Description
Technical field
The utility model relates to aquatic building technical field of safety protection, particularly relates to a kind of anticollision device, collision-prevention device for the protection of bridge pier.
Background technology
Along with the development of transportation, over strait, crossing-fiver bridge is constantly built in a large number.And the residing river of this bridge itself, marine site are mostly busy navigation channels, the situations such as its current, great waves, stormy waves are complicated, and bridge inevitably carries the risk of certain ship collision.Under non-situation, boats and ships grazing or when clashing into bridge pier, the crash bearer of bridge, the momentum with the boats and ships of certain speed is very large, according to momentum theorem: mv1-mv2=F Δ t, Δ t are moments, and thus its impact is huge, damages bridge and happens occasionally.When the bridge pier of bridge is by boats and ships grazing continuous action, the huge kinetic energy that boats and ships have is converted to swing, the vibration of bridge pier when touching bridge, and crane span structure is the beam of narrow square-section, its lateral bending and torsional stiffness little, producing crane span structure bending when the runout effect of bridge pier exceedes the bending of crane span structure and torsional stiffness loses hidden, the flexing of result generation lateral bending and torsion, causes crane span structure to rupture caving in (well-known at home and abroad " Jiujiang Bridge 615 vessel bump bridge break accident " is therefore sent out).
At present, in many bridge spanning the seas, bridge pier periphery, navigation channel is provided with anticollision box, or double-walled crash-proof steel bushing box, or flexible energy-absorbing anti-impact structure, reaches the object of protection bridge pier.Wherein, anticollision box or double-walled crash-proof steel bushing box are used for stopping boats and ships, consume the kinetic energy of boats and ships, boats and ships are slowed down, and delay to clash into, and weaken boats and ships to the impact of bridge pier; And flexible energy-absorbing anti-impact structure utilizes steel to enclose the flexible energy system jointly formed with wire rope-rubber combined anti-collision ring, consume boats and ships kinetic energy, boats and ships are slowed down, delay to clash into, weaken boats and ships to the impact of bridge pier.Due to boats and ships grazing or when clashing into the generation of bridge pier situation, Offending Ship kinetic energy is huge, anticollision box, double-walled crash-proof steel bushing box and flexible energy-absorbing anti-impact structure due to the elastic buffer amount of material very limited, small-sized boats and ships can only be prevented, the boats and ships slightly larger for quality or the speed of a ship or plane is slightly large, just well can not absorb the huge kinetic energy of boats and ships, its energy dissipating, anti-collision effect is not good enough, easily break, potential safety hazard still exists, application life is also shorter, need after breaking to change immediately, anticollision box is formed by Plate Welding, it is a huge monster, weigh thousands of tons of, not easily install, perishable after galling, not easily arrange, occupy the shortcomings such as position, navigation channel.Thus, the existing protector to bridge pier needs further improvement.
Utility model content
