Abstract
The utility model relates to a control device for a bottom plate of a roadway with an erecting shed support. A beam is arranged on the bottom plate on the lower portion of the erecting shed support and abutted to the space between shed legs, the beam and the bottom plate are provided with drilling holes downwardly, a tray and a nut are mounted on an exposed section of the upper end of each anchor rod sequentially, the anchor rods are mounted in the bottom plate through the holes of the beam, the lower end of each anchor rod is connected with a resin explosive cartridge in an anchoring mode, and anchoring areas of the anchor rods in the same line are combined by the beam so as to form an integral closed support structure with the erecting shed support. By the aid of the control device for the bottom plate of the roadway with the erecting shed support, bottom plate control measures are integrally connected with the erecting shed support, a stress state of bottom plate surrounding rocks is improved, a plane stress state is changed to a three-dimensional stress state, and a floor heave is effectively controlled.
Description
Technical field
The utility model relates to a kind of device of controlling the tunnel pucking, especially a kind of shed shoring roadway floor control device.
Background technology
Shed shoring is a kind of support form that generally adopts in the coal mine roadway, shed shoring can effectively support back and two and help, and control is crushed and two helped to shift near, but base plate often is in the non-support state, along with the transfer and the adjustment of roadway surrounding rock stress, be easy to take place strong pucking.
At present, the major technique means of control tunnel pucking have the full section supporting of base plate anchor shaft anchor cable, floor grouting, concrete arch and arc plate.Complex procedures when adopting the full section supporting of concrete arch and arc plate, engineering quantity are big, and The field is less.When construction baseboard anchor cable or floor grouting, the base plate control measure are separated with helping the top supporting measure, and are also not good enough to the base plate regulation effect.
The utility model content
In order to overcome the problem that pucking takes place easily in existing supporting tunnel, the utility model provides a kind of shed shoring roadway floor control device, this control device can form the supporting of base plate control measure unit-frame canopy unified whole, improves the bottom slab stress state, effectively controls pucking.
The technical scheme that its technical problem that solves the utility model adopts is: on the base plate of shed shoring bottom, withstand between the canopy leg, be provided with crossbeam, crossbeam and base plate have boring downwards, the upper end revealed section of anchor pole is equipped with pallet, nut successively, and anchor pole is installed in the base plate by the hole of crossbeam, the lower end of anchor pole and resin explosive roll anchor connection, to combine with the anchorage zone of row's anchor pole by crossbeam, form whole sealing supporting and protection structure with shed shoring.
Crossbeam is channel-section steel, i iron or steel band, and the length of crossbeam equals the distance between the shed shoring canopy leg.Opening on the crossbeam is two to five, and pitch of holes equates.Anchor pole also can replace with anchor cable, also can replace with rigging to nut simultaneously.
During use, the crossbeam two ends of this device are against on the canopy leg of shed shoring, can be combined in one with adjacent anchor pole of row or anchor cable on the roadway floor, form supporting and protection structure.
The beneficial effects of the utility model are, this shed shoring roadway floor control device makes the anchorage zone of anchor pole or anchor cable link to each other, the supporting of base plate control measure unit-frame canopy is connected into an integral body, improve the floor rocks stress, become triaxial stress state by plane stress state, effectively control pucking.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a cross-section structure principle schematic of the present utility model.
Among the figure, 1. nut, 2. pallet, 3. crossbeam, 4. canopy leg, 5. base plate, 6. anchor pole, 7. boring, 8. resin explosive roll.
The specific embodiment
In Fig. 1, on the base plate 5 of shed shoring bottom, withstand between the canopy leg 4, be provided with crossbeam 3, crossbeam 3 and base plate 5 have boring 7 downwards, and the upper end revealed section of anchor pole 6 is equipped with pallet 2, nut 1 successively, anchor pole 6 is installed in the base plate 5 by the hole of crossbeam 3, the lower end of anchor pole 6 and resin explosive roll 8 anchor connections will be combined with the anchorage zone of row's anchor pole 6 by crossbeam 3, form whole sealing supporting and protection structure with shed shoring.
In Fig. 1, described crossbeam 3 is channel-section steel, i iron or steel band, and the length of crossbeam 3 equals the distance between the shed shoring canopy leg 4.
In Fig. 1, the opening on the described crossbeam 3 is two to five, and pitch of holes equates.
In Fig. 1, described anchor pole 6 also can replace with anchor cable, simultaneously nut 1 is replaced with rigging.
During use, crossbeam 3 two ends of this device are against on the canopy leg 4 of shed shoring, can be combined in one with adjacent anchor pole 6 of row or anchor cable on the roadway floor 5, form supporting and protection structure.
Claims (3)
