Abstract
The utility model relates to a roadway support field, hard and soft combination supporting construction especially, hard and soft combination supporting construction, the arc U shaped steel portion at top of roadway that arranges, straight U shaped steel arranges at tunnel both sides wall, arc U shaped steel passes through U shaped steel clamping cable with U shaped steel directly and is connected, the sleeper has been arranged between the country rock in arc U shaped steel, straight U shaped steel and tunnel, the U type groove opening of arc U shaped steel and straight U shaped steel is towards the sleeper, the bottom plate is laid in the tunnel bottom, cable wire end -to -end connection encloses into the shape of tunnel cross section, distributes below the U type inslot and bottom plate of the U type inslot of arc U shaped steel, straight U shaped steel. The utility model provides a hard and soft combination supporting construction, U shaped steel play rigid support's effect, and when impact load destroyed U shaped steel, its inside cable wire played flexible supprot effect, from the transition period that rigid support strutted to the flexibility, is exactly the cushioning effect of this supporting construction to impact load to play anti effect of dashing.
Description
Technical field
This utility model relates to roadway support field, especially rigid flexible system supporting construction.
Background technology
In China, intensification along with coal mining depth, and supporting continues to increase needed for tunnel, the destruction of bump is aggravated the most again, existing support pattern is the most all the supporting construction under static pressure from surrounding rock, it is difficult to the anti-impact supporting difficult problem that reply is current, because some new support patterns must be proposed again, although up to now, many scholars are had to propose many counter-measures, but these measures, or be that supporting effect is preferable, but cost increases substantially, or do not reach the ideal effect of supporting exactly.
Utility model content
It is the highest that problem to be solved in the utility model is to provide a kind of cost, and the supporting construction that anti-impact is effective.
This utility model be the technical scheme is that
Rigid flexible system supporting construction, is made up of the U-shaped steel of arc, straight U-shaped steel, U-shaped steel card cable, cable wire, sleeper, base plate；The U-shaped steel of arc is arranged in top, tunnel, and straight U-shaped steel is arranged in two side, tunnel, and the U-shaped steel of described arc is connected by U-shaped steel card cable with straight U-shaped steel；The U-shaped steel of arc, between straight U-shaped steel and the country rock in tunnel, it is disposed with sleeper；The U-type groove opening of the U-shaped steel of arc and straight U-shaped steel is towards sleeper；Base plate paving is bottom tunnel；Described cable wire head and the tail connect and surround the shape of tunnel cross section, are distributed in the U-type groove of the U-shaped steel of arc, in the U-type groove of straight U-shaped steel and base plate is following.
The rigid flexible system supporting construction that this utility model provides, U-shaped steel plays the effect of rigid protection, when shock loading destroys U-shaped steel, its internal cable wire plays flexible support effect, transition stage from rigid protection to flexible support, it is exactly the cushioning effect of this supporting construction impact loading, thus plays the effect of anti-impact.
Accompanying drawing explanation
Fig. 1 is this utility model structure diagram；
Fig. 2 is the layout schematic diagram of U-shaped steel and cable wire.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, rigid flexible system supporting construction, it is made up of the U-shaped steel of arc 1, straight U-shaped steel 2, U-shaped steel card cable 3, cable wire 4, sleeper 5, base plate 6；The U-shaped steel of arc 1 is arranged in top, tunnel, and straight U-shaped steel 2 is arranged in two side, tunnel, and the U-shaped steel of described arc 1 is connected by U-shaped steel card cable 3 with straight U-shaped steel 2；The U-shaped steel of arc 1, between straight U-shaped steel 2 and the country rock 7 in tunnel, it is disposed with sleeper 5；The U-type groove opening of the U-shaped steel of arc 1 and straight U-shaped steel 2 is towards sleeper 5；Base plate 6 is laid on bottom tunnel；Described cable wire 4 head and the tail connect and surround the shape of tunnel cross section, are distributed in the U-type groove of the U-shaped steel of arc 1, in the U-type groove of straight U-shaped steel 2 and base plate 6 is following.
First cable wire 4 head and the tail of certain length are connected and be arranged in the U-shaped steel of arc 1 U-type groove with straight U-shaped steel 2, U-shaped for arc steel 1 is erected at inside tunnel with straight U-shaped steel 2 distance as requested, then sleeper 5 spacing as requested is arranged between country rock 7 and the U-shaped steel of arc 1, straight U-shaped steel 2, after erection completes, cable wire 4 on the ground is laid roadway floor 6.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
