Description

A kind of drum-type cruiseway ship hits the bridge protector
Technical field
The present invention relates to navigation channel and bridge security protector, particularly a kind of drum-type cruiseway ship hits the bridge protector.
Background technology
Present several frequently seen bridge anti-collision device
1. fender
What be usually used in the fender mode that the anti-ship of bridge pier hits is rubber fender, and it belongs to direct structure elastic deformation type anticollision device, collision-prevention device.This anticollision device, collision-prevention device is used commonplace at harbour and Wharf Engineering.The rubber fender of countries in the world employing at present mainly contains: compression-type, Puffer-type, shearing-type, rotation and hydraulic pressure type five classes.
Shortcoming: for medium or the high energy collision event is invalid; Initial cost is higher.
2. concrete structure
Concrete structure mode in bridge-collision-avoidance can be divided into two kinds from force-mechanism.The first is prestressed concrete box formula structure, is arranged on around cushion cap, is next endergonic by the conquassation distortion of concrete box, and therefore belonging to direct structure damages deformation type by pressure.By changing the size of concrete box, tank wall thickness, the geometrical arrangements of case inside, very large change can occur in its endergonic ability.The second is the box structure of concrete jacket, is arranged on around cushion cap, and a large amount of rubber parts is installed between cushion cap and bridge pier, when being subject to ship collision, main by the plastic strain of ship fat and the elastic deformation absorption energy of rubber parts, from stressed, should belong to direct structure elastic deformation type.
Shortcoming: the damage to boats and ships is larger; Need maintenance at once after being hit, can not reuse.
3. crash bearer
Crash bearer can be independent of pier shaft to be arranged, operated by rotary motion is in the upstream and downstream position of bridge pier: also can be attached on cushion cap, hit power with cushion cap shared ship.Stake can be adopted timber, concrete pile, steel pipe pile etc.The stake top connects by reinforced concrete structure, jointly resists ship collision.Peripheral general log or the rubber buffer facility installed of steel concrete for the shock of opposing spitkit or drift, avoided rubbing with the box hat hull.
Shortcoming: the degree of injury to boats and ships is larger; Construction cost is more expensive, keep out the shock of boats and ships fully, and scale is general suitable with main pier bearing platform; Only (12m ~ 15m) is applicable under Intermediate Water Depth's condition; Bed scour is larger on its crashworthiness impact.
4. steel work
The steel work anticollision device, collision-prevention device generally is arranged on around cushion cap or bridge pier, mainly to lean on plastic strain and the breakage of steel to come absorbing impact energy, belong to direct structure and damage the deformation type anticollision device, collision-prevention device by pressure, the steel work anticollision device, collision-prevention device can improve its crashworthiness as servicing unit by adopting the anti-collision energy absorption elements such as rubber or wire rope anti-collision ring.
Shortcoming: design is complicated; Cost is high; Be not suitable for SEA LEVEL VARIATION larger navigation channel.
5. cluster stake
Cluster stake guard system belongs to indirect configuration elastic deformation type, is also comparatively common a kind of anticollision device, collision-prevention device.Because ship hits the very large design impact load of generation, cause pilework plastic strain and crushing, as long as ship was just stopped before not bumping against bridge pier, perhaps final impact force is lower than the ability to bear on bridge pier and basis, that is allowed.
Shortcoming: invalid to high energy collision; Construction cost is relatively costly; Only effective in the Intermediate Water Depth; The cost of repairing after great collision accident is relatively high.
6. shell is built the sand cofferdam
Shell is built sand cofferdam shell and generally adopted cylindrical structural, and is inner with concrete or loose Material Filling. can be divided into rigidity thin shell structures and flexible thin shell structure according to the difference of shell.The general structure that adopts similar Double-Wall Steel Boxed Cofferdam of rigidity thin shell structures shell, fill concrete in two walls.Flexible thin shell structure Common Steels sheet pile consists of, also can consist of with the reinforced concrete thin plate stake, the maximum difference of it and rigidity thin shell structures is that housing is not an integral body, but is squeezed into the riverbed substrate and form along the circumference of thin body by plate shaped sheeting pile.
Shortcoming: larger to ship damage, rigid cofferdam particularly, distortion absorbs Impact energy by stem basically; Rehabilitation cost after great collision accident is quite high; Crashworthiness is subjected to the impact of bed scour larger.
7. gravity
The gravity anti-collision facility belongs to direct structure displacement type, and the mode that can utilize frictional resistance or gravity to produce recuperability is come absorbing impact energy, also can simultaneously by hydrodynamic effect, come absorbing impact energy by water movement around anticollision device, collision-prevention device.
Shortcoming: volume is larger; Expenditure of construction is high, the maintenance difficulty.
The requirement of cruiseway bridge-collision-avoidance facilities design
1. volume is little
Cruiseway bridge navigable is generally than little across river bridge spanning the sea navigable, and this has just determined that the bridge-collision-avoidance facility can not take too many ship navigation space.Therefore, when carrying out the design of cruiseway bridge-collision-avoidance, should consider at first whether anti-collision facility takies larger navigation space, on the basis of protection bridge, it is very important dwindling as much as possible bridge-collision-avoidance facility volume.
2. cost is low
With compare across the river bridge spanning the sea, general cruiseway bridge is all little many aspect scale and cost, the millions of up to ten million bridge-collision-avoidance facilities easily for across the river bridge spanning the sea obviously are not suitable for the bridge on general cruiseway.When carrying out cruiseway bridge-collision-avoidance facilities design, the bridge-collision-avoidance facility of " cost performance " high (cost is low, and crashworthiness is good) should be first-selected.
3. little to the damage of boats and ships
Present bridge-collision-avoidance facilities design theory from before the protection bridge be main, be transformed into and should have protected bridge to protect again ship.Meanwhile, this is little with regard to the low tonnage of cost for cruiseway navigation boats and ships, and when bumping with the stronger bridge-collision-avoidance facility of rigidity, ship's damage is very large.
4. regular maintenance and easy to maintenance
For cruiseway navigation characteristics, should design a kind of bridge-collision-avoidance facility that just can continue to use that simply keeps in repair or change after bumping.
Summary of the invention
The purpose of this invention is to provide a kind of drum-type cruiseway ship and hit the bridge protector, this device volume is little, cost is low, little to the boats and ships damage, regular maintenance is easy to maintenance.
