Description
Technical field
The present invention relates to the hangar tunnel of a kind of mountain highway guard technology more particularly to a kind of anti-rock-fall impact energy dissipating pad of band and
Anti- rock-fall impact energy dissipating pad.
Background technique
China's mountain highway mileage is longer, wherein taking place frequently section there are a large amount of collapse rock-fall disasters；In order to guarantee mountain area public affairs
The current safety on road, the prior art build hangar tunnel on mountain highway generally to defend collapse rock-fall disaster；To improve hangar tunnel
Energy-dissipating structure generally will be also arranged in protective performance on hangar tunnel, and to absorb or consume the impact energy of falling rocks, typical structure is such as
" a kind of energy dissipating hangar tunnel and its energy dissipating support (No. 201010242005.7 Chinese patent) "；The problem is that: it is existing to disappear
Energy organization plan is only suitable for setting when newly-built hangar tunnel mostly, is not used to in-service hangar tunnel transformation.
Summary of the invention
For the problems in background technique, the invention proposes a kind of anti-rock-fall impact energy dissipatings for shed tunnel top protection
Pad, innovation are: the anti-rock-fall impact energy dissipating pad is made of base, multiple energy dissipating bottles, more springs and cover board；
The energy dissipating bottle is the ampuliform structural body that upper end diameter is less than lower end diameter, middle part is swelled outward；Energy dissipating bottle is arranged in base
On the upper side of layer, energy dissipating bottom of bottle portion is fixedly connected with the base；Multiple energy dissipating bottles are distributed by matrix form；
The cover board is arranged above base, and cover board is parallel with base, and multiple through-holes are provided on cover board；The socket of energy dissipating bottle upper end
In through-holes and fixed, multiple through-holes and multiple energy dissipating bottles correspond；
The spring is arranged between base and cover board, and the axial direction of spring is vertical with the upper side of base, the lower end of spring and base
Layer is fixedly connected, and the upper end of spring is fixedly connected with cover board；More springs are distributed by matrix form；
Between diagonally adjacent two adjacent energy dissipating bottles of matrix, all there is a spring；In the diagonal of matrix
Between upper two adjacent springs, all there is an energy dissipating bottle；
The base, energy dissipating Bottle and closure plate are all made of polyester material production；The thickness of base is greater than the thickness of cover board.
Based on aforementioned schemes, the invention also provides a kind of hangar tunnels of the anti-rock-fall impact energy dissipating pad of band, including build and be close to
Hangar tunnel on the highway of mountain, innovation are: anti-rock-fall impact energy dissipating pad is provided on the top surface of the hangar tunnel；
The structure of anti-rock-fall impact energy dissipating pad is as previously described；Constitute base, energy dissipating bottle, spring and the lid of anti-rock-fall impact energy dissipating pad
Plate is prefabricated component；The base is arranged on the top surface of hangar tunnel, and energy dissipating bottle, spring and cover board are arranged by aforementioned schemes in base
On.
The principle of the present invention is: when there is falling rocks to fall, since energy dissipating bottle is hollow structure, and the pressure around falling rocks downside
Contracting air can be absorbed by energy dissipating bottle, be weakened impact energy caused by falling rocks, since base, energy dissipating Bottle and closure plate are all made of
Polyester material production, base, energy dissipating Bottle and closure plate all have preferable deformability, and falling rocks is contacted with anti-rock-fall impact energy dissipating pad
Afterwards, base, energy dissipating bottle, spring and cover board can play assimilation effect to the impact force of falling rocks, and after rock-fall impact, spring can
To jack up cover board, so that energy dissipating bottle be made to reply deformation as early as possible, continue to meet rock-fall impact next time；Due to being provided with energy dissipating
Bottle, the present invention can not only play the energy-absorbing effect of elastic insert structure, moreover it is possible to in percussion as caused by compressed air
Weakening effect is played in part, improves the shock resistance of safeguard structure；In addition, constituting the base of anti-rock-fall impact energy dissipating pad, disappearing
Can bottle, spring and cover board can the pre-production in factory, then on-site assembly is at anti-rock-fall impact energy dissipating pad, is particularly suitable for pair
In-service hangar tunnel is transformed, rebuilding construction very simple.
The method have the benefit that: propose the hangar tunnel and anti-rock-fall impact of a kind of anti-rock-fall impact energy dissipating pad of band
Energy dissipating pad, the program can effectively improve protection effect, be especially suitable for being transformed upgrading to in-service hangar tunnel.
