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
With the fast development of transportation, leap that China builds in the recent period is opened the navigation or air flight the large-scale of rivers, port area and straits
Bridge quantity progressively increases, and the ships quantity on navigation channel is also continuously increased and ship type tends in maximizing so that bridge and logical
The contradiction navigated between oceangoing ship is increasingly prominent, and the accident of therefore ship collision bridge pier is also continuously increased.The shock institute to bridge for the ship
The structural damage causing reduces bearing capacity within projected life for the bridge and durability to a certain extent, results even in
The collapsing of total.
In prior art, pier anticollision body relies on inner cushioning material to carry out buffering energy-absorbing, and the external circle of anticollision often occurs
Situation about thoroughly damaging, maintenance and repair consuming is higher, and it is anti-collision bridge pier field skill that the external circle of what kind of anticollision is hardly damaged relatively
Art personnel faced by a significant problem.
Content of the invention
The technical problem to be solved in the present invention is: overcomes the shortcomings of that in prior art, conventional crash cognition is easily damaged, carries
For a kind of pier anticollision body.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pier anticollision body it is characterised in that: described
Anti- collision body surrounds bridge pier, including 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；
Some grooves are offered on described outer ring, described steel cable is wrapped on outer ring, and steel cable two ends are fixed on outer ring vertically.
For improving the uniformity of outer ring stress, preferably, described some grooves are uniformly arranged along outer ring circumference.
Preferably, described outer ring is fiber reinforced plastic barrel, described inner ring is metal cylinder or armored concrete cylinder.
Preferably, described packing material is polyurethane foam, polyurethane foam has excellent buffering energy-absorbing function.
For improving steel cable service life, preferably, there is antirust coat outside described steel cable.
The invention has the beneficial effects as follows, the present invention will open up some grooves on external for anticollision circle, and on the external circle of anticollision
It is wound around steel cable, so contact, in ship collision bridge pier, the steel cable being wrapped on outer ring first, fluted due to opening up on outer ring,
Steel cable, to contract, effectively can carry out buffering energy-absorbing to ship impact force, impact force is distributed to anti-collision body by steel cable simultaneously
Each position, it is to avoid when ship collision conventional crash encloses in vitro, impact force concentrates on the situation of rum point, can greatly reduce
The probability that anti-collision body damages.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is apparatus of the present invention top view；
Fig. 2 is apparatus of the present invention sectional view；
In figure 1. bridge pier, 2. anti-collision body, 21. outer rings, 211. grooves, 22. inner rings, 23. packing materials, 24. gripper shoes,
3. steel cable.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only with
Illustration illustrates the basic structure of the present invention, and therefore it only shows the composition 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, including 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 on outer ring 21 He
Between inner ring 22；Some grooves 211 are offered on described outer ring 21, described steel cable 3 is wrapped on outer ring 21, steel vertically
3 two ends of restricting are fixed on outer ring 21.
Further, described some grooves 211 are uniformly arranged along outer ring 21 circumference.Described outer ring 21 is glass fibre reinforced plastic cylinder
Body, described inner ring 22 is metal cylinder or armored concrete cylinder.Described packing material 23 is polyurethane foam.Described
Outside steel cable 3, there is antirust coat.
The present invention will open up some grooves 211 on anti-collision body 2 outer ring 21, and is wound around steel cable 3 on anti-collision body 2 outer ring 21,
So contact the steel cable 3 being wrapped on outer ring 21 in ship collision bridge pier 1 first, open up fluted 211 due on outer ring 21,
Steel cable 3, to contract, effectively can carry out buffering energy-absorbing to ship impact force, and impact force is distributed to anti-collision body 2 by steel cable 3 simultaneously
Each position, it is to avoid the situation that impact force during ship collision conventional crash body 2 outer ring concentrates on rum point, Neng Gou great occur
The big probability reducing anti-collision body 2 damage.
