Description
Technical field
The present invention relates to water safety protection technology fields, and in particular to a kind of water filling type anti-collision ring and has the anti-collision ring
Bridge pier.
Background technique
It is well known that vessel bump bridge accident is being constantly occurring always all over the world, by the people caused by vessel bump bridge accident
Member's injures and deaths, property loss and environmental disruption are surprising.Many vessel bump bridge accidents gently then lose tens of thousands of members, and heavy then personnel hurt
It dies, lose with millions of even more, a large amount of indirect loss is even more to be difficult to calculate.Therefore Anticollision Measures are taken especially to bridge
Necessity, basic goal are: it prevents bridge recurring structure due to ship impact force from damaging, while protecting ship as much as possible, it will
Loss is reduced to a minimum.
Currently, being applied to navigation channel bridge pier periphery is arranged anti-collision ring, there is anti-collision ring based on rigid material and with software
Anti-collision ring based on material.Anti-collision ring such as steel jacket box, flexible steel wire ring anti-collision ring and glass reinforced plastic based on rigid material
Composite anti-collision circle etc., after colliding, main structure can not be replied;These anti-collision rings primary collision generation after, compared with
Small deformation can be reused after must carrying out monomer replacement when must pass through external force reparation, large area deformation or damage, maintenance difficult
Cost is big and maintenance rate is high.
Anti-collision ring such as bulk solid filled-type soft rubber anti-collision ring based on soft material, can effectively solve main body knot
The non-response problem of structure;After primary collision occurs, main structure is not required to repair substantially, it is only necessary to mend to the bulk solid of crushing
Fill out, other attached circles repaired and can be come into operation, easy to maintenance at low cost and maintenance rate is low, but however bulk solid fill out
Type software anti-collision ring is filled, bulk solid mechanical property may be with using time and use environment to change, and this property makes
Anti-collision ring energy dissipation capacity with use the time reduce and more difficult accurate prediction.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of water filling type anti-collision ring and with this

Based on the above technical solution, main chamber wall has the overcoating soft material layer of separation double-layer structural and seals soft
Body layer;The sealing soft material layer forms air cavity close to the air cavity wall and between the air cavity wall.
Based on the above technical solution, the water nozzle be set to every group of adjacent air cavity unit between, directly with it is described
The water cavity formed on the inside of main chamber wall is connected.
Based on the above technical solution, the bluff piece of flake type distribution is removably coated on the outside of main chamber wall.
Based on the above technical solution, friction plate has been removably installed on the outside of the bluff piece.
Based on the above technical solution, main chamber wall and the air cavity wall are bone made of fiber reinforced rubber
Frame.
To achieve the above objectives, the technical solution that the present invention takes second is that:
A kind of bridge pier with above-mentioned anti-collision ring, the anti-collision unit, which successively joins end to end, to be sheathed on bridge pier, and is suspended
In on the water surface.
Compared with the prior art, the advantages of the present invention are as follows:
The present invention provides a kind of water filling type anti-collision ring, and the structure based on main chamber wall is used on main chamber wall equipped with water nozzle
It is filled the water to water cavity and buffering collision of closed is sprayed water into air when anti-collision ring is hit;Secondly, being aided with air cavity wall is time main body knot
Structure, the air cavity between the gentle cavity wall of main chamber wall fill air, when the anti-collision ring placed outside bridge pier is in collision initial stage, the main structure
A small amount of radial compressions occur, air cavity accumulation of energy at this time and buffering collision of closed, as decrement increases, the interior pressure of water cavity on the inside of air cavity wall
Increase, the injection outward of water nozzle high speed takes away collision energy, while discharging the interior pressure of water cavity, and the main structure is software material
Matter, can all be compressed and main structure is not destroyed;Again, main chamber wall overcoating distributed bluff piece, friction plate, primary
After collision occurs, bluff piece, the friction plate of local damage are replaced, and into water cavity after injection fresh water, i.e., it is reusable,
Therefore, water filling type anti-collision ring provided by the invention maintenance rate at low cost easy to maintenance is low, more economy and the feature of environmental protection, and uses
Energy-dissipating property keeps stablizing in the process, the bridge-collision-avoidance protection for the following ship of inland river 10,000 tons that is suitable for opening the navigation or air flight especially.
