Abstract
The utility model relates to a protector for bridge piers and anti-collision piers, wherein a protective framework with a truss structure of unchanged geometry is formed by the mutual connection of a plurality of rod members. The protective framework is erected at the periphery of a bridge pier or an anti-collision pier and the outer side of the framework is equipped with an anti-collision pad. The inner periphery of the framework is equipped with a buffer energy absorber. An air reservoir is arranged inside the framework. Energy dissipating waterpower cylinders or oil cylinders are connected with a hydraulic station via a pipeline so as to form a protective system. Then the energy dissipating cylinders are uniformly distributed at the periphery of the bridge pier or the anti-collision pier so as to establish an energy dissipating and safety protection system. In the same way, a protective hurdle for bridge non-waterway priers is a protective framework with a truss structure of unchanged geometry formed by the mutual connection of a plurality of rod members. An air reservoir is arranged inside the framework and a gravity anchor is hung on the framework. Then the protective hurdle is formed by the successive connection of the frameworks. Compared with the prior art, the material and the cost are greatly saved and the impact resistance ability of bridge piers is improved by utilizing the protector. Meanwhile, the kinetic energy of accident-making ships can be effectively absorbed so as to realize the safety protection effect on bridge piers.
Description
Technical field
The utility model relates to the resist technology field of bridge, relates in particular to the bridge pier of bridge and the protector of crash bearer.
Background technology
Along with the continuous development of transportation, over strait in a large number, stride Jiang Qiaoliang and constantly build.And the residing river of this bridge itself, marine site mostly are busy navigation channels, situation complexity such as its current, great waves, stormy waves, and bridge is being born the risk of certain ship collision inevitably.Under non-situation, when bridge pier, the crash bearer of boats and ships grazing or bump bridge, the momentum of boats and ships with certain speed is very big, and according to momentum theorem: mv1-mv2=F Δ t, Δ t is moment, thereby its impact is huge, damages bridge and happens occasionally.When the bridge pier of bridge during by boats and ships grazing continuous action, the huge kinetic energy that boats and ships had is converted to swing, the vibration of bridge pier when the touching bridge, and crane span structure is the beam of narrow square-section, its lateral bending and torsional stiffness are little, when surpassing the bending of crane span structure and torsional stiffness, the runout effect of bridge pier produces crane span structure bending unstability, generation lateral bending and the flexing reversed as a result cause crane span structure fracture cave in (therefore " Jiujiang Bridge 615 ships hit the disconnected accident of bridge " well-known at home and abroad sent out).
At present, in many bridge spanning the seas, navigation channel bridge pier outer periphery is equipped with anticollision box, or the double-walled crash-proof steel bushing box, or flexible energy-absorbing anti-impact structure, reaches the purpose 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, and boats and ships are slowed down, and delay bump, weaken the impact of boats and ships to bridge pier; And flexible energy-absorbing anti-impact structure is to utilize steel to enclose and the common flexible energy system that forms of wire rope-rubber combined anti-collision ring, consumes boats and ships kinetic energy, and boats and ships are slowed down, and delays bump, weakens the impact of boats and ships to bridge pier.Because when boats and ships grazing or bump bridge pier situation take place, Offending Ship kinetic energy is huge, anticollision box, double-walled crash-proof steel bushing box and flexible energy-absorbing anti-impact structure are because the elastic buffer amount of material is very limited, can only prevent small-sized boats and ships,, just can not well absorb the huge kinetic energy of boats and ships for quality bigger slightly or the big slightly boats and ships of the speed of a ship or plane, its energy dissipating, crashproof effect is not good enough, break easily, potential safety hazard still exists, and application life is also shorter, need after breaking to change immediately, anticollision box is welded by steel plate, is a huge monster, and thousands of tons of weighs, be difficult for installing, the galling back is perishable, is difficult for arranging, occupies shortcomings such as position, navigation channel.Thereby existing protector to bridge pier needs further improvement.
At present, in the bridge of sea, many rivers, navigation channel bridge pier external water area is provided with crash bearer, stops or guide Offending Ship entering bridge pier zone, navigation channel, because Offending Ship kinetic energy, momentum are huge, in case the bump crash bearer is rigid collision fully, ship is ruined the people die, crash bearer bursts apart, and causes the maritime affairs disaster.Thereby existing crash bearer needs further improvement.
Number of patent application 201020142239.X " safety device of bridge pier ", have following problem in this scheme: 1, the steel bushing case is that steel plate is welded, in seawater anticorrosion decades, on a century do not accomplish, though the current cathodic protection device is arranged, in case grazing, steel plate corrosion still quickens; 2, the steel bushing casing is long-pending big, and the big manufacturing of weight is not easy, and installation difficulty is big; 3, the support hydraulic cylinder is distributed in outside the steel bushing case external surface, and when the ship collision bridge pier, the support hydraulic cylinder quantity that can link simultaneously is few; 4, the support hydraulic cylinder piston rod is overhanging, and the stability when being impacted remains to be tested; 5, the hydraulic system maintenance maintenance acquires a certain degree of difficulty.
At present; in many bridge spanning the seas and rivers bridge; what adopt is a kind of crying " flexible and floating type collision avoidance system "; promptly throw in one group of string floating drum together at the place, marine site of 100 meters on the non-navigation bridge pier of distance, per 3 floating drums are fixed with a gravity anchor, in case there is ship to hit; hull is forward in tow for floating drum; consume most of kinetic energy, speed approaches 0, protection hull and bridge pier when guaranteeing substantially that hull arrives near the non-navigation bridge pier.Its weak point is: 1, floating drum in tow the Offending Ship hull consume kinetic energy, gravity anchor tens of rice of walking about, nearly hundred meters, only be suitable for energy level and be 1,000,000 joules Offending Ship, promptly 300 tonnes Offending Ship freely drifts about.For example: about at 5 o'clock in afternoon on the 16th November in 2009, S.Korean nationality boats and ships " mark's wheel " (weigh 2080 tons bulk freighter, speed is 10 kms per hour if drift about, its kinetic energy is 7,730,000 joules of energy dissipatings much larger than the floating collision avoidance system), be docked in the Jin Tang anchorage, the sea was a billow at that time, the high 4-5 rice of wave, estimation is exactly that the stormy waves reason causes dragging of anchor, and breaks off relations the non-navigation bridge of the golden pool bridge pier of having swiped from the anchorage.2, might slip through the net, Offending Ship passes one group of string floating drum together, enters near the non-navigation bridge pier.Thereby the protector of existing non-navigation bridge pier needs further improvement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bridge pier of bridge and the protector of crash bearer at the present situation of prior art; it can effectively absorb the kinetic energy of Offending Ship; cut down momentum; delay collision time; can significantly strengthen the impact resistance of bridge pier and crash bearer; play the protective effect to bridge pier and crash bearer, and install durable in usely, maintaining is convenient.
