The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.As shown in Figure 1, embodiment for Y type variable cross-section anticollision device of pier, be respectively in around two bridge piers 11 about be provided with the guidance sets 13 that guide pillars and bushes is formed in the middle of two casings 17,18, two casings 17,18 close up at divisional plane DD about during low water stage, in the guidance set 13 income left and right sides casings in the middle of this moment.Two casings 17,18 separate at divisional plane DD about during high water level, and middle guidance set 13 as shown in Figure 7.Left and right sides casing 17,18 following water-level liftings of anticollision device, collision-prevention device of the present invention and divide to merge along protected bridge pier/king-post 11 external surfaces at divisional plane DD slide, and are enclosed in all the time around protected bridge pier/king-post 11.
From accompanying drawing 1-7 find out anticollision device, collision-prevention device body of the present invention by 1,2,3,4,5,6 and braced structures 7,8 form, two independent sectors 17,18 about described many cabins floating casing anticollision device, collision-prevention device is divided into, divisional plane is at the DD place.Left and right casing respectively contains three splits 1,2,3 and 4,5,6 (showing as Fig. 3) again, be formed by connecting with bolt, fuse, put around bridge pier 11 at the CC face, left and right sides two large divisions 17,18 can move freely along guidance set 13 in the horizontal direction, thereby satisfies the crashproof requirement of variable cross-section bridge pier.The anticollision device, collision-prevention device body interior is seal hatch, the lattice supporting framework of a plurality of slab and girders.
The anticollision device, collision-prevention device installed inside has a plurality of isolated components, and they are anti-wear component 12 (seeing Fig. 6,7), anti-attrition element 9 (seeing Fig. 8,9,10,11) and buffering energy-absorbing damping element 16 (seeing Figure 10,11), and they make the anticollision device, collision-prevention device can be along the bridge pier free floating.Isolated component also can add and is located on the inboard link 7,8, and it is relative with the downstream face of upstream that its upstream face 10 with bridge pier/king-post downstream is contacted.
Floating variable cross-section slip anticollision device, collision-prevention device of the present invention has following advantage:
(1) with variable cross-section bridge pier external surface as guide slide, realize the protection of variable cross-section pier anticollision;
(2) many places are equipped with the anti-attrition element or/and anti-wear component or/and the buffering energy-absorbing damping element directly contacts with the bridge pier surface, has reduced the wearing and tearing with the bridge pier surface;
(3) main-body structure is firm, is made up of several splits, and the ability of the little energy impact of enough opposing pilositys is arranged, and long service life is convenient to maintenance and repair.
It can be installed in around the bridge pier/king-post that is arranged in the navigation channel, prevents that vessel or other floating thing from directly clashing into bridge pier/king-post, guarantees that bridge pier/king-post is without prejudice.
Described left and right sides two large divisions 17,18 can move in the horizontal direction freely, is meant after SEA LEVEL VARIATION, and under different water levels, part can be slided along protected bridge pier external surface (10 or 14) about anticollision device, collision-prevention device, and the anticollision device, collision-prevention device action is as follows:
1) in the upstream of anticollision device, collision-prevention device; because hydrodynamic effect; right half (upstream portion) 18 of two major parts of anticollision device, collision-prevention device and isolated component 9 thereof are or/and 12 or/and 16 contact (showing as Fig. 1) with the external surface 14 of variable cross-section bridge pier all the time; the external surface 14 of the variable cross-section bridge pier of this moment is equivalent to a guide slide; when level and vertical force reach new equilibrium state; right half (upstream portion) is just along the external surface 14 of variable cross-section bridge pier; be subjected to displacement in level and vertical direction; casing 18 is enclosed in around bridge pier/king-post 11 all the time, satisfies the Anti-bumping protection of variable cross-section bridge pier/king-post 11.
2) in the downstream of anticollision device, collision-prevention device; the left half (downstream part) 17 of two major parts of anticollision device, collision-prevention device; can be because hydrodynamic effect; and float external surface from the variable cross-section bridge pier; at this moment; isolated component 9 on the left half (downstream part) 17 is or/and 12 or/and 16 contact with the external surface 10 of variable cross-section bridge pier all the time; the external surface 10 of the variable cross-section bridge pier of this moment is equivalent to a guide slide; when level and vertical force reach new equilibrium state; left half (downstream part) 17 is just along the external surface 10 of variable cross-section bridge pier; be subjected to displacement in level and vertical direction; casing 17 is enclosed in around bridge pier/king-post 11 all the time, has satisfied the Anti-bumping protection of variable cross-section bridge pier/king-post 11.
Accompanying drawing the 8, the 9th adopts the embodiment of different isolated components, accompanying drawing 10,11 to show the partial structurtes signal of isolated component.
