Abstract
The invention provides a collision avoidance body of a pier. The collision avoidance body surrounds the pier and comprises an outer ring, an inner ring, a filling material, a supporting plate and a steel rope; the filling material is arranged between the outer ring and the inner ring and the supporting plate is supported between the outer ring and the inner ring; a plurality of grooves are formed in the outer ring in the axial direction, the steel rope is wound around the outer ring, and the two ends of the steel rope are fixed on the outer ring. The collision avoidance body of the pier is characterized in that the plurality of grooves are formed in the outer ring of the collision avoidance body and the outer ring of the collision avoidance body is wound with the steel rope, so that, when a ship hits against the pier, the ship firstly contacts with the steel rope wound around the outer ring, as the grooves are formed in the outer ring, the steel rope shrinks inwards and thus is capable of effectively buffering the impact force of the ship and absorbing energy, and meanwhile, the impact force is dispersed to each part of the collision avoidance body by virtue of the steel rope so that the case that the impact force is concentrated at the hitting point when the ship hits against the outer ring of a traditional collision avoidance body is avoided and the probability that the collision avoidance body is damaged can be greatly reduced.
Description
Technical field
The present invention relates to anti-collision bridge pier field, especially a kind of pier anticollision body.
Background technology
Along with the fast development of transportation, the large bridge quantity in leap navigation rivers, port district and straits that China builds in the recent period progressively increases, and ships quantity on navigation channel also constantly increases and ship type is tending towards in maximization, make the contradiction between bridge and current boats and ships increasingly outstanding, therefore the accident of ship collision bridge pier also constantly increases.The structural damage that boats and ships cause the shock of bridge has reduced supporting capacity and the durability of bridge within projected life to a certain extent, even can cause collapsing of total.
In prior art, pier anticollision body relies on internal damping material to carry out buffering energy-absorbing; crashproof external circle often there will be the situation of thorough damage; maintenance and repair expend higher, and what kind of crashproof external circle is relatively not fragile is the significant problem that anti-collision bridge pier those skilled in the art face.
Summary of the invention
The technical problem to be solved in the present invention is: overcome traditional crashproof cognition in prior art and hold flimsy deficiency, a kind of pier anticollision body is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pier anticollision body, is characterized in that: described anti-collision body surrounds bridge pier, comprises outer ring, inner ring, packing material, gripper shoe and steel cable;
Described packing material is filled between outer ring and inner ring, and described gripper shoe is supported between outer ring and inner ring; On described outer ring, offer vertically some grooves, described steel cable is wrapped on outer ring, and steel cable two ends are fixed on outer ring.
For improving outer ring stressed uniformity, as preferably, described some grooves circumferentially evenly arrange along outer ring.
As preferably, described outer ring is fiber reinforced plastic barrel, and described inner ring is metal cylinder or steel concrete cylindrical shell.
As preferably, described packing material is polyurethane foam, and polyurethane foam has good buffering energy-absorbing function.
For improving steel cable application life, as preferably, described steel cable has antirust coat outward.
The invention has the beneficial effects as follows, the present invention will offer some grooves on crashproof external circle, and be wound around steel cable on crashproof external circle, in the time of ship collision bridge pier, first contact like this steel cable being wrapped on outer ring, owing to offering groove on outer ring, steel cable inwardly shrinks, can effectively carry out buffering energy-absorbing to ship impact force, steel cable is distributed to impact at each position of anti-collision body simultaneously, while having avoided the crashproof external circle of ship collision tradition, impact concentrates on the situation of rum point, can greatly reduce the probability that anti-collision body damages.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of pier anticollision body, described anti-collision body 2 surrounds bridge pier 1, comprises outer ring 21, inner ring 22, packing material 23, gripper shoe 24 and steel cable 3;
Described packing material 23 is filled between outer ring 21 and inner ring 22, and described gripper shoe 24 is supported between outer ring 21 and inner ring 22; On described outer ring 21, offer vertically some grooves 211, described steel cable 3 is wrapped on outer ring 21, and steel cable 3 two ends are fixed on outer ring 21.
Further, described some grooves 211 circumferentially evenly arrange along outer ring 21.Described outer ring 21 is fiber reinforced plastic barrel, and described inner ring 22 is metal cylinder or steel concrete cylindrical shell.Described packing material 23 is polyurethane foam.Outside described steel cable 3, there is antirust coat.
The present invention will offer some grooves 211 on anti-collision body 2 outer rings 21, and be wound around steel cable 3 on anti-collision body 2 outer rings 21, in the time of ship collision bridge pier 1, first contact like this steel cable 3 being wrapped on outer ring 21, owing to offering groove 211 on outer ring 21, steel cable 3 inwardly shrinks, can effectively carry out buffering energy-absorbing to ship impact force, steel cable 3 is distributed to impact at each position of anti-collision body 2 simultaneously, while having avoided occurring the ship collision anti-collision body of tradition 2 outer ring, impact concentrates on the situation of rum point, can greatly reduce the probability that anti-collision body 2 damages.
