Abstract
The invention relates to the technical field of safety protection in water construction, in particular to a passive anti-collision protection plate for a pier. The passive anti-collision protection plate for the pier comprises a plurality of anti-collision plates which are attached and fixed to the side wall of the pier through winding mechanisms. Each anti-collision plate comprises a plurality of composite material plates which are overlaid together, a plurality of elastic buffering blocks are arranged between the adjacent composite material plates and enable a plurality of energy dissipation gaps to be formed between the composite material plates, the composite material plates of each anti-collision plate are fixedly connected through the winding mechanisms, and the overlaying direction of the composite material plates of each anti-collision plate is perpendicular to the direction of the side surface of the pier. According to the passive anti-collision protection plate for the pier, the anti-collision plates are wound around the side wall of the pier and can effectively protect the pier when a ship collides with the pier; the composite material plates are fixed through glass fiber ropes, the whole anti-collision plates are made of non-metallic materials and have high corrosion resistance, and therefore the service life of the passive anti-collision protection plate for the pier is effectively prolonged.
Description
Technical field
The present invention relates to aquatic building safety protection technique field, the passive crashproof backplate of especially a kind of bridge pier, the specifically energy dissipator of a kind of bridge pier for bridge, bridge tower, cushion cap, harbour protector inner side.
Background technology
Ship (car) hits bridge accident and constantly, is occurring all over the world always, and the frequency that ship hits bridge accident is higher more than our imagination.It is surprising by ship, hitting casualties, property loss and the environmental disruption that bridge accident causes.A lot of ships hit bridge accident and gently lose tens thousand of units, and heavy casualties is lost in millions of, tens million of even multi-million dollars, and a large amount of indirect losses is difficult to calculate especially.Therefore to bridge, take Anticollision Measures particularly necessary, its basic goal is: prevent bridge chance boats and ships (vehicle) impact and recurring structure breaking-up, the while is protected boats and ships (vehicle) as much as possible, and loss is reduced to a minimum.
Through years of researches, use, occurred the multiple pier anticollision facility for bridge collision both at home and abroad, but its basic principle designs based on energy absorption, momentum buffering, every kind of anti-collision facility has its feature and service condition.Anti-collision facility is mainly direct-type specifically, and 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.But existing crashproof bumper ring self is destroyed after being clashed into, remaining power all concentrates on bridge pier, can not well play the effect of protection bridge pier.Meanwhile, the connector of existing crashproof backplate is all to adopt metal species connector to connect, its corrosion-resistant, and application life is short.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve existing crashproof bumper ring energy dissipating ability after being clashed into, can not well play the problem of the effect of protection bridge pier, the invention provides the passive crashproof backplate of a kind of bridge pier, by Crashworthy plate being wrapped in to bridge pier sidewall, Crashworthy plate is being arranged alternately by composite panel and elastic buffer piece, after being subject to hull shock, first composite panel compressing elastic buffer piece carries out the energy dissipating of the first order, simultaneously, the protection energy dissipating of the formation second level, space between composite panel, the destruction of composite material self forms third level energy dissipating, can form a kind of effective protection to bridge pier.
The technical solution adopted for the present invention to solve the technical problems is: the passive crashproof backplate of a kind of bridge pier, comprise: the Crashworthy plate that several and the laminating of bridge pier sidewall arrange, described Crashworthy plate is fixed on bridge pier sidewall by winding mechanism, described Crashworthy plate comprises some composite panels that are superimposed, between adjacent composite panel, be provided with some elastic buffer pieces, described elastic buffer piece makes to form between composite panel some energy dissipatings space, between described some composite panels, by winding mechanism, be fixedly connected with, the Direction of superposition of the composite panel of described Crashworthy plate and bridge pier lateral vertical.
Particularly, described composite panel is glass fibre reinforced composion plate.
As preferably, described glass fibre reinforced composion is a kind of in unsaturated-resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A-type resin, reactive resin, and fiber is a kind of of glass fiber, carbon fiber, aramid fiber or composite fibre.
As preferably, described elastic buffer piece is caoutchouc elasticity buffer stopper.
As preferably, described winding mechanism is glass cord.
The invention has the beneficial effects as follows: the passive crashproof backplate of a kind of bridge pier provided by the invention; by Crashworthy plate being wrapped in to bridge pier sidewall; Crashworthy plate is being arranged alternately by composite panel and elastic buffer piece; after being subject to hull shock; first composite panel compressing elastic buffer piece carries out the energy dissipating of the first order, meanwhile, and the protection energy dissipating of the formation second level, space between composite panel; the destruction of composite material self forms third level energy dissipating, can form a kind of effective protection to bridge pier.Meanwhile, composite panel is fixed by glass fiber rope, and whole Crashworthy plate all adopts nonmetals, has higher corrosion resistance, has effectively extended the application life of the passive crashproof backplate of bridge pier.
