Description
Technical field
The invention belongs to the sea of ocean engineering structure safety protection field, more particularly to a kind of FRP and steel plate combination
Anticollision device, collision-prevention device.
Background technology
With flourishing for transportation, it is more and more that over strait and navigation rivers large bridges are built；With this
Meanwhile, World Ship also further maximizes, high speed.For building afloat works, such as bridge spanning the sea, ocean platform
Deng the own key factor through turning into threat offshore structures life cycle security of ship collision risk.
The vessel bump bridge international data center that the working groups of international maritime association standing meeting PIANO the 19th set up have collected 151
Great vessel bump bridge accident, these accidents occur mainly in Northern European countries, mouth sheet, the U.S., Germany, Britain, France, Belgium and lotus
The countries such as orchid.According to statistics, in 33 years of 1960 to 1993 years, the whole world causes the large bridge of damage because of vessel bump bridge up to 2
Seat, death toll is up to 321 people.Loss maximum is sunlight bridge, the Ta Siman bridges of Australia in the U.S. etc., these bridges
All hit by ship collapse after rebuild.China's vessel bump bridge accident also happens occasionally, and its loss is huge.As Wuhan Yangtze River Bridge since
Nineteen fifty-seven there occurs that more than 70 rise since building up, and wherein major break down of the direct economic loss more than million is more than 10；Yangtze river in nanjing
About 30 vessel bump bridge accidents have occurred so far for bridge bridge construction；White sand a small bay in a river bridge there occurs up to a hundred vessel bump bridge accidents.According to endless
Full statistics, occurs over just China the Changjiang river, the Zhujiang River, the vessel bump bridge accident on the big water system main line in Heilungkiang three and just reaches more than 300.
Recent vessel bump bridge accident has also beaten alarm bell to us.10 points during the June in 2007 of 15 mouthfuls of morning 5, national highway 325 is wide
Vessel bump bridge accident occurs for the Jiujiang Bridge in east.Southern No. 035 ship deviation of osmanthus machine, is strayed into non-navigable, directly impinges 23
Number bridge pier, the direction across bridge impact that the ship is produced is hit much larger than the 400 tons of direction across bridge for designing the bridge pier and allowing, and causes four holes non-
The accident that navigation bridge caves in, while causing the adjacent holes not caved in major injury occur.45 points of left sides during 2007 29 mouthful 12 of days
The right side, in Kunshan City, Jiangsu Province ocean bridge waters, a freighter knocks ocean bridge bridge pier, causes big bridge portion bridge because avoiding ship
Face caves in.
Ship collision accident can cause large effect to social benefit each side, be not limited to huge once occurring
Economic loss and casualties, may also can cause great impact to social industry, traffic, trade, environment and public psychology.
According to statistics, all occur several serious bridge collision once detecteds every year in world wide.Therefore, how to reduce what bridge collision was caused
Loss, it has also become bridge operation management department, shipping lane administrative department and related scientific research worker realistic problem urgently to be resolved hurrily.
Set anticollision device, collision-prevention device effectively to cut down foul power, have indirect configuration measure using more in engineering practice,
Such as cofferdam, rigid man-made island, anticollision pile group, floating block CAS.For example, Normandy bridge of France, the Erie in the U.S.
Promise uses cofferdam method according to river bridge；The Tsing Ma Bridge in Hong Kong, the bridge of spit of fland nine uses artificial island method；FengPu,ShangHai highway bridge, it is yellow
Stone the Changjiang river highway bridge, precipice door highway bridge uses floating energy-dissipating device method；Bridge, Macao Macau-Taipa Bridge, Brazilian Buddhist nun are liberated in Guangzhou
Thyrode is according to river bridge, and Japanese Tokyo Bay highway bridge is using the outer pile of pier and stake fence method.Apparatus above system is by specifically arranging
Guarantee ship collision power is applied not pass on the works of protection, but construction cost is higher.For directly constructing anticollision device, collision-prevention device,
Ship after being hit hits power and passed on offshore structures, and the design philosophy of its core is to cut down ship to hit power, and wherein flexible energy is prevented
Collision device provides an effective thinking, can be achieved to protect ship while protection offshore structures.
Flexible energy-absorbing anti-impact structure should have good except the kinetic energy during the ship collision that can effectively dissipate
Good durability, it is ensured that the harsh corrosivity ring such as erosion, freeze thawing damage, chemical substance invasion and attack in long-term seawater and marine growth
There is good durability, research shows that the bearing capacity of component in marine structure can over time be elapsed and reduced under the bar of border,
Particularly corrosion of steel structure disease is that offshore structures design must emphasis the problem of consider.
Fibre reinforced composites are FRP, are to be composited by stock and high polymer material, with good corrosion resistant
Property, relative to steel construction, also have the advantages that light weight intensity is high, specific stiffness is big, designability stronger than energy absorption ability, in soil
Wood construction, space flight and ocean engineering field are used widely.
