Abstract
The invention relates to an anticollision buffer ring for a bridge pier. The buffer ring comprises an anticollision buffer ring body arranged around the bridge pier; the anticollision buffer ring body comprises a plurality of buffer units connected through lock chains; the buffer units comprise a plurality of energy dissipation posts connected through the lock chains and a plurality of cylindrical fenders uniformly distributed on the energy dissipation posts, the axes of the fenders and the axes of the energy dissipation posts are vertically intersected, a plurality of axial filling holes are formed in the energy dissipation posts and are filled with energy dissipation materials, and the fenders comprise shells and rubber posts arranged in the shells. According to the anticollision buffer ring for the bridge pier, the energy dissipation can be performed by the plasticity and elastic deformation in the process of impacting, and a great quantity of impact force can be cut down to enable a ship to tend to stop or stop; meanwhile, a plurality of buffer units are connected through the lock chains, and the buffer ring can be maintained by changing single buffer unit, so that the maintenance cost is low.
Description
Technical field
The present invention relates to aquatic building safety protection technique field, especially a pier anticollision bumper ring, specifically a kind of for cushioning the protector of the impact force that the aquatic buildings such as the bridge pier, bridge tower, cushion cap, harbour of all kinds of bridges are subject in shock accident.
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 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.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, usually adopts steel jacket box, clashes into but steel jacket box bears single conventionally, 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.
Summary of the invention
The technical problem to be solved in the present invention is: the high problem of crashproof heterodyne, maintenance cost existing in order to solve existing anticollision device of pier, the invention provides a kind of pier anticollision bumper ring, by several fenders are set on energy dissipating post, in the time occurring to clash into, plasticity and elastic deformation by self consume energy, subdue a large amount of impacts, make ship be tending towards stopping or stopping, and several buffer cells are to connect by chain, can safeguard by changing single buffer cell, maintenance cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pier anticollision bumper ring, comprise around being arranged on bridge pier crashproof bumper ring around, crashproof bumper ring comprises the buffer cell that several connect by chain, it is characterized in that: described buffer cell comprises the some energy dissipating posts that connect by chain, and be distributed on the some cylindricality fenders on described energy dissipating post, described fender axis and described energy dissipating mast axis intersect vertically, in described energy dissipating post, be provided with the filler opening of some axis directions, in described filler opening, be filled with energy dissipating material, described fender comprises shell and is arranged on the rubber column in shell.
As preferably, described filler opening is triangle, quadrangle, hexagon or circle.
Particularly, described energy dissipating material is polyurethane foam, haydite, glass fiber, carbon fiber, aramid fiber or composite fibre.。
As preferably, described shell and described energy dissipating post are one-body molded.
As preferably, described rubber column center offers circular hole, in described circular hole, fills out and is provided with glass fibre reinforced composion.
As preferably, the Shell Materials of described energy dissipating column material and described fender is glass fibre reinforced composion.
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.
The invention has the beneficial effects as follows, the invention provides a kind of pier anticollision bumper ring, by several fenders are set on energy dissipating post, in the time occurring to clash into, consume energy by self plasticity and elastic deformation,
Subdue a large amount of impacts, make ship be tending towards stopping or stopping, and several buffer cells are to connect by chain, can safeguard by changing single buffer cell, maintenance cost is low, and crashproof bumper ring is completed by composite material vacuum introducing technology one, device designs according to different types and environment, can be along with the rising whereabouts free floating of water level in ocean, material is acidproof, alkaline-resisting, crashproof, energy dissipating reaches 70%, Use Limitation 50 years.
