Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figs. 1-2, including bottom plate 1, which is characterized in that stabilizer blade 2 there are two 1 bottom of bottom plate is fixed,
The 1 inside both ends of bottom plate are fixed with side support bar 6, institute on the bottom support rod 14 respectively inserted with bottom support rod 14
It states and is provided with pedestal 3 on bottom plate 1, fixed there are two transverse hydraulic device 4 on the pedestal 3, two transverse hydraulic devices 4 are in mirror
The hydraulic telescopic rod 5 of face setting, 6 side of side support bar and transverse hydraulic device 4 is fixed by pipe clamp 8, the side support bar 6
It is fixedly arranged above vertical hydraulic press 7, the hydraulic telescopic rod 5 and top supporting rod 10 of the vertical hydraulic press 7 are solid by pipe clamp 8
Fixed, the top supporting rod 10 of two sides is inserted into inside mandril 13.
In order to keep this kind of tunnel support device easy to use, the top supporting rod 10 is in bending, bending in the outer part
Part is fitted with yielding rubber 12, and the side support bar 6 is T-shaped, the groove 16 on side support bar bottom and bottom support rod 14
Engaging, and it is fixed by bolt 15 and nut 17, and the top supporting rod 10,6 corner of the side support bar are welded with connection
Bar 9, the top supporting rod 10,6 corner of the side support bar are provided with mounting hole 11, totally four mounting holes 11.
The structure design of the utility model is reasonable, which is put in tunnel by when use, passes through starting bottom
Two transverse hydraulic devices 4, two transverse hydraulic devices 4 drive hydraulic telescopic rods 5 to push to two sides, allow the side support bar 6 of two sides to
Side is mobile, at this point, side support bar 6 is while pushing, since the bottom support rod 14 of side support bar 6 and bottom is fixed, bottom
Portion's support rod 14 is stretched out out of bottom plate 1, and bottom support rod 14 plays a supporting role to side support bar 6, and the top braces at top
Bar 10 is stretched out out of mandril 13, while adjusting vertical hydraulic press 7, and vertical hydraulic press 7 drives hydraulic telescopic rod 5 to push to top,
Since the top in tunnel is in arc-shaped, for top supporting rod 10 while hydraulic telescopic rod 5 pushes up, top supporting rod 10 is curved
It is contacted at the top of folding part branch and tunnel, 12 quality of yielding rubber of bending place is more soft, can satisfy roadway deformation amount
Error, two yielding rubbers 12 tentatively support tunnel top.It, thus can be in tunnel since tunnel has certain length
It is interior to be laid with multiple support devices, one support device can be set every a distance by tunnel physical length, when device is arranged
After good, can by four mounting holes 11 on top supporting rod 10 and side support bar 6, between every two support device by steel pipe into
Row connection, allows multiple support devices to form a complete support system, when two, top mounting hole 11 and another support
After two mounting holes 11 of device are connected by steel pipe, shield top anchor pole can be set up on two steel pipes, in the shielding of shield top anchor pole
Under, advance support steel pipe is set, using the steel pipe of 34 × 2800mm of Φ, is arranged more than the shoulder nest of tunnel, spacing 300mm arrangement,
Angle is by roadway gradient to 3~5 ° of vertical angle, exposed ≯ 400mm, and every circulation specification sets advance support steel pipe, with controlroof
Broken region, big gun pick or fully mechanized footage arrange anchor pole, reserve the advanced steel pipe of 800mm, reinforce top plate bearing capacity, prevent top plate from emitting
It falls, and takes reinforced mesh between the steel pipe of side two, then the gunite concrete on reinforced mesh, secondary anchor net is taken to tunnel
Supporting operation is infused, due to keeping certain distance between top and the inner wall in lateral distance tunnel, secondary anchor net is being carried out to tunnel
When infusing supporting, there is enough operating spaces, allow tunnel have it is certain allow compressive strain space, prevent from seriously causing to influence because deforming
Safe handling.Wherein it is fixedly connected between side support bar 6 and bottom support rod 14 by bolt 15 and nut 17, and hydraulic press
It is fixed further through pipe clamp 8 between hydraulic telescopic rod 5 and support rod, in practical operation transportational process, support device can be torn open
Unload into several structures, for transport and installation both provide it is convenient.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
