Abstract
The utility model relates to an anchor rod subsection control retaining and protecting device for a large-deformation roadway. The anchor rod subsection control retaining and protecting device for the large-deformation roadway comprises an anchor rod body, a cone-shaped bolt I, a supporting disk, a bended anchor rod and a cone-shaped bolt II. The portion, located in a pressure and displacement yielding section rod hole, of the anchor rod body is the bended anchor rod. The inner end of the bended anchor rod is connected with the cone-shaped bolt II. The outer end of the bended anchor rod is connected with the supporting disk and the cone-shaped bolt in sequence. The supporting disk and the cone-shaped bolt I are arranged outside the pressure and displacement yielding section rod hole. The anchor rod subsection control retaining and protecting device for the large-deformation roadway reduces the pressure borne by an anchor rod and an anchor cable arranged in the coal and rock shallow portion of the lower side portion in the large-deformation roadway, prevents the anchor rod and the anchor cable from being broken, controls the stability of deep coal and rock, improves the overall supporting capacity of the side portion coal and rock, achieves enhancement of anchor rod retaining and protecting of coal of the deep portion, and guarantees the continuity of the retaining and protecting pressure of the roadway.
Description
Technical field
The utility model relates to the mine laneway safety device, especially a kind of Rock Bolts in Roadways with Large Deformation segmentation control suspension device.
Background technology
When the tunnel deforms, section of side coal and rock is at first broken, because the horizontal stress at section of side edge is less than normal than the deep, deformation displacement is bigger than normal than the deep, vertical support power a little less than, if roof and floor is still very large to the pressure of section of side, the coal and rock superficial part stress generation large deformation of section of side produces larger destruction to anchor shaft anchor cable, even anchor shaft anchor cable is broken, thereby affect the safety in tunnel, common support pattern can't address the above problem.
The utility model content
The pressure that bears for the anchor shaft anchor cable that alleviates section of side coal and rock superficial part under the large deformation of roadway, prevent that anchor shaft anchor cable from being broken, the integrated support ability of stable and section of the raising side coal and rock of control deep coal and rock, the utility model proposes a kind of Rock Bolts in Roadways with Large Deformation segmentation control suspension device, realization is not strengthened bolt support to the deep coal body not being allowed press, and guarantees the continuity of roadway support pressure.
The technical scheme that its technical problem that solves the utility model adopts is: this Rock Bolts in Roadways with Large Deformation segmentation control suspension device comprises anchor pole main body, taper bolt I, pallet, crooked anchor pole and taper bolt II; Described anchor pole main body is positioned to allow press and allows the part in displaced segments bar hole be crooked anchor pole; The inner end of described crooked anchor pole is connected with taper bolt II, the outer end of crooked anchor pole be linked in sequence pallet and taper bolt I; Pallet and taper bolt I are located to press and allow the outside in displaced segments bar hole.
Described allow press allow displaced segments bar hole be connected superficial part with anchoring section bar hole to connect to the deep order and connect, allow press allow the aperture in displaced segments bar hole greater than the aperture in anchoring section bar hole.
The minimum diameter of described taper bolt II is greater than the diameter in anchoring section bar hole.
The diameter of described pallet allows the diameter in displaced segments bar hole greater than allowing press.
The beneficial effects of the utility model are: this Rock Bolts in Roadways with Large Deformation segmentation control suspension device, alleviated the pressure that the anchor shaft anchor cable of section of side coal and rock superficial part bears under the large deformation of roadway, prevent that anchor shaft anchor cable from being broken, the integrated support ability of stable and section of the raising side coal and rock of control deep coal and rock, realization is not strengthened bolt support to the deep coal body not being allowed press, and guarantees the continuity of roadway support pressure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the structural representation of this Rock Bolts in Roadways with Large Deformation segmentation control suspension device.
Among the figure, 1. tunnel, 2. anchor pole main body, 3. taper bolt I, 4. pallet, 5. crooked anchor pole 6. allows press allow displaced segments bar hole, 7. taper bolt II, 8. anchoring section bar hole.
The specific embodiment
In accompanying drawing 1, this Rock Bolts in Roadways with Large Deformation segmentation control suspension device comprises anchor pole main body 2, taper bolt I3, pallet 4, crooked anchor pole 5 and taper bolt II7; Described anchor pole main body 2 is positioned to allow press and allows the part in displaced segments bar hole 6 be crooked anchor pole 5; The inner end of described crooked anchor pole 5 is connected with taper bolt II7, the outer end of crooked anchor pole 5 be linked in sequence pallet 4 and taper bolt I3; Pallet 4 and taper bolt I3 are located to press and allow the outside in displaced segments bar hole 6.
Described allow press to allow displaced segments bar hole 6 be connected with anchoring section bar hole and to be connected to the deep order by superficial part connect, allow press allow the aperture in displaced segments bar hole 6 greater than the aperture in anchoring section bar hole 8.
The minimum diameter of described taper bolt II7 is greater than the diameter in anchoring section bar hole 8.
The diameter of described pallet 4 allows the diameter in displaced segments bar hole 6 greater than allowing press.
Described crooked anchor pole 5 is uniform undaform, make it possess larger elasticity, rock mass stress is to the destruction of anchor pole when reducing large deformation of roadway, simultaneously pallet 4, taper bolt I3 and taper bolt II7 can make and become bent anchor pole 5 and be fixed on to allow press and allow in the displaced segments bar hole 6, prevent its left and right sides play, the deep coal body is not allowed press strengthen bolt support.
