In addition, current anchor pole is all scattering device, do not connect each other.In the place that the soil is porous, if wherein A piece anchor pole is broken off losing support action, easily causes country rock to come off and triggers chain reaction, finally results in whole reinforcing work Journey fails, and larger potential safety hazard be present.
Utility model content
For deficiency above-mentioned in the prior art, the utility model, which provides one kind, pressure grouting anchor pole, by pulp passage to Slip casting passage feedstock direction is obliquely installed, and prevents from blocking, and mounting seat is set on backing plate, makes that between anchor pole one can be connected as Body, strengthen consolidation effect.
In order to achieve the above object, the solution of the utility model use is:One kind has pressure grouting anchor pole, including anchor pole Body, anchor head, stop grouting plug, fixing nut, the backing plate of fix bar and arch, the anchor head are located at the head of anchor bar body, fixing nut The afterbody of anchor bar body is located at, backing plate is located between fixing nut and stop grouting plug;The backing plate includes peripheral part and boss portion, periphery Portion is provided with through hole, and fix bar is connected through through hole with backing plate;Slip casting passage is provided with the anchor bar body, on the perisporium of anchor bar body Provided with the pulp passage connected with slip casting passage, the feedstock direction angle of the pulp passage and slip casting passage is 25-45 degree.
Further, including three fix bars, the fix bar are located on three angles of equilateral triangle.
Further, one end of the fix bar is provided with point, and the other end of fix bar is provided with tubular installation Seat.
Further, the perisporium of the fix bar is provided with annular groove, and the cross section of the annular groove is parallelogram.
Further, the perisporium of the mounting seat is provided with the stopper slot of annular.
Further, the cross section of the stopper slot is triangle.
Further, tubular groove is provided with the mounting seat, the perisporium of the groove is provided with screw thread.
The beneficial effects of the utility model are:
(1) pulp passage is obliquely installed to slip casting passage feedstock direction, effectively avoids to cause to apply while blocking Work is difficult, improves efficiency of construction and consolidation effect, reduces construction cost;
(2) fix bar is inserted in country rock by point, and fix bar is provided with mounting seat, can be incited somebody to action using connecting rod or cable wire Mounting seat between anchor pole is connected, and all anchor poles are connected as a single entity, and the anchor pole for preventing from fractureing, which comes off, triggers chain reaction, increases Strong consolidation effect;
(3) fix bar perisporium is provided with the annular groove that cross section is parallelogram, is connected firmly after fix bar insertion country rock, Anchor bar body can be aided in reinforce country rock while increasing mounting seat steadiness;
(4) mounting seat perisporium is provided with the stopper slot that cross section is triangle, connects cable wire or connecting rod is socketed in stopper slot It is interior, anchor pole is prevented because when surrouding rock deformation produces displacement, connects cable wire or connecting rod comes off from mounting seat, equipment dependability is strong;
(5) groove is provided with mounting seat, recess peripheral wall is provided with screw thread, when installing anchor pole, turns in installation equipment insertion groove Dynamic fix bar, makes fix bar stretch into country rock, and during slip casting, slip casting machine is fixedly connected by screw rod with mounting seat, is easy to slip casting to grasp Make.
