Description
Technical field
The ship that the utility model relates to bridge hits resist technology field, and the ship that relates in particular to the crane span structure of the bridge pier of bridge and the crash bearer of bridge and bridge hits protector.
Background technology
Along with the development of transportation, in a large number over strait, constantly build across Jiang Qiaoliang.And the residing river of this bridge itself, marine site are mostly busy navigation channels, the situation complexity such as its current, great waves, stormy waves, bridge is inevitably being born the risk of certain ship collision.Under non-situation, boats and ships grazing or while clashing into the crane span structure of bridge pier, bridge of bridge, the momentum of boats and ships with certain speed is very large, according to momentum theorem: mv1-mv2=F Δ t, Δ t is moment, thereby its impact is huge, damages bridge and happens occasionally.
At present, the form that ship hits the anticollision device, collision-prevention device of bridge can be divided into: 1. momentum transition form; 2. momentum transition form after first kinetic energy conversion; 3. kinetic energy transition form; 4. the kinetic energy correction form of changing and navigate.
Protection effect the latter that ship hits bridge is better than the former, and safety the latter is better than the former, and economy the latter is better than the former, and technology content the latter is higher than the former.
The crash-proof steel bushing box of conventional momentum transition form is the kinetic energy that the distortion of application crash-proof steel bushing box consumes ship, the collision of application crash-proof steel bushing box and ship consumes the impact energy (Carnot's theorem of collision) of ship, / 3rd of a quality that is ship according to the quality of " highway bridge ship hits design guidelines " crash-proof steel bushing box of the U.S. in 2009,8% of the about bridge total cost of its cost.The anti-ship of application crash-proof steel bushing box hits protector and is confined to: 1. crash-proof steel bushing box is at sea installed must huge ocean hanging device, there is no at present extra large loop wheel machines more than five kilotons; 2. due to navigation channel restriction, the side width of crash-proof steel bushing box is generally 2 meters of left and right.Due to the restriction of above-mentioned condition, crash-proof steel bushing box is only applicable to the protection that ten thousand tons of ships below wheel hit bridge.
In recent years adopt " bridge ship hits flexible protective device " of momentum, kinetic energy and momentum transition form, it comprises that outer steel encloses, flexible protection circle and interior steel ring, round pier cap, a lot of flexible protection circles between interior buoyancy tank and outer buoyancy tank, are filled, described outer steel encloses and needs nominal mass, with foul, consume part boats and ships kinetic energy, i.e. momentum conversion; Under the effect that steel encloses outside, flexible protection circle rolls, moves between interior outer rim, and work done, has consumed again a part of boats and ships kinetic energy, i.e. kinetic energy conversion; The active force enclosing when outer steel surmounts the tensile strength of pulling of flexible protection circle, and anti-collision ring is ground flat, and outer steel encloses and knocks interior steel ring, knocks bridge pier; When ship side-play amount is being less than 1/4 pier cap width, in this side-play amount, steel encloses under the effect on inclined-plane outside, after ship collision, take away 40-60% kinetic energy, flexible protective device has crashproof and homing capability, when ship side-play amount is greater than 1/4 pier cap width, because pressing outer steel, encloses ship extruding anti-collision ring, anti-collision ring deflection is limited, rolling and displacement are limited, and work done is limited, so be easy to exceed the tensile strength of pulling of anti-collision ring material, anti-collision ring is by tearing, grind flat, outer steel enclose enclose with interior steel together with secondary impact bridge pier, i.e. momentum conversion; The huge inertia force of ship will produce serious threat to bridge pier.Therefore the crashproof ability of flexible protective device be only suitable for the opening the navigation or air flight bridge ship of ten thousand tons of ships hits protector.The crashproof ability of wish expansion flexible protective device must be changed to strengthening kinetic energy the ability of this ring, strengthens the buffer capacity of anti-ship collision device.
