Abstract

The utility model relates to a cavity slip casting internal stay diffusion formula stock device, this anchor rod device be including being equipped with the stock inner tube of rotary -table (the rigidity of rotary -table), and interior pipe box wherein leaves the injected hole on the pipe wall in the stock in being equipped with the stock outer tube of the steel bloom body of taking the line tooth, and the slip casting mouth is also left to stock outer tube bottom, takes that to be equipped with the triangular prism steel on the steel bloom body of line tooth stifled with the quadrangular steel. Through to stock inner tube pressurization, cause the steel bloom body of taking the line tooth on the rotary -table extrusion stock outer tube to make the steel bloom body form the squeezing action to the drilling inner wall, increase the whole anchoring strength of stock and rock mass. The utility model discloses the manufacturing principle is clear, the simple structure, and the anchor effect is strong.

Description

A kind of hollow slip casting inner support diffusion formula anchor pole

Technical field

The utility model relates to a kind of engineering support instrument, is applied to Geotechnical Engineering field.It is hollow slip casting inner support diffusion formula anchor pole.

Background technology

At present, in geotechnical engineering field, the distortion of rock mass is collapsed and all can be affected the development of whole programming with unstability, and the stabilization works for rock mass is particularly important, and bolt support obviously becomes a kind of supporting tool preferably.

In existing mooring rod technique, empty slip casting and inner support diffusion is concentrated to develop relative imperfection in the anchor pole of one, although other hollow grouting anchors can reach fixing fragmented rock body, realize the objects such as slip casting, but at some, Surrounding Rock Strength is required, in the middle of higher engineering, cannot reach its requirement of strength.

Summary of the invention

In view of other hollow grouting anchors cannot realize slip casting and the effect with inner support diffusion simultaneously, do not reach best supporting effect.The utility model provides a kind of bolt support instrument-hollow slip casting inner support diffusion formula anchor pole, possesses supporting effect strong, the advantages such as convenient construction.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of hollow slip casting inner support diffusion formula anchor pole, comprise the anchor pole outer tube that band line tooth bloom body is housed, the interior pipe that Rotary-table is housed, with on the bloom body of line tooth, triangular prism steel pin and quadrangular steel pin are housed, steel pin and bloom body adopt and are welded to connect.

As a kind of preferred version of the present utility model, the triangle steel pin of this hollow slip casting inner support diffusion formula anchor pole and corner steel pin are mainly used in the position of fixing bloom body and anchor pole overcoat, the length that control corner steel pin and anchor pole overcoat stretch out.

As another kind of preferred version of the present utility model, the Rotary-table of this hollow slip casting inner support diffusion formula anchor pole is connected with pipe in threaded anchor pole, and Rotary-table in anchor pole on pipe position fix, Rotary-table moves together with managing in anchor pole as a whole.Rotary-table is mainly used in, by the bloom body of extruding with line tooth, making bloom body extrude drill hole inner wall under pressure, thus increasing the intensity of boring.

As another preferred version of the present utility model, injected hole is left on bottom this hollow slip casting inner support diffusion formula anchor pole inner pipe wall and pipe, and inner tube diameter is identical with the grouting port bore of the bottom of outer tube, be convenient to realize coherent formula slip casting when interior pipe arrives outer sleeve bottom.

The beneficial effects of the utility model are: the utility model adopts the barrel forms of the interior pipe be with the outer tube of line tooth bloom body and Rotary-table is housed, by internal pipe Shi Hanzhang, make the generation squeezing action of the bloom body of Rotary-table in anchor pole on pipe and anchor pole outer tube, thus bloom body is extruded anchor pole outer tube, extruding force is formed to drill hole inner wall, achieves the inner support diffusion effect of anchor pole to rock mass, enhance the intensity of rock mass, this anchor pole reliability is high, simple to operate, strengthens effective.

Detailed description of the invention

The utility model is further described with detailed description of the invention by reference to the accompanying drawings.

As shown in Figure 1, hollow slip casting inner support diffusion formula anchor pole, comprise pipe (6) in screwed anchor pole, in anchor pole, pipe (6) is equipped with two Rotary-tables (2) fixing position, and is threaded connection.

The bloom body (7) of four identical band line teeth anchor pole outer tube (8) each aspect is all equipped with, upper and lower aspect totally eight.The bloom body (7) of each band line tooth is equipped with a triangular prism steel stifled (3) and three quadrangular steel stifled (4), as shown in Figure 1, the Main Function of triangular prism steel stifled (3) and quadrangular steel stifled (4) is to make the bloom body (7) of band line tooth be fixed on anchor pole outer tube (8) to its particular location.

In order to realize this preferred embodiment, time static, Rotary-table (2) in anchor pole on pipe (6) just just contacts with the bloom body (7) with line tooth in this aspect, and contact surface is smooth, the inclined-plane angle of the bloom body with line tooth is less than 45 degree, and the bloom body (7) with line tooth can be moved to anchor pole outer tube (8) outside.

When managing (6) by External Force Acting in anchor pole, along with the increase Rotary-table (2) of pressure moves down, extruded by the bloom body (7) of its arc surface and external belt line tooth, make to be with the bloom body of line tooth to move to the outside of anchor pole outer tube (8), when moving to certain distance, when being namely with the triangular prism steel on bloom body (7) top of line tooth stifled (3) just in time to contact with the tube wall of anchor pole outer tube (8) with the quadrangular steel stifled (4) of bottom, keep constant voltage, stop grouting plug (11) and backing plate (10) are installed, tighten with special nut (9), connect slurry filling machine and start slip casting by quick slip casting interface, slip casting terminates stifled slurry plug (12) of rear use and clogs.
