchor rod has the advantages of being flexible, high in intensity and strong in shear fracture resistant and improving the support effect of weak surrounding rock engineer due to the facts that anchoring of the anchor rod in integral length is achieved through gradual slip casting and surrounding rock is reinforced due to diffusion of thick liquid.
Description
Technical field
The utility model anchor pole relates to engineering support anchor pole, relates in particular to grouted anchor bar.
Background technology
Anchor pole can be used for shaft and drift supporting in mine engineering and other underground constructions, dam reinforcement, landslide control, tunnel reinforcement, the fields such as Soft Soil Foundation Pit reinforcing.Large at some weak surrounding rocks and distortion, generally use grouted anchor bar in destroying serious well lane engineering.The structure of grouted anchor bar is to be mainly provided with nut and pallet at the outer end of hole of seamless steel pipe, and seamless steel pipe is provided with injected hole.When use, grouted anchor bar is inserted after boring, with grouting pump by steel pipe to slip casting in the crack of boring and boring, carry out reinforce adjoining rock with the diffusion of slurries, slurries solidify the globality of rear raising country rock, and play full length fastening anchorage effect.
Because weak surrounding rock distortion is large, features as poor geologic condition, anchor pole also bears radial shear power except bearing axial tension.Because anchor rod body is stiffening member, though sometimes anchor rod body not yet reaches the disrumpent feelings limit, easily there is shear failure, cause supporting and protection structure unstability.In addition, the length of grouted anchor bar is far longer than the width in tunnel sometimes, and steel tube body is not easy bending, cannot in gun drilling, install,
Summary of the invention
Easily be sheared the problem of destruction in order to solve current grouted anchor bar, design a kind of shearing resistance grouted anchor bar.
A kind of shearing resistance grouted anchor bar, it is connected to form by the secondary body of rod and main rod body; The described secondary body of rod is one section of high-strength seamless steel pipe that 1-2 rice is long; The outer end of hole of high-strength seamless steel pipe is processed with screw thread, and is provided with pallet and nut; Described main rod body is made up of thin flexible pipe and the some strands of steel strand of the secondary body of rod diameter of ratio, its structure is, on flexible pipe, be provided with some injected holes at interval of certain distance, injected hole place is provided with steel strand support, on flexible pipe, being wound with steel strand becomes cord-like, and the steel strand at injected hole place are strutted and form slip casting gap by steel strand support; When the secondary body of rod is connected with main rod body, flexible pipe injects in high-strength seamless steel pipe and mutual UNICOM, and steel strand are connected to the end of high-strength seamless steel pipe, thereby the secondary body of rod and main rod body are linked into an integrated entity.
Good effect of the present utility model is:
1, the body of rod of shearing resistance grouted anchor bar is multiply steel hank knotting two parts of high-strength seamless steel pipe and twisting, and main rod body is flexible structure, and elongation rate is large, and shear strength is high, is difficult for disrumpent feelingsly, and exploitativeness is good.
2, main rod body inside is established steel bracket and is formed hollow structure, inside establishes flexible grout pipe, and Grouting Pipe is connected with seamless steel pipe, guarantees that slurries are full of boring.
3, outer anchor head is that screw-thread steel is connected with hollow seamless steel pipe, is convenient to field conduct and installs.
4, the secondary body of rod is hollow seamless steel pipe, is the rigidity body of rod of anchor pole, and the intensity of the body of rod is high, and can be used for slip casting, outer anchor head is installed convenient.
In a word, the installation of this anchor pole is simple, has flexibility, high, the anti-shearing destruction of intensity is strong, has realized the full length fastening of anchor pole by slip casting gradually simultaneously, carrys out reinforce adjoining rock with the diffusion of slurries, thereby improves the supporting effect of weak surrounding rock engineering.

The specific embodiment
Shearing resistance grouted anchor bar as depicted in figs. 1 and 2, it is connected to form by the secondary body of rod and main rod body; The described secondary body of rod is one section of high-strength seamless steel pipe 3 that 1-2 rice is long; The outer end of hole of high-strength seamless steel pipe 3 is processed with screw thread, and is provided with pallet 1 and nut 2; Described main rod body is made up of thin flexible pipe 5 and the some strands of steel strand 4 of the secondary body of rod diameter of ratio, its structure is, on flexible pipe 5, be provided with some injected holes 6 at interval of certain distance, injected hole 6 places are provided with steel strand support 7, steel strand 4 are wrapped on flexible pipe 5 becomes cord-like, and the steel strand 4 at injected hole 6 places are strutted and form slip casting gap by steel strand support 7; When the secondary body of rod is connected with main rod body, flexible pipe 5 injects in high-strength seamless steel pipe 3 and mutual UNICOM, and steel strand 4 are connected to the end of high-strength seamless steel pipe 3, thereby the secondary body of rod and main rod body are linked into an integrated entity.
