Description
Technical field
The utility model relates to aquatic building technical field of safety protection, particularly relates to a kind of anti-collision body for the protection of 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 anti-collision body for the protection of 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 anti-collision body for the protection of bridge bearing platform; comprise two the composite anti-collision blocks being separately positioned on described cushion cap both lateral sides; the shell that described composite anti-collision block comprises fibre reinforced plastics material and the energy-dissipating material of filling in the enclosure; the width of described composite anti-collision block is gradually little to head from the afterbody near described cushion cap, and the afterbody of described composite anti-collision block covers described cushion cap.
As preferably, the shape of described composite anti-collision block is isosceles triangle, the base of described composite anti-collision block is parallel to a lateral edges setting of the transverse direction of described cushion cap, and the width on the base of described composite anti-collision block is greater than a lateral edges of the transverse direction of described cushion cap.
As preferably, the afterbody of described composite anti-collision block is provided with clasp, and described composite anti-collision block is connected with described cushion cap by cable wire, and one end of described cable wire is fixed on described clasp, and one end and described cushion cap are fixed in addition.
As preferably, described cable wire is wrapped with the anticorrosive coat of one deck fibre reinforced plastics material.
As preferably, described energy-dissipating material is 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.
The beneficial effects of the utility model are, this anti-collision body for the protection of bridge bearing platform significantly alleviates the weight of the protector of bridge bearing platform, save material; Composite anti-collision block buffering deformability is strong, at utmost can reduce injury when large-tonnage ships clashes into cushion cap, boats and ships and bridge pier caused, afterbody is gradually little to the width of head, the navigation channel of boats and ships can be changed when ship collision composite anti-collision block, boats and ships and cushion cap are staggered, thus the impact that reduction cushion cap bears; Composite anti-collision block 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, and long-time use can not reduce crashworthiness.
