Description
Technical field
The present invention relates to bridge impacting technology field, be that a kind of easy installation, energy-absorbing are good, the bridge collision prevention system of good toughness specifically, can be used for bridge-collision-avoidance.
Background technology
According to the introduction of interrelated data document, vessel bump bridge accident is constantly occurring all over the world always, the frequency of vessel bump bridge accident more than we imagine higher.The casualties caused by vessel bump bridge accident, property loss and environmental disruption are surprising.A lot of vessel bump bridge accident gently then loses tens thousand of unit, heavy then casualties, loses in millions of, tens million of even multi-million dollar, and a large amount of indirect losses is difficult to calculate especially.Along with the fast development of transportation, the large bridge quantity in leap that China builds in the recent period navigation rivers, port district and straits progressively increases, and on navigation channel ships quantity also constantly increase and ship type be tending towards maximize, make the contradiction between bridge and current boats and ships increasingly outstanding, therefore the accident of ship collision bridge pier also constantly increases.As Wuhan Yangtze River Bridge, built up to from 1975 and there occurs altogether in the of 70 on December 18th, 1999, the major break down that wherein direct economic loss is up to a million rises more than l0, and the vessel bump bridge event occurred on China the Changjiang river, the Zhujiang River, the large water system main line in Heilungkiang three more reach more than 300 rise above.The anti-ship of bridge problem of hitting also obtains the great attention about the department such as shipping management, planning and designing just gradually.
When the bridge pier structure designed is not enough to the impact force of bearing boats and ships, as strengthening bridge pier anti-collision ability, often cost a lot of money, even unlikely enforcement.Now anti-collision facility will be set separately.For this reason, external scholar has taken the lead in having carried out relevant research, proposes bridge collision theory, and have devised some bridge protective equipments.
At present conventional pile group mode, shell build husky cofferdam mode, man-made island mode etc., are generally applicable to that water is shallow, the good occasion of geological condition, although put things right once and for all, can affect navigation channel, and usually because cost is too high or condition does not possess and abandons.Steel work casing energy-dissipating installation utilizes the damaged energy dissipating of steel plastic strain, but utilize the deformation energy of steel box structure to consume the impact kinetic energy of boats and ships, but both rigidity are all very large, the maximal impact occurred in impact moment passes to bridge pier by steel case immediately, and distortion, energy dissipating to be produced under bridge pier supports state, it bears single impact usually, keeps in repair more difficult after damage; Hull subject to damage during collision simultaneously.
Summary of the invention
The object of the invention is for prior art Problems existing, provide that a kind of easy installation, energy-absorbing are good, the fender system of a kind of soft or hard alternating laminated structure of good toughness.
The technical solution used in the present invention is: a kind of fender system of soft or hard alternating laminated structure, comprise anticollision device, collision-prevention device and expansion bolt, described anticollision device, collision-prevention device is connected with abutment or bridge post by expansion bolt, abutment and bridge post leave preformed hole, anticollision device, collision-prevention device leaves installing hole and bolt hole, the profile of anticollision device, collision-prevention device is rectangle, semicircle or quadrant shape, anticollision device, collision-prevention device is made up of rigid layer and flexible layer, the quantity of described rigid layer and flexible layer is multilayer, rigid layer and flexible layer are alternately arranged mutually, described rigid layer is steel plate, metal sheet, composite panel, steel work or composite structure, described flexible layer is General Purpose Rubber, rubber composite, polyurethane elastomer or foamed plastics.
As preferably, when described anticollision device, collision-prevention device profile is rectangle, radian section is arranged at anticollision device, collision-prevention device two ends.
Beneficial effect: the present invention, by adding a kind of fender system of soft or hard alternating laminated structure on bridge, can improve the crashproof ability of bridge, all right weight reduction, corrosion-resistant.The present invention is applicable to the fields such as bridge-collision-avoidance.
