Abstract
The utility model provides a novel bridge impact protection device, which comprises an impact energy-dissipating ring and a slide way mechanism, the impact energy-dissipating ring is arranged around a pier, the slide way mechanism comprises a plurality of energy-dissipating guide posts which are fixedly arranged between the impact energy-dissipating ring and the pier and fixedly connected with the impact energy-dissipating ring, the axes of the energy-dissipating guide posts are parallel with the axis of the pier, and each energy-dissipating unit comprises a shell and composite energy-dissipating material filled in the shell. Because the cushioning deformability of the impact energy-dissipating ring is strong, the novel bridge impact protection device can reduce the injuries of a large-tonnage ship and a bridge to the max when the bridge is impacted by the ship; the corrosion resistance of the impact energy-dissipating ring is high, the impact energy-dissipating ring arranged around the pier can float up and down along the surface of water, and the slide way mechanism reduces the resistance applied on the impact energy-dissipating ring as the impact energy-dissipating ring floats up and down, and also plays a certain guiding role, so that the affection of long-time operation in water on the impact energy-dissipating ring is reduced.
Description
Technical field
The utility model relates to aquatic building safety protection technique field, relates in particular to a kind of novel bridge anticollision device, collision-prevention device.
Background technology
Flourish due to economy and communication; the bridge setting up on the navigation channel of navigation is more and more; also increasing; more there is the appearance of the Huo Lian over strait island bridge of overlength; make that original navigation channel diminishes, stenosis; meanwhile how the ship on navigation channel not only also maximizes and does tens thousand of tons from number, so on the newspaper or TV in the whole world, the event that ship clashes into bridge pier happens occasionally and reports.Some little collisions also can be repaired, once it is hardly imaginable that large its consequence of collision occurs, not impaired for make to navigate safety, bridge, people have taked a lot of ways and facility to protect bridge construction thing.
Patent No. CN99236972.X " anti-collide protective device for bridge pier ", this device is that direct holding-solid is used on bridge pier, allow ship impinge upon this device upper with the spring on it by the ship fender effect that rebounded, first impact is still directly born by bridge pier, can more effectively play Anti-bumping protection to bridge pier for small boat, but for tonnage exceedes the large ship of hundred tons, cannot well absorb impact, bridge pier is still kept away unavoidable breakage; 2, because the position of rubber fender is all relatively-stationary, darker for water, tide bulge and fall is waters comparatively frequently, and the quantity that need to increase rubber fender ensures that the impact of ship all only acts on fender, difficulty in installation and layout, has also increased production and maintenance cost.
Its one group of protective device of the number of patent application CN200510029901.4 protective device of bridge pier " navigate clash into " is by the fixed component being arranged in bridge pier surrounding, be arranged on the cushion between fixed component and bridge pier, be fixed on and on fixed component, fill the track of ball bearing and be bonded in, protection skin between lower railway on bridge pier wall forms, first this device ren is to be so directly fixed on bridge pier, the ball being hit is rolled on the protection skin of bridge pier, this is only also perfect condition, in fact hit ball volume very little of protecting skin to make bridge pier surface deformation be difficult to rotate again, bridge pier is also to bear the initial impact of ship, so this installs impact to bridge pier and the buffering of energy, it is also very limited point to lead effect, DeGrain.Its ball is that string rolls on an axle and between two closed slides in addition, the power of at this moment being hit must be on the position, power center (PC) of axle ball and axle just can rotate, obviously this is again a kind of desirable, fictitious state.If in fact stress point is more crooked, whole axle will stuckly cannot be moved in track at all, let alone rotated, and two parallel orbits are fixed on bridge pier simultaneously, if there is foreign matter to fall into track, the possibility that balance is slided is just very little.
Again because bridge pier is very large, and every group of protective device all will install two parallel orbits on bridge pier, and so long track alignment error is wayward, will directly affect the flexibility that ball axle rotates.
At present conventional pile group mode, shell built husky cofferdam mode, man-made island mode etc., is 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.Also have a kind of steel work casing energy-dissipating installation to utilize the damaged energy dissipating of steel plastic strain, " safety device of bridge pier " that for example patent No. is 201010132681.9, but it can only bear single shock conventionally, and after damage, maintenance is more difficult; Hull subject to damage while simultaneously collision; Steel easy-to-rust in water throughout the year in addition, maintenance cost is higher.
