Compared with prior art, the utility model has technique effect beneficial below：
A kind of underground that is applied to provided by the utility model can resist heavily stressed air door, using rigid with flexible phase
With reference to mode, by setting crossbeam and column in rigid wall body, make the more compact structure of rigid wall, quality firmer,
Enhance the stability and robustness of rigid wall；Furthermore cushion space, i.e. flexible wall are set by the surrounding in rigid wall
Body, under the larger environment of mine pressure, the pressure that surrouding rock stress is applied to air door rigidity wall can be weakened, be not easy air door
Deformation, effectively protect the integrality of air door rigidity wall, it is ensured that the normal use of air door, extend air door uses year
Limit, reduces reconstruction and the maintenance workload of air door, has effectively ensured mine ventilation system safety and reliability.
In summary, this underground that is applied to provided by the utility model can resist heavily stressed air door, simple in construction,
It is reasonable in design, can meet all kinds of wells () under tunnel air door installation requirement, effectively prevent air door and become by surrouding rock stress
The phenomenon of shape damage occurs, and realizes the long purpose of the length of service.
Brief description of the drawings
Fig. 1 is the structural representation provided by the utility model that heavily stressed air door can be resisted suitable for underground；
Wherein, 1 is flexible wall；2 be work stone；3 be air door framework；4 be crossbeam；5 be column；6 be rigid wall.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, the utility model, which provides a kind of underground that is applied to, can resist heavily stressed air door, including air door sheet
Body, air door body are externally provided with air door framework 3, and air door framework 3 is externally provided with rigid wall 6, is all provided with above and below air door framework 3
There is crossbeam 4, connected between crossbeam 4 by several columns 5, column 5 and crossbeam 4 are arranged in rigid wall 6, rigid wall
6 are surrounded by flexible wall 1.
The utility model is combined to construct and formed by flexible wall 1 and rigid wall 6, and rigid wall 6 highlights air door knot
The stability and robustness of structure, flexible wall 1 highlight the anti-pressure ability of air door, so as to show air door under high stress
Still remaining intact property, the service life of air door is extended, ensured mine ventilation system safety and reliability.
Preferably, the crossbeam 4 uses I-steel, and column 5 uses I-steel or channel-section steel or steel pipe.It should be noted that
Crossbeam 4 and column 5 can also select the strong material of other rigidity.
Preferably, the flexible wall 1 is arranged between rigid wall 6 and roadway surrounding rock.
It is further preferred that the contact position of roadway surrounding rock and rigid wall 6 sets fluted, filling flexible material in groove
