Detailed description of the invention
As shown in Figure 1, land route of the present utility model bridge anti-collision device, comprises the pier anticollision case 2 protecting for bridge pier 1 and the spanning anticollision box 3 protecting for bridge span structure 4.
Pier anticollision case 2 is arranged at the both sides, front and back of bridge pier 1 along vehicle pass-through direction, its width is identical with the width of bridge pier, and the bridge pier that both can adequately protect can be avoided again reducing road passage capability because taking road surface, as shown in Figure 2.
Pier anticollision case 2 is by two coverings 23 before and after two blocks of left and right of upper and lower two the first cover plates 21 of casing, casing the first side plate 22, casing, and the arch honeycomb core 24 that is placed in box house forms, as shown in Figure 3.The first cover plate 21, the first side plate 22, covering 23 can be connected with it by the built-in fitting arranging in arch honeycomb core 24 process, also can be bonding.
The arch honeycomb core 24 of pier anticollision case 2 can adopt stainless steel honeycomb or rustproof aluminum alloy honeycomb, and the plane at two the first side plate 22 places of its core lattice axis direction and upper and lower two the first cover plate 21 place planes and left and right is all parallel.In the time being subject to Vehicular impact, can there is larger distortion in arch honeycomb core 24, thereby absorb most of impact energy.
The first cover plate 21 on pier anticollision case 2, the first side plate 22, covering 23 can adopt superplasticity steel material (for example superplasticity potassium steel) to make, in the time being subject to Vehicular impact, can rely on the plastic strain absorption portion impact energy of self, avoid, because of the fragment that distortion brittle failure produces, passengers inside the car are caused to secondary injury simultaneously.
The protective capacities of pier anticollision case 2 has good designability.By selecting different cellular material types, honeycomb core lattice wall thickness, the honeycomb core lattice length of side or honeycomb core height, can make arch honeycomb core 24 there is different buffer capacities, meet different Bridge Pier demands.
While connection with bridge pier, pier anticollision case 2 can pass by expansion bolt the installing hole of the auricle 25 on covering 23, and then pier anticollision case 2 is installed on bridge pier 1.Bottom Ke Kai mono-sulculus of covering 23, avoids interfering with auricle 25 and the expansion bolt of its lower side anticollision box, as shown in Fig. 4 a.
In addition,, when pier anticollision case 2 is connected with bridge pier 1, also can uses boot band 26 and by expansion bolt, pier anticollision case 2 is connected on bridge pier 1, as shown in Figure 4 b.
The height of the bridge pier 1 that pier anticollision case 2 can protect as required in when application by multiple pier anticollision case 2 layout that vertically superpose, and adopts the pier anticollision case 2 that distortion strength is larger, to improve protection effect in the serious altitude range of Vehicular impact.
Spanning anticollision box 3 is made up of two first baffle plates 33 on two blocks of second side plates 32 of two the second cover plates 31 of the upper and lower both sides of casing, the left and right sides, two sides, front and back and the square honeycomb core 34 that is placed in box house, as shown in Figure 5.The second cover plate 31, the second side plate 32, the first baffle plate 33 can be connected with it by the built-in fitting arranging in square honeycomb core 34 process, also can be bonding.
The square honeycomb core 34 of spanning anticollision box 3 inside can adopt stainless steel honeycomb or rustproof aluminum alloy honeycomb, and its core lattice axis direction and upper and lower two the second cover plate 31 place planes and two of left and right the second side plate 32 place plane parallel, in the time being subject to Vehicular impact, can there is larger distortion in square honeycomb core 34, thereby absorb most of impact energy.
The second cover plate 31 of spanning anticollision box 3, the second side plate 32, the first baffle plate 33 can adopt superplasticity steel material to make, in the time being subject to Vehicular impact, can rely on the plastic strain absorption portion impact energy of self, avoid, because of the fragment that distortion brittle failure produces, passengers inside the car are caused to secondary injury simultaneously.
The protective capacities of spanning anticollision box 3 has good designability, can be by selecting different cellular material types, honeycomb core lattice wall thickness, the honeycomb core lattice length of side and honeycomb core height, make square honeycomb core 34 there is different buffer capacities, meet different bridge span structure protection requirements.
Spanning anticollision box 3 can pass through expansion bolt, through the auricle on the first baffle plate 34 of rear side, anticollision box 3 is arranged on bridge span structure 4, and the bottom surface of casing flushes with the bottom surface of bridge span structure 4, both the bridge structure 4 that collapses was protected comprehensively, can avoid again affecting road passage capability because reducing bridge opening height.
It is multiple that spanning anticollision box 3 can be close to layout in the horizontal direction, thereby strengthen protective capacities.
It should be noted that, pier anticollision case 2, spanning anticollision box 3, have good natural environment applicability, and in use procedure, without special maintenance demand, maintenance cost is low, easy accessibility.
Certainly,, in order to have more practicality, the square honeycomb core 34 in arch honeycomb core 24, spanning anticollision box 3 in pier anticollision case 2, also can substitute with foam metal.
The content not being described in detail in the utility model manual belongs to those skilled in the art's known technology.
