Description
Technical field
The utility model belongs to the anti-ship of bridge and hits technical field, particularly a kind of novel bridge anti-ship collision device of corrugated steel tube-Combined concrete and anti-vessel-bridge collision.
Background technology
According to statistics, between 1987 ~ 2008 years, the bridge ship that China at least there occurs 21 serious (collapse or close to collapsing) hits accident, about occur 1 every year on average, and accident number is in rising trend.Therefore, when designing navigable waters bridge, must consider that ship hits problem.Otherwise, bridge construction may be caused to occur to destroy and even collapse, cause the social influence of huge economic loss, casualties and passiveness.When the ship demand of hitting is greater than structure impact resistance, the risk necessary Anticollision Measures need being taked to reduce or evade bridge ship hit.At present, the collision avoidance maneuvers of various ways and measure are suggested and are applied in Practical Project.With regard to the Anticollision Measures of physics (passive), have substantially: fender formula structure (comprising: wooden construction, rubber, concrete and steel jacket box etc.), pile formula structure, gravity crash bearer, man-made island, floating fender system etc.Statistics shows, utilization at present comparatively widely safeguard procedures is: steel jacket box, pile anti-collision structure, gravity crash bearer and man-made island.At the anti-collision structure (man-made island and gravity crash bearer) that the countries such as America & Canada mainly select power consumption reliability higher, relatively conservative.This kind of measure often limits by hydrogeological conditions, comparatively large on riverbed impact, and definite meaning can increase the risk that ship hits accident.For steel jacket box Anticollision Measures, adopted in Bisan-Seto bridge by Japanese scholars the earliest, Anticollision Measures due to steel jacket box form has good applicability and economy, also mainly have employed the Anticollision Measures of steel jacket box form in the large bridge that China builds in recent years.
But, for traditional steel jacket box, existing research shows: owing to adopting steel sheet as panel, shock resistance is very limited, under ship collision, (when especially ball head clashes into) steel facing will be pierced prematurely, make the component participating in power consumption very limited, cause the energy efficiency of anti-collision structure entirety very low.On the other hand, the structure that the level of main power consumption in steel jacket box and vertical steel plate are formed, there is isotropic rigidity mostly, vertical and level is little to stiffness difference, under ship hits effect, both unstable failure may occur, the press-bending that progression also may occur destroys, and two kinds of failure mode energy efficiency differences are larger, make steel jacket box energy-dissipating property unstable, its effect in Practical Project cannot be estimated.In addition, conventional steel casing be mostly to be anchored at bridge pier or bridge bearing platform by anchorage element together with, cause bridge and anticollision device, collision-prevention device can not relative movement, no matter boats and ships are fronts or hit device with certain angle, the deformation failure of anticollision device, collision-prevention device all will be relied on completely to the huge kinetic energy of the boats and ships that dissipate, so both uneconomical also dangerous.Meanwhile, owing to adopting steel facing, during inflammable ship collision, steel-steel contact may cause fire or blast.At present, in order to improve the deficiency in conventional steel casing, existing research proposal adopts thin metallic tubd (straight tube) as the dissipative member of anticollision device, collision-prevention device.But the force-displacement curve of this thin-walled straight tube shows sizable fluctuation usually, and especially initial spike power is far longer than average drag, and then reduces the energy efficiency of component.If applied to anti-ship to hit structure, the situation causing because peak value drag is excessive protected structure or boats and ships to destroy prior to anti-collision structure may be there is, the effect of " fuse " can not be played.
Though it is not enough that the Anticollision Measures of existing improvement can overcome above-mentioned part, above-mentioned all deficiencies still can not be made up.
