Abstract
The utility model discloses a pinniform wedge body stock, include stock tip, pole body, end the thick liquid end, only starch the tip and connected gradually reinforcing bar net, backing plate and nut, its characterized in that: the stock tip includes anchor head, out grouting holes, still includes one section double -deck steel pipe, and the inlayer of double -deck steel pipe is the cavity body of rod, and the external diameter is 20mm, and the skin of double -deck steel pipe is for opening the hollow shell who has a longitudinal joint, and the external diameter is 26mm, has a plurality of pinniform wedges body in the even welding of hollow shell surface, the anchor head is an expansion type anchor head, the pole is as the cavity stock. After drilling construction is accomplished, insert pinniform wedge body stock, carry out slip casting, reach the certain degree when thick liquid intensity, through the nut stock of screwing, the anchor head is driven outside tensile in -process by the nut, and the anchor head tip enlarges, and similar inflation screw, the pinniform wedge body then among the insertible grouting segment, reach the purpose that strengthens adhesion stress between stock and the country rock.
Description
Technical field
The utility model relates to field of civil engineering, particularly a kind of pinniform wedge anchor pole.
Background technology
In civil engineering supporting and field of reinforcement, bolt support is a kind of scheme with economic advantages, now become one of main support form in the geotechnical engineering such as foundation ditch, tunnel and underground construction, current anchor pole is of a great variety, different anchor pole respectively has different advantage and shortcoming, such as in anchor pole and country rock adhesion strength, also has very large room for improvement at present.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides the pinniform wedge anchor pole that a kind of structure is simple, can strengthen anchor pole and country rock adhesion strength.
The technical scheme that the utility model solves the problem is: a kind of pinniform wedge anchor pole, and comprise anchor pole end, shaft, grouting end, grouting end portion is connected with steel mesh reinforcement, backing plate and nut in turn; Anchor pole end comprises anchor head, slurry outlet, also comprises one section of double-layer pipe, and the internal layer of double-layer pipe is hollow lever, external diameter is 20mm, the skin of double-layer pipe is for having the hollow housing of a longitudinal joint, and external diameter is 26mm, has some pinniform wedges at hollow housing external surface uniform welding; Described anchor head is expansion type anchor head; Described shaft is hollow bolt.
In above-mentioned pinniform wedge anchor pole, the described long 720mm in anchor pole end; The quantity of described pinniform wedge is 7 groups, and the quantity often organizing pinniform wedge is 4, and 4 pinniform wedges with group are located in the same horizontal plane and are 90 ° of distributions around hollow housing, and the spacing of two adjacent groups pinniform wedge is 100mm.
In above-mentioned pinniform wedge anchor pole, the longitudinal section of described pinniform wedge is triangular in shape, high 5mm, and length and width are all 3mm.
In above-mentioned pinniform wedge anchor pole, on described hollow housing, the width of longitudinal joint is 2mm.
The beneficial effects of the utility model are: the utility model is provided with double-layer pipe in anchor pole end, the outer layer pipe of double-layer pipe is welded with pinniform wedge, after drilling construction completes, inserts pinniform wedge anchor pole, carry out slip casting, when slurry intensity acquires a certain degree, by nut anchor pole, anchor head is driven in the process stretched out by nut, anchor head end expanding, similar setscrew, pinniform wedge then can embed in injecting cement paste, reaches the object strengthening adhesion stress between anchor pole and country rock.
