Abstract
The utility model relates to a mining survival active supporting net, which comprises a supporting net, a riveting rod, an anchor net and a net beam. A left steel wire and a right steel wire form parallelogrammic meshes, salient points are formed on the surfaces of the left steel wire and the right steel wire, a rim is arranged on the periphery of the net, and the left steel wire and the right steel wire are fastened for connection at each node, so as to form a steady structure, facilitate connection between the supporting net and the riveting rod, the anchor net as well as the net beam, and improve strength. With the difference of the geological structures, the supporting method is improved from passive supporting to active supporting.
Description
Technical field:
The utility model relates to a kind of mining protecting wire net, is used for the supporting of mine underworkings, and the supporting for Yan Ding and two gussets prolong refers to active protecting wire net of a kind of mining existence especially.
Background technology:
A protecting wire net of down-hole use at present, what have is woven plastic wire or manual mesh grid.Loose, the easy net that hangs down of Chang Rongyi when top board, two is helped supporting, difficulty is bigger in process of deployment.What have is that horizontal bar is vertical mutually with perpendicular muscle for anchor sprays wire lath basically, and the node place is all welding, has the unsteady defective of structure, and in the middle of the use, metal Netease is phenomenons such as bending, projection in the lane, are unfavorable for the reinforcing and the maintenance in tunnel.Simultaneously can not be along with the difference of geologic structure, supporting method can not improve thereupon.
Summary of the invention:
The purpose of this utility model is to have overcome the deficiencies in the prior art, designs a kind of Stability Analysis of Structures, not yielding, supporting method can improve to some extent along with the geologic structure difference.
The utility model is by a protecting wire net 1, rivet rod 2, anchor net 3, net beam 4 constitutes, constitute the parallelogram mesh by left iron wire 5 and right iron wire 6, on the surface of left side iron wire 5 and right iron wire 6 raised points 7 is arranged, left side iron wire 5 is connected in each node place discount with right iron wire 6, the outer frame 8 that is with of net, prop up protecting wire net 1 usefulness rivet rod 2, anchor net 3, net beam 4 is fixing, the rivet rod tail tightens reinforcing with big mat and nut, rivet rod 2 can use direct paddle type mill according to different intersection of geologic structure, the dilating screw formula, major thread is rotatable, rivet rod 2 main supporting rock stratum crackles, the coal seam crackle, easy slump place of broken foam constitutes robust structure.
The utility model is owing to changed the deficiencies in the prior art, be connected with right iron wire 6 cross arrangement discounts by left iron wire 5, make a protecting wire net 1 under the identical situation of mesh area, intensity improves, dissolve the passive protecting of timber, pole, strip, big girder steel etc., being connected of the also convenient protecting wire net 1 of parallelogram mesh and rivet rod 2, anchor net 3, net beam 4, along with the difference of geologic structure, supporting method also improves to some extent.Become active support by passive protecting.
The beneficial effects of the utility model:
Protection personnel in the pit and equipment alleviate working strength of workers, and easy to use, node place need not weld, and are convenient to transportation; can reuse riveting, save cost, without timber; resource conservation, do not form methane gas and pernicious gas become active support by passive protecting.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial schematic diagram that the utility model is analysed and observe the node place.
Fig. 3 is that the overall structure big gun of the utility model is adopted schematic diagram.
Fig. 4 is the overall structure hydromining schematic diagram of the utility model.
Fig. 5 is that schematic diagram is adopted in the overall structure composition of the utility model.
The specific embodiment:
1-is shown in Figure 5 as accompanying drawing, the utility model is by a protecting wire net 1, rivet rod 2, anchor net 3, net beam 4 constitutes, left side iron wire 5 and right iron wire 6 can adopt the common guiding principle line of 6～10 millimeters of diameters to make, left side iron wire 5 and right iron wire 6 constitute the parallelogram mesh, the length of side of parallelogram is generally 120～240 millimeters, the size of net sheet generally is 130 * 650 meters, on the surface of left side iron wire 5 and right iron wire 6 raised points 7 is arranged, the outer frame 8 that is with of net, each node place discount of frame 8 and left iron wire 5 and right iron wire 6 is connected, frame 8 can adopt the common thick guiding principle line of 6～10 millimeters of diameters to make, and left iron wire 5 and right iron wire 6 difference discounts are on two limits of frame 8.In the practical operation, protecting wire net 1 usefulness rivet rod 2, net anchor 3 are fixed, the rivet rod tail tightens reinforcing with big mat and nut, rivet rod 2 can use direct paddle type mill, dilating screw formula, major thread rotatable according to different intersection of geologic structure, rivet rod 2 can reuse, and fixing with net beam 4 to top board, net beam 4 can adopt wide 18～20 millimeters general steel plate and iron plate, thickness is 0.3～1.0 millimeter, and net beam 4 can suitable can be installed sidewards according to the geologic structure difference.
