Description
Technical field
The present invention relates to a kind of anti-floating materials of bridge structure, ship collision surface unit, more particularly, to a kind of multistage slow
Rush energy-dissipating type anticollision corrosion-resisting steel buoyancy tank.
Background technique
Risk is hit for reduction bridge ship and takes engineering measure.When ship impact force is close or much larger than bridge pier carrying
When ability, the anticollision protection system that setting is attached to bridge pier can protect bridge pier from impact damage and avoid thus caused bridge
Beam superstructure is collapsed.And for the requirement for meeting bridge durability, even if when ship impact force is less than bridge pier bearing capacity,
Also the anti-ship that corresponding scale can be set hits facility to prevent from being hit such as bridge pier concrete by ship and fall and influence bridge pier durability
It destroys.
Surface unit compared with stationary installation, it is obvious, tidal range is big to SEA LEVEL VARIATION situations such as adaptive faculty it is stronger, while work
Journey cost is relatively low.Steel mechanics performance is stablized, and related-art process is the most mature, therefore steel class surface unit obtains in recent years
To relatively broad application, but also expose some problems:
It is during normal service first, surface unit is constantly in contact and rubs with Concrete Bridge Structures surface, causes
There are the diseases such as Surface layer's concrete peels off, reinforcing bar exposes in structure.
Aspect is repaired after hitting.After device is collided by varying strength, carry out the tedious time-consuming of maintenance work.Especially for
Small intensity hits lower generation local damage, causes device dense water to fail, after will removing it from anticollision device, collision-prevention device, in factory
Carry out large repairs (or remanufacture new monomer), confirms through watertight test, and after reaching anticorrosion of steel structure design requirement, then carries out
Installation is fixed.After device is collided by the high intensity of large ship, cause the large area of device impaired, water body pours into cabinet,
If leading to device submerged with bridge structure without effectively connecting, loss is serious.
Anti-corrosion maintenance aspect.As steel class anti-collision structure, due to spitkit collision or the collision of relatively large marine low speed or
Because of other accidentalia, local little damage is caused, moist external environment induces the breakage big face of anti-corrosion coat of paint nearby in addition
Accumulate obscission frequent occurrence, therefore device anti-corrosion in design service life maintains the problem of becoming another urgent need to resolve.
Chinese patent CN102535329A discloses a kind of cylindrical composite bridge anticollision device, by straight tube shape and curved cylinder
Shape anti-collision unit assembly.Anti-collision unit is made of cylinder and the intracorporal packing material body of cylinder, and nearly bridge structure side is equipped with movement
Device.The patent structure is simple, when in face of uncertain impact load, there are crashworthiness defence line is single, grading performance is indefinite etc.

After buoyancy tank is by the high-intensitive collision of large ship, each anticollision module is successively destroyed, and when reparation, completes anticollision segment level
Maintenance or replacement.In addition, the anti-corrosion maintenance problem as steel class anti-collision structure is particularly significant, how to realize steel buoyancy tank normal
Non-maintaining problem values during military service or after slight shock, scraping collision must be furtherd investigate.
Compared with prior art, the invention has the following advantages that
One, multistage crashworthiness is set up defences, and it is clear that module divides, and the performance indicator and performance rate for being easy to establish steel buoyancy tank divide.Include:
The first order, which buffer-can be retracted, is in rolling contact module, second level energy-absorbing-sliding contact module, third level energy consumption-corrosion-resisting steel case mould
Block.
Two, replaceable, easy to maintenance, engineering value and economic benefit are prominent.Small to hit light maintenance: maintenance or the replacement first order are slow
It rush-can be retracted and be in rolling contact module, second level energy-absorbing-sliding contact module.Overhaul is hit greatly: maintenance or replacement third level energy consumption-
Corrosion-resisting steel tank module.
Three, self-buoyancy still has self-buoyancy by force, after serious damage.Different subfunction areas are arranged in incorporation engineering experience
Domain module.Existing hull structural design and typical ship collision accident case show that above water anticollision device, collision-prevention device is main stress area,
Underwater portion takes second place.The present invention, which is from bottom to top divided into, hits rear defence sinker module, anticollision submodule.Hit the guarantee of rear defence sinker module
Device breakage enters water body and does not sink, and inside sets longitudinal stiffener item and light-weight high-polymer material, is guaranteeing single unit system tool
While standby very strong self-buoyancy, has good buffering energy-consumption ability.Anticollision submodule is mainly to be hit region, built-in rubber
Class material, deformability is strong, and buffering effect is significant.
Four, buffering effect is obvious, and energy dissipation capacity is prominent.It is strong to roll over abdomen formula energy-absorbing pedestal deformability, under low-intensity is hit, folding
Abdomen formula energy-absorbing pedestal deforms first, has certain buffering effect of energy dissipation, other modules do not deform or deform unobvious.
Under moderate strength is hit, folding abdomen formula energy-absorbing pedestal deformation is obvious, is more than after the specified distance that extends, collaboration rubber fender generates good
Buffering effect, slight deformation does not occur or occurs for main body steel case at this time.Under high intensity is hit, the first order, second level crashworthiness are anti-
After line successively works, further, main body steel case deforms, the double-deck steel construction cooperation built-in rubber class material or macromolecule material
Material, so that apparatus main body energy dissipation capacity is prominent.
Five, corrosion resistance is extremely strong, and clad steel plate makes during device normal service or slight hit, is non-maintaining after scraping collision.
It solves spitkit collision or the collision of relatively large marine low speed or because of other accidentalia, local little damage is caused to induce
The problem of neighbouring anti-corrosion coat of paint large area falls off.
