Description
Technical field
The invention belongs to the technical field of bridge security, particularly a kind of protector of bridge pier.
Background technology
Along with being showing improvement or progress day by day of Science & Society, the size of ship and tonnage, and the density of gap bridge ship has had all than ever and significantly increases, the speed of ship is also significantly improving, and the accident of ship collision with piers occurs again and again.Therefore, about safety and the design of bridge pier, more and more come into one's own.
Have multiple pier anticollision facility in prior art, commonplace is anticollision energy eliminating circle, and anticollision energy eliminating circle is generally bolted by several energy dissipating unit and forms, and forms an annular, protects bridge pier.When hull and bridge pier occur to clash into, first bump against with anticollision energy eliminating circle, anticollision energy eliminating circle plays a cushioning effect to hull, protects bridge pier and hull.
But for some ships, particularly large vessel, fore is protruding forward, the even degree of convexity had is fairly obvious, for such ship, common anticollision energy eliminating circle 2 is adopted not have effect, because when hull 3 does not also touch anticollision energy eliminating circle 2, fore bossing 5 has struck on bridge pier 1, as shown in Figure 1.
Summary of the invention
The technical problem to be solved in the present invention is: the ship for fore with bulge-structure, provides a kind of anticollision energy eliminating circle protecting bridge pier,
Be specially a kind of domatic anticollision energy eliminating circle, it is the anticollision energy eliminating circle of the ring-type connected into by several energy dissipating unit, be looped around the surrounding of bridge pier, each energy dissipating unit structurally comprises base, support portion and slope layer, the energy dissipating unit that three surrounds is hollow right-angled triangle in bridge pier cross section axially, between support portion and slope layer, be provided with the reinforcing rib being parallel to base
By connector between several energy dissipating unit, be connected successively, form the anticollision energy eliminating circle of a ring-type, and connector be positioned on the external surface of slope layer,
Base, support portion and slope layer are integrated, and the volume of this energy dissipating unit is much bigger compared with solid energy dissipating unit of the prior art; From bridge pier cross section axially, the width of the base of this energy dissipating unit also wants much wide compared with solid energy dissipating unit of the prior art, in order to make on this energy dissipating unit bubbles through the water column, present invention employs hollow structure, replace the solid construction of energy dissipating unit of the prior art, simultaneously in order to ensure holding capacity during energy dissipating unit impact resistance, the present invention is between support portion and slope layer, the reinforcing rib being parallel to base is set, reinforcing rib is bolted, and is fixed between support portion and slope layer.
The thickness of support portion and slope layer is equal, be 1/2nd of base thickness, because first base contacts with river surface, the volume of increase base is the immersion volume in order to make energy dissipating unit, all concentrate on (as shown in Figure 3) on base, doing so avoids river to flood to slope layer and support portion
Due to buoyancy, above base portion is bubbled through the water column, and slope layer and support portion are held up, base is basic parallel with the water surface, this energy dissipating unit is at bridge pier cross section structure axially, roughly corresponding with the bulge-structure of hull front end in accompanying drawing 1 or accompanying drawing 4, now, before ship strikes bridge pier, the bossing of hull front end, can stop by the slope layer on energy dissipating unit, to hull produce cushioning effect, avoid the shock of hull front end to bridge pier, as shown in Figure 4;
As preferably: slope layer is 45 ° relative to the gradient of the plane of described base, because base plane is parallel with the water surface substantially, so the layer gradient with respect to the horizontal plane in slope is also almost 45 °,
As preferably: connector comprises, and is fixed on clasp and a connecting rod of the junction of adjacent two energy dissipating unit, and the two ends of connecting rod are connected to a fixed with two clasps respectively;
As preferably: connector comprises, and is fixed on clasp and a chain of the junction of adjacent two energy dissipating unit, and the two ends of chain are connected to a fixed with two clasps respectively, and described chain is in tension.

Detailed description of the invention
The invention provides a kind of domatic anticollision energy eliminating circle, it is the anticollision energy eliminating circle of the ring-type connected into by several energy dissipating unit 21, be looped around the surrounding (as shown in Figure 2) of bridge pier 1, each energy dissipating unit 21 structurally comprises base 22, support portion 23 and slope layer 24, the energy dissipating unit 21 that three surrounds, be hollow right-angled triangle in bridge pier 1 cross section axially, slope layer 24 is 45 ° relative to the gradient of the plane 221 of base 22, between support portion 23 and slope layer 24, be provided with the reinforcing rib 25 being parallel to base 22
By connector 26 between several energy dissipating unit 21, be connected successively, form the anticollision energy eliminating circle of a ring-type, and connector 26 be positioned on the external surface 27 of slope layer 24; Connector 26 comprises, be fixed on the clasp 30 of the junction 29 of adjacent two energy dissipating unit 21 and a connecting rod 31 or chain 32, the two ends of connecting rod 31 or chain 32 are connected to a fixed (if adopt chain, chain 32 is in tension) respectively with two clasps 30
Base 22, support portion 23 and slope layer 24 are integrated, and the volume of this energy dissipating unit 21 is much bigger compared with solid energy dissipating unit of the prior art; From bridge pier 1 cross section axially, the width of the base 22 of this energy dissipating unit 21 also wants much wide compared with solid energy dissipating unit of the prior art, bubble through the water column on 4 in order to this energy dissipating unit 21 can be made, present invention employs hollow structure, replace the solid construction of energy dissipating unit of the prior art, simultaneously in order to ensure holding capacity during energy dissipating unit impact resistance, the present invention is between support portion 23 and slope layer 24, the reinforcing rib 25 being parallel to base is set, reinforcing rib 25 is connected by bolt 28, is fixed between support portion 23 and slope layer 24.
The thickness of support portion 23 and slope layer 24 is equal, be 1/2nd of base 22 thickness, because first base 22 contacts with the water surface 4, the volume of increase base 22 is the immersion volumes in order to make energy dissipating unit 21, all concentrate on (as shown in Figure 3) on base 22, doing so avoids river to flood to slope layer 23 and support portion 24
Due to buoyancy, base 22 part is bubbled through the water column above 4, and slope layer 23 and support portion 24 are held up, base 22 is basic parallel with the water surface 4, this energy dissipating unit 21 is at bridge pier 1 cross section structure axially, roughly corresponding with the bulge-structure of hull front end in accompanying drawing 1 or accompanying drawing 4, now, before ship strikes bridge pier, the bossing of hull front end, can stop by the slope layer 24 on energy dissipating unit 21, to hull produce cushioning effect, avoid the shock of hull front end to bridge pier, as shown in Figure 4.
