Technical field
This utility model relates to mine and tunnel support neighborhood, relates to the improvement of U-shaped steel bracket, is particularly suited for mine
Tunnel and the supporting of Tunnel Engineering.
Background technology
In the construction of Tunnel Engineering and mine working, coming off of top board, the two big displacement deformations helped are to affect tunnel
And the subject matter that tunnel safety uses, so the supporting in tunnel and tunnel is particularly important.
At present, common tunnel and laneway support method have bolt-spary supports, bolt-mesh-spurting supporting, cable bolting, U-shaped steel supporting
And the combinative structure supporting of Bolt net and jet and U-shaped steel.For different geological conditions and rock property, available support pattern
Varied, said method all can preferably control the deformation in tunnel and tunnel, but its use be all rigidity bigger
Protect mode, it is impossible to well the stress of release country rock is so that surrouding rock stress is released, and oneself reaches balance, so tying at self
The biggest stress has been acted on when structure plays a role.
For above-mentioned technology and the deficiency of structure, it is contemplated that easy construction, cost-effective, effective grade main because of
Element, releases this utility model.This utility model is mainly in view of country rock and i.e. can reach steady statue after release certain pressure, will
U-shaped steel bracket improves, and is introduced by the damping device of automobile, is applied in combination with former U-shaped steel bracket, allows pressure fully, can resist
Vertical deformation and transversely deforming, the most again intensity of not reduction component itself, supporting effect is notable, reprocesses less, saves into
This.
Utility model content
For the deficiencies in the prior art, this utility model provides the U-shaped steel bracket of tunnel support of a kind of improvement, to realize
After the most soft just, the effect of steady supporting.
For realizing object above, this utility model is achieved by the following technical programs:
The U-shaped steel bracket of tunnel support of a kind of improvement, it is characterised in that include U-shaped steel, spring, crude steel sleeve and thin steel bushing
Cylinder.Described crude steel sleeve and thin steel bushing are respectively and fixedly installed to the open recess inwall of each described U-shaped steel and extend
Port one segment distance of described U-shaped steel, uses between described sleeve and U-shaped steel and is welded to connect.Described thin steel bushing is inserted in described
In the endoporus of crude steel sleeve and completely laminating but the bottom be not exclusively inserted in described crude steel sleeve, described thin steel bushing outer wall with
Described crude steel sleeve lining frosted is with increasing friction force.Do not contact outside the described crude steel sleeve spliced with thin steel bushing around
One encloses described spring, two described U-shaped steel that described spring will weld together with described crude steel sleeve and thin steel bushing afterbody
It is connected so that it is become a common stress of entirety.Total is spliced by said structure described in two groups, two groups of structures
Between connected mode identical with aforesaid way.
Further, described U-shaped steel specification uses U18-U29, a length of 800-1200mm.
Further, described crude steel sleeve and a length of 200-400mm of thin steel bushing, end, described crude steel sleeve one end
Perforate, its aperture is 80-150mm, and the degree of depth is 100-200mm, and described crude steel sleeve diameter is 110-180mm, described thin steel bushing
Cylinder is solid, its a diameter of 70-140mm, and crude steel sleeve processes with thin steel bushing contact surface frosted.
Further, described spring is selected and is mainly comprised the compression spring that material is piano wire, and external diameter is 120-200mm,
Drift is 20-40mm, and it end with described U-shaped steel is welded to connect respectively.
This utility model provides the U-shaped steel bracket of tunnel support of a kind of improvement, and by U-shaped steel, steel bushing thick, thin also has
Being applied in combination of spring, makes them become a complete stress system, and it not only possesses requirement of strength, is provided simultaneously with certain
Flexibility allow pressure energy power, can effectively contain the deformation in tunnel and tunnel.The most U-shaped steel uses extensively because of it, and thin-walled is conducted oneself with dignity
Gently, function admirable.
