Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Depend on Figures 1 to 4 As shown, an embodiment of the utility model provides an anti-collision energy dissipation device for a bridge pier, comprising two groups of protection components 1 installed on the peripheral side of the bridge pier, the protection component 1 comprising an inner support member 2 and an outer support member 3 fixedly connected to the outer side of the inner support member 2, the inner support member 2 is tightly attached to the outer peripheral side of the bridge pier, and the two ends of the outer support member 3 are welded to the two ends of the inner support member 2, so that a connection groove 4 is arranged between the inner support member 2 and the outer support member 3; a plurality of energy dissipation members 5 are evenly arranged at intervals in the connection groove 4, one side force-bearing end of the energy dissipation member 5 is connected to the inner support member 2, and the other force-bearing end is connected to the outer support member 3, and rubber concrete 6 is poured between adjacent energy dissipation members 5, so that when an external object such as a vehicle impacts the protection component 1, a large amount of external force is consumed by the energy dissipation member 5 and the rubber concrete 6 in the process of being transmitted to the inner support member 2, thereby reducing the impact force on the bridge pier and avoiding damage to the bridge pier. Among them, rubber concrete 6 has the advantages of better impact energy absorption capacity, durability, crack resistance, freeze-thaw resistance and light weight. At the same time, the added rubber aggregate can be made from waste rubber resources such as waste automobile tires, which can effectively reduce environmental pollution and realize resource recycling and reuse.

[0022] As a preferred embodiment, in this embodiment, the protection component 1 is in a concave shape, and two groups of protection components 1 are combined to form a rectangular outer ring, which is tightly attached to the outer peripheral side of the bridge pier, which is also rectangular, to protect it. The bridge pier anti-collision energy dissipation device arranged in a rectangular shape can avoid the conventional cylindrical trajectory of the impact object, which causes a secondary impact on the target lane, and avoids the occurrence of secondary traffic accidents. It also greatly reduces the direct impact of vehicles on it through its own excellent energy dissipation capacity, and avoids causing a lot of damage to the bridge pier.

[0023] Preferably, the energy dissipation part 5 includes a connecting part 7 located in the middle, an energy dissipation part 8 symmetrically arranged on both sides of the connecting part 7, and a receiving part 9 located on the other side of the energy dissipation part 8, and the receiving part 9 is used to install the energy dissipation part 5 in the connecting groove 4; the energy dissipation part 8 is arranged in a semicircular ring, and one end of the ring top is connected to the connecting part 7. Among them, the inner support 2, the outer support 3, the energy dissipation part 8 and the receiving part 9 are low-yield point steel parts, which can dissipate energy through plastic deformation after bearing external force, and its yield point is less than or equal to Q100. Preferably, the receiving part 9 can well bear and transmit the external force to the energy dissipation part 8 through a large contact area with the groove wall of the connecting groove 4, and the semicircular energy dissipation part 8 is used for yielding and dissipating energy. Due to its strong external force bearing capacity, it can withstand huge external force even in an instant, and quickly consume it during bending deformation, thereby avoiding damage to the bridge pier caused by vehicles.

[0024] Preferably, the energy dissipation part 5 further includes side baffles 10, which are symmetrically arranged on both sides of the energy dissipation part 8, and are arranged in an arc shape, and the two ends of the side baffles 10 are respectively connected to the receiving parts 9 on both sides. The side baffles 10 are also low yield point steel parts, which can also further yield and dissipate energy when the energy dissipation part 5 receives external force, and by arranging the side baffles 10 on both sides of the energy dissipation part 8, it is possible to prevent the rubber concrete 6 from entering the energy dissipation part 8 during pouring, reduce the space for its deformation, and thus affect the energy dissipation capacity of the energy dissipation part 8.

[0025] Preferably, both sides of the connecting portion 7 are recessed inward to form an arc-shaped portion 11. By providing the arc-shaped connecting portion 7 between the two energy consuming portions 8, not only can the energy consuming effect be produced, but also the ends of the two energy consuming portions 8 can be better contacted to conduct energy, and the ends of the energy consuming portions 8 can be strengthened, thereby preventing the main force-bearing position of the energy consuming portion 8 from being directly damaged due to huge external force without producing an energy consuming effect.

[0026] Preferably, a plurality of protrusions 12 are evenly spaced on the two inner side walls of the connecting groove 4; a groove 13 is provided on the outer end of the receiving portion 9, and the energy absorbing component 5 is installed in the connecting groove 4 by fitting and connecting the groove 13 and the protrusion 12. By providing the protrusion 12 and the groove 13, the various components of the protective assembly 1 can be produced on the production line in advance, and then assembled and installed on site, so that the assembly of the anti-collision energy absorbing device can be completed quickly. Among them, the assembly of the energy absorbing component 5 can be completed by fitting the grooves 13 on both sides of the energy absorbing component 5 into the protrusions 12 in the connecting groove, and the protrusions 12 as an embedded assembly are provided on the connecting groove 4 to avoid the appearance of weak points in the outer support component 3 as the primary force-bearing component, thereby ensuring that the outer support component 3 can withstand the external force without being directly damaged and failing to transfer energy to the energy absorbing component 5 for energy consumption.

[0027] Preferably, a plug-in portion 14 is protrudingly provided at one end of the protection component 1, and a slot portion 15 is provided at the other end. The plug-in portion 14 and the slot portion 15 can be adapted to be connected, and a plurality of bolt holes are correspondingly provided on the plug-in portion 14 and the slot portion 15. By providing the plug-in portion 14 and the plug-in slot, two sets of protection components 1 can be quickly connected, and the installation can be quickly completed by docking the bolts with the bolt holes. Among them, after the rubber concrete 6 is poured, it can be encapsulated by installing a sealing plate on the upper end of the connection slot 4.

[0028] Preferably, as an implementation mode, the rubber aggregate in the rubber concrete 6 accounts for 50% by mass, thereby ensuring the ductility and impact resistance of the rubber concrete 6. There are many ways to mix the remaining materials such as cement, sand, gravel, water, and water reducer, which will not be elaborated here.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
