Abstract
The utility model discloses a floating flexible steel composite material bridge anti-collision structure. The structure comprises a plurality of steel pipe brackets, wherein hoisting rings are arranged on the tops of the steel pipe brackets; the steel pipe brackets are connected together through steel strands wound on the hoisting rings; steel pipes are filled with an energy-absorbing material; an anti-collision bag is arranged on the outer sides of the steel pipe brackets, and is filled with a buffering material; an arc-shaped rubber layer is formed on the outer side of the anti-collision bag; a suspension air bag is arranged in the middle of the steel pipe brackets, and is filled with air; a buffering bag is arranged on the inner sides of the steel pipe brackets, and is filled with a buffering gas generating material. By adopting the floating flexible steel composite material bridge anti-collision structure, the defects in the prior art can be overcome; by arranging an anti-collision structure capable of floating on a water surface, adaptability to the change of the water level is realized; moreover, collision force is absorbed and turned in multiple ways, so that the safety of boats and bridges are protected to the maximum extent.
Description
Technical field
The utility model relates to a kind of Protection Structure of Bridge in Collision, especially a kind of floating flexible steel composite material bridge anti-collision structure.
Background technology
In the time of boats and ships through bridge, there is deviation if driven, there will be the friction that scratches of boats and ships and bridge pier, all can cause damage to boats and ships and bridge.In order to reduce this damage, anticollision device, collision-prevention device can be set on bridge pier.But existing bridge anti-collision device exists impact absorptivity low, cannot self adaptation SEA LEVEL VARIATION etc. shortcoming.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of floating flexible steel composite material bridge anti-collision structure; can solve the deficiencies in the prior art; by the anti-collision structure that can swim in the water surface is set; realize the variation of self adaptation water level; and impact is carried out to multi-absorption and break-in, protected to the full extent the safety of boats and ships and bridge.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of floating flexible steel composite material bridge anti-collision structure, structure comprises several steel pipe supports, steel pipe support top is provided with suspension ring, between steel pipe support, links together by wearing around the steel strand on suspension ring; In steel pipe, be filled with energy-absorbing material, steel pipe support arranged outside has crashproof capsule, in crashproof capsule, be filled with padded coaming, crashproof capsule arranged outside has arc rubber layer, the centre of steel pipe support is provided with suspension air bag, in suspension air bag, be filled with air, steel pipe support inner side is provided with impact bag, is contained with buffer gas generating material in impact bag.
As preferably, described energy-absorbing material adopts foamed aluminium.
As preferably, described padded coaming adopts light wood and/or polyurethane foam and/or PVC foam and/or PEI foam and/or PMI foam.
As preferably, described impact bag adopts nylon material.
As preferably, described buffer gas generating material is the mixture of sodium azide and ammonium nitrate.
As preferably, described steel pipe support, suspension ring and steel strand carry out preservative treatment.
The beneficial effect that adopts technique scheme to bring is: the utility model can, according to actual conditions, be adjusted the quantity of joint steel pipe support by steel strand.Foamed aluminium in steel pipe support itself and steel pipe support plays the effect of distortion energy-absorbing in the time there is shock, and outermost arc rubber layer is not only wear-resisting but also can play the outwards effect of guiding of boats and ships, has reduced the dynamics of direct shock.Padded coaming is selected lower-cost material to fill and is formed, and practicality is good.Suspension air bag in the middle of steel pipe support provides enough suspending powers, whole anti-collision structure can be suspended on the water surface, the variation of self adaptation water level.Sodium azide in impact bag and the mixture of ammonium nitrate are can occur to decompose to produce nitrogen being subject to clashing, and impact bag is inflated rapidly, form protective air-bag, further reduce impact force.Steel pipe support, suspension ring and steel strand carry out preservative treatment, have extended application life.
Brief description of the drawings
