Use through years of researches, occurred the multiple pier anticollision facility for bridge collision both at home and abroad, but its general principle designs based on energy absorption, momentum buffering, every kind of anti-collision facility has its feature and service condition.Anti-collision facility is seen and is divided into two large classes specifically: one is indirect type, and its feature is: outside bridge pier, separately establish anti-collision facility, the not direct capacity of bridge pier, allows bridge pier thoroughly avoid ship collision problem.As: pile group mode, shell are built husky cofferdam mode, man-made island mode etc., are generally applicable to that water is shallow, the good occasion of geological condition.Although indirect type avoiding collision is put things right once and for all, and can affect navigation channel, and usually because not possessing two, the too high or condition of cost abandons.Two is direct-type, and its feature is: power acts directly on bridge pier after buffering, as protects string mode, rope mode of texturing, padded coaming implementation, fender system engineering mode and fixing or floating casing anti-collision facility etc.The occasion that general use is narrower in navigation channel, water is darker, expenditure of construction is economized conventionally, and civilwork engineering quantity is little.As: Zhanjiang Bay Bridge, Changjiang River Bridge Shanghai adopt steel box anticollision device, collision-prevention device, this energy-dissipating installation utilizes the damaged energy dissipating of steel plastic strain, in the time of ship collision steel jacket box anticollision device, collision-prevention device, there is large distortion in anti-collision structure skin discontinuous (interruption) structural steel and iron, has absorbed local collision energy, and extended time of contact, impact peak value is minimized, simultaneously due to malformation and interaction, thereby stir fore direction, reduced boats and ships and interstructural energy exchange.But steel jacket box bears single conventionally to be clashed into, and after damage, maintenance is more difficult; Hull subject to damage while simultaneously collision; Steel easy-to-rust in water throughout the year in addition.Maintenance cost is higher, therefore it is extremely urgent to adopt new material to design and develop Novel crashproof system.
Utility model content
The technical problems to be solved in the utility model is: the crashproof heterodyne existing in order to solve existing anticollision device of pier, the problem that maintenance cost is high, the utility model provides a kind of bridge pier protection guard, in the time being subject to clashing into, first consume a large amount of merits when the plastic strain of housing, carry out after first order energy dissipating at housing, energy dissipating air bag in housing can carry out secondary energy dissipating to clashing into, crashproof effective, can effectively reduce the impact of boats and ships to bridge pier, and each energy dissipating post is separate unit, convenient for maintaining.
The utility model solves the technical scheme that its technical problem adopts: a kind of bridge pier protection guard, comprise some around being arranged on bridge pier anticollision energy eliminating post around, the axis of energy dissipating post is parallel with the axis of bridge pier, and described energy dissipating post comprises housing and is arranged on the energy dissipating air bag in housing cavity.
In the time being subject to clashing into, first consume a large amount of merits when the plastic strain of housing, carry out after first order energy dissipating at housing, the energy dissipating air bag in housing can carry out secondary energy dissipating to clashing into.
Particularly, described energy dissipating air bag comprises rubber layer, energy dissipating material layer and rubber layer from outside to inside successively.
As preferably, the space between described housing and energy dissipating air bag is filled with energy dissipating material.
Particularly, described energy dissipating material is the one in polyurethane foam, glass fiber, carbon fiber, aramid fiber, composite fibre.
Particularly, described housing is glass fibre reinforced composion, and described glass fibre reinforced composion case material is the one in unsaturated-resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A-type resin, reactive resin.
Particularly, described housing is provided with the filler opening of some axis directions, is filled with polyurethane foam, glass fiber, carbon fiber, aramid fiber or composite fibre in described filler opening.
In the time that energy dissipating post is subject to impact, because a filler opening outer wall in energy dissipating post is cross-linked with each other, impact can be transmitted and be held rapidly, prevents that impact is too concentrated.
Particularly, described filler opening is honeycomb type filler opening.
Honeycomb type filler opening structural strength is high, and large for filling the space of energy dissipating material, in identical packing space, have and can fill more energy dissipating material, make its structure not yielding in the time being subject to clashing into, overall structure intensity on stress is larger, and structural stability is stronger.
