Description
Technical field
The present invention relates to a kind of bridge or dock crash-proof device; Especially a kind of cost that utilizes composite material to make is low, elasticity is big, corrosion resistant anticollision device, collision-prevention device, specifically a kind of bridge pier that is applicable to all kinds of bridges and harbour, (ocean) waterborne building like production platform etc. in order to alleviate the tubular bridge anti-collision device of composite material of boats and ships (floating ice) impact disaster.
Background technology
Ship hits the bridge accident and is taking place constantly all over the world always, and the frequency that ship hits the bridge accident is higher more than our imagination.It is surprising hitting casualties, property loss and the environmental disruption that the bridge accident caused by ship.A lot of ships hit the bridge accident and gently then lose tens thousand of units, and heavy then casualties, loss are in millions of, tens million of even multi-million dollar, and a large amount of indirect losses is difficult to calculating especially.
Many facts show that the generation of bridge accident mainly is because therefore the destruction of bridge substructure, need to improve the crashworthiness of bridge pier, specifically can be divided into two aspects, promptly initiatively anti-hitting and passive anti-hitting.Initiatively anti-hitting is the impact resistant capability that improves bridge pier self through bridge construction design, often need be with the bridge pier design very large incomparable, economy and beautiful appearance has neither also influenced the navigation ability in navigation channel; Passive anti-hitting is through the impact resistant capability that anticollision protection system improves bridge pier being set, because its flexibility is bigger, can adopting kinds of schemes comprehensively to compare according to actual conditions, is to use more crashproof means.
Use through years of researches, occurred polytype pier anticollision facility both at home and abroad, the design but its basic principle is based on energy absorption, momentum buffering, every kind of anti-collision facility all has its characteristics and service condition.But pile group mode, shell at present commonly used are built husky cofferdam mode, man-made island mode etc., are applicable to generally that water is shallow, geological condition occasion preferably, though put things right once and for all, can influence the navigation channel, and usually because cost is too high or condition does not possess and abandon.And steel work casing energy-dissipating installation utilizes the damaged energy dissipating of steel plastic strain, but it bears the single bump usually, and maintenance is difficult after the damage; Hull subject to damage when colliding simultaneously; Steel easy-to-rust in water throughout the year in addition, maintenance cost is higher, and in view of many drawbacks that anti-collision facility at present commonly used exists, the crashworthiness performance that this patent is planned fiber-reinforced composite materials structures is incorporated in the bridge-collision-avoidance field.
Summary of the invention
Crashproof weak effect, the cost that the objective of the invention is to exist to existing bridge anti-collision device be high, repair problems such as difficulty is big, provides that a kind of cost is low, elasticity is big, corrosion-resistant and can fully absorb Impact energy, delay collision time, can bear the tubular bridge anti-collision device of composite material of multiple impact.
