Abstract
The invention relates to the technical field of overwater construction safety protection, in particular to a passively crashproof energy dissipation guard bar for a pier. The passively crashproof energy dissipation guard bar for the pier comprises a plurality of crashproof columns vertically arranged around the pier. The crashproof columns are fixedly wound around the pier through glass fiber ropes. Each crashproof column comprises three columnar energy dissipation bodies made of composite materials, the columnar energy dissipation bodies are arranged in a pairwise tangent mode, and the three columnar energy dissipation bodies are fixedly arranged through the glass fiber winding ropes. According to the passively crashproof energy dissipation guard bar for the pier, the multiple crashproof columns are vertically arranged around the pier through the glass fiber winding ropes, each crashproof column comprises the three columnar energy dissipation bodies made of the composite materials, the columnar energy dissipation bodies are arranged in a pairwise tangent mode and are fixedly arranged through the glass fiber winding ropes, effective protection of the pier is achieved, composite material plates are fixed through the glass fiber ropes, a whole crashproof plate is made of non-metal materials and has higher corrosion resistance, and the service life of the crashproof columns of the pier is prolonged effectively.
Description
Technical field
The present invention relates to aquatic building safety protection technique field, the passive anticollision energy eliminating guardrail 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 is constantly occurring all over the world always, and the frequency that ship hits bridge accident is higher more than our imagination.It is surprising hitting by ship 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 take Anticollision Measures particularly necessary to bridge, 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.
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 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 a kind of pier anticollision cylinder, around bridge pier, be wound around several bumping posts by glass cord, each bumping post comprises three composite material column damping bodies, three composite material column damping body tangent settings between two, and be fixedly installed by glass fiber winding rope, be subject to after hull shock, first the composite material column damping body that contacts at first hull is squeezed, motion, glass fiber winding rope forms first order energy dissipating, simultaneously, the destruction of composite material column damping body self forms second 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 anticollision energy eliminating guardrail of a kind of bridge pier, comprise: several are vertically arranged on bridge pier bumping post around, described bumping post is fastened around bridge pier by glass cord, described bumping post comprises three composite material column damping bodies, the tangent setting between two of described column damping body, described three column damping bodies are fixedly installed by glass fiber winding rope.
As preferably, described column damping body is glass fibre reinforced composion column damping body.
As preferably, described glass fibre reinforced composion is the one in unsaturated-resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A-type resin, reactive resin, and fiber is the one of glass fiber, carbon fiber, aramid fiber or composite fibre.
As preferably, in described column damping body, be provided with some axial filler openings, in described filler opening, be filled with energy dissipating material.
As preferably, described energy dissipating material is polyurethane foam, haydite, glass fiber, carbon fiber, aramid fiber or composite fibre.As preferably, described column damping body is glass fibre reinforced composion column damping body.
The invention has the beneficial effects as follows: the invention provides a kind of pier anticollision cylinder, around bridge pier, be wound around several bumping posts by glass cord, each bumping post comprises three composite material column damping bodies, three composite material column damping body tangent settings between two, and be fixedly installed by glass fiber winding rope, be subject to after hull shock, first the composite material column damping body that contacts at first hull is squeezed, motion, glass fiber winding rope forms first order energy dissipating, simultaneously, the destruction of composite material column damping body self forms second level energy dissipating, can form a kind of effective protection to bridge pier, composite panel is fixed by glass fiber rope, whole Crashworthy plate all adopts nonmetals, there is higher corrosion resistance, effectively extend the application life of pier anticollision cylinder.
