Description
Technical field
The utility model relates to aquatic building technical field of safety protection, particularly relates to a kind of composite anti-collision cofferdam for bridge bearing platform.
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, cushion cap 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 cushion cap.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 cushion cap needs further improvement.
Utility model content
The technical problems to be solved in the utility model is: the problems referred to above existed in order to the protector solving cushion cap in prior art, the utility model provides a kind of composite anti-collision cofferdam for bridge bearing platform and solves the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of composite anti-collision cofferdam for bridge bearing platform, comprise the first bumper ring be set on described cushion cap, the second bumper ring is arranged with outside described first bumper ring, multiple elastic component is provided with between described first bumper ring and the second bumper ring, the first shell that described first bumper ring comprises fibre reinforced plastics material and the first energy-dissipating material be filled in the first shell, the second housing that described second bumper ring comprises fibre reinforced plastics material and the second energy-dissipating material be filled in second housing.
As preferably, described first energy-dissipating material and the second energy-dissipating material are one or more in light wood, polyurethane foam, PVC foam, PEI foam, PMI foam, polyvinyl chloride foam, carbon foam, polyphenyl mortar, rubber tyre, rubber grain, block rubber, polyimide foam or strong core felt.
As preferably, described fibre reinforced plastics adopt fiber and resin to make, described fiber is the one in carbon fiber, glass fiber, basalt fibre, aramid fiber, assorted fibre, and described resin is the one in unsaturated polyester (UP), adjacent benzene resin, vinylite, epoxy resin, inorganic resin or thermoplastic resin material.
As preferably, be linked as a circle between described multiple elastic component by cable wire, the outer wrap of described cable wire has the anticorrosive coat of fibre reinforced plastics material.
As preferably, the inside and outside both sides of corresponding each described elastic component, offer the first groove and the second groove respectively on the outer wall of described first bumper ring and on the inwall of the second bumper ring, described elastic component is fixed between described first bumper ring and the second bumper ring by the first groove and the second groove.
The beneficial effects of the utility model are, this composite anti-collision cofferdam for bridge bearing platform significantly alleviates the weight of the protector of bridge bearing platform, save material; Composite material bumper ring buffering deformability is strong, and at utmost can reduce the injury caused boats and ships and bridge pier when large-tonnage ships clashes into cushion cap, elastic component can reduce the impact force of boats and ships further; Composite material bumper ring corrosion resistance is strong, long service life, and long-time use can not reduce crashworthiness, and structure is simple, and materials are few, conveniently install enforcement.
