Abstract

The utility model discloses a kind of strong dynamic load anti-impact supporting new structures in tunnel, it is made of country rock, anchor cable, broken rock, anchor net, fender flitch, top steelframe, supporting steel frame, bottom steelframe, energy-absorbing material cushion block, connecting plate, fractured rock bottom plate, cement pouring layer, the anchor cable sequentially passes through anchor net, broken rock, country rock, and the broken rock is arranged between anchor net and country rock;The fender flitch is arranged between anchor net and top steelframe, supporting steel frame, bottom steelframe, and the top steelframe, supporting steel frame, bottom steelframe are linked together by connecting plate;The cement pouring layer is arranged in tunnel whole surface.The utility model has the following advantages that and good effect:Anchor cable plays the role of tunnel and is connect with country rock;Broken rock has certain buffering energy-absorbing function;Fender flitch plays the role of secondary buffer;Energy-absorbing material cushion block plays the role of secondary energy-absorbing;The surface in tunnel is cement pouring layer, can reduce the effect of ventilation resistance to avoid air leakage in roadway.

Description

A kind of strong dynamic load anti-impact supporting new structure in tunnel
Technical field:
The utility model is related to the strong dynamic load anti-impact supporting new structures in roadway support field more particularly to a kind of tunnel.
Background technology:
Tunnel is the important channels such as mining conveying, personnel's walking, air flowing, and the safe condition maintenance in tunnel is to ensure Mine safety production important leverage.But for the larger rock stratum tunnel of some dynamic pressures, often there is drift section deformation, even The hidden danger caved in.Cross section deformation once occurs for tunnel, very big to Ventilation Effect, is easy to cause mine air disorderly, influence just The air feed of normal working face.If tunnel caves in, it is most likely that cause damages to mine person property.
Utility model content:
Problem to be solved in the utility model is to provide a kind of novel roadway support structure, is suitable for strong dynamic load tunnel Supporting.
Technical solution used by the utility model is:A kind of strong dynamic load anti-impact supporting new structure in tunnel, by country rock, anchor Rope, broken rock, anchor net, fender flitch, top steelframe, supporting steel frame, bottom steelframe, energy-absorbing material cushion block, connecting plate, kata-rocks Stone bottom plate, cement pouring layer are constituted, and the anchor cable sequentially passes through anchor net, broken rock, country rock, and the broken rock is arranged in anchor Between net and country rock;The fender flitch is arranged between anchor net and top steelframe, supporting steel frame, bottom steelframe, the top steelframe, Supporting steel frame, bottom steelframe are linked together by connecting plate, and the top steelframe is arranged on the upside of tunnel, and the bottom steelframe is arranged in lane On the downside of road, the supporting steel frame is located between top steelframe and bottom steelframe;The energy-absorbing material cushion block is arranged in top steelframe, supporting steel Junction between frame, bottom steelframe, the energy-absorbing material cushion block are located inside connecting plate;The fractured rock backplane is the bottom of at On the upside of steelframe;The cement pouring layer is arranged in tunnel whole surface.
A diameter of 1-2cm of the anchor net mesh.
The fender flitch is made of padded coaming, primarily serves the effect of cushion load, that is, reduces shock loading Speed.
The energy-absorbing material cushion block is made of energy-absorbing material, primarily serves the effect for absorbing impact energy, that is, reduces top steel Frame, supporting steel frame, bottom steelframe absorb impact energy.
The upper surface of the fractured rock bottom plate is horizontal plane, primarily serves and is readily transported the effects that walking with personnel.
The utility model has the advantages and positive effects of:(1) anchor cable plays the role of tunnel and is connect with country rock so that Tunnel is integrated with country rock;(2) broken rock can weaken stronger shock loading and be destroyed caused by steelframe, have centainly Buffering energy-absorbing function;(3) fender flitch plays the role of secondary buffer;(4) energy-absorbing material cushion block plays the work of secondary energy-absorbing With;(5) whole surface in tunnel is cement pouring layer, can reduce the effect of ventilation resistance to avoid air leakage in roadway.
Description of the drawings:
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural schematic diagram for pushing up steelframe, supporting steel frame, bottom steelframe and being connected by connecting plate.
Wherein:1- country rocks, 2- anchor cables, 3- broken rocks, 4- anchors net, 5- fenders flitch, the tops 6- steelframe, 7- supporting steels Frame, the bottoms 8- steelframe, 9- energy-absorbing materials cushion block, 10- connecting plates, 11- fractured rocks bottom plate, 12- cement pouring layer.
Specific implementation mode:
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the strong dynamic load anti-impact supporting new structure in a kind of tunnel described in the utility model, works as tunnel When being tunneled into preliminary configuration, anchor net 4 is first laid, then fractured rock is filled between anchor net 4 and country rock 1, form kata-rocks Layer 3.Later, bottom steelframe 8, then the fixed connecting plate 10 on bottom steelframe 8 are first set up, energy-absorbing material cushion block 9 is filled in and is fixedly connected In plate 10, one end of supporting steel frame 7 is then set up in the other end of fixed connecting plate 10;It is fixed in the other end of supporting steel frame 7 Connecting plate 10 fills in energy-absorbing material cushion block 9 in fixed connecting plate 10, then sets up top steel in the other end of fixed connecting plate 10 Frame 6 has eventually formed steelframe overall structure.Then fender flitch 5 is arranged between steelframe overall structure and anchor net 4.The bottom of at 8 upside of steelframe is laid with fractured rock so that the fractured rock upper surface of laying keeps horizontal, ultimately forms fractured rock bottom plate 11.Finally in the outermost whole surface joints cement pouring layer 12 in tunnel.
