[0002] Vehicle collisions with bridges can cause casualties, damage to bridges, traffic disruptions and other negative socio-economic impacts. Setting up independent anti-collision devices on bridges so that vehicles do not directly collide with the bridges but collide with the anti-collision devices first is a feasible way to protect bridges.

[0003] Bridge guardrails are a common bridge anti-collision safety device, usually installed on both sides of the bridge. When a car collides with the bridge, the guardrails can effectively prevent the car from rushing out of the bridge. Existing bridge guardrails are generally fixed directly on the bridge deck. When a vehicle collides with the guardrail, the guardrail absorbs kinetic energy through deformation, slowing down the impact of the guardrail on the vehicle.

[0004] The disadvantages of the above existing technical solutions are that traditional bridge guardrails are mostly made of metal materials or ordinary concrete materials. Although these materials have certain strength and toughness, when a vehicle collides with the guardrail made of these materials, it often generates a large impact force.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, a bridge anti-collision device based on construction solid waste includes a recycled buffer material 1, a fixed base 2, a support column 3, a movable cover plate 4 and an anti-collision rod 5. A buffer groove 6 is provided on the top of the fixed base 2, and the recycled buffer material 1 is cast in the buffer groove 6. The bottom of the support column 3 is slidably set in the buffer groove 6. The movable cover plate 4 is matched and set at the notch of the buffer groove 6. The anti-collision rod 5 is fixedly set on the side of the support column 3 in a horizontal state. A cavity 7 is provided inside the anti-collision rod 5, and the recycled buffer material 1 is cast inside the inner cavity. The recycled buffer material 1 includes water, a foaming agent and recycled sand. The preparation process of the recycled buffer material 1 used in the present invention is: a foaming machine is used to produce fine and uniform foam, which is mixed with a mixture of fiber, recycled sand, water and cement according to a construction mix ratio and sent to a concrete mixer for stirring to prepare the recycled buffer material 1. The recycled sand is any kind of construction waste such as discarded concrete blocks, mortar blocks, bricks and tiles, stones, and glass.

[0031] When the vehicle accidentally collides with the anti-collision bar 5, the anti-collision bar 5 is impacted first. Since the anti-collision bar 5 is also filled with the recycled buffer material 1, this part of the material begins to absorb and disperse the energy generated by the collision. At the same time, the sliding design of the support column 3 in the buffer groove 6 allows it to have a certain displacement when it is impacted, which further disperses the impact force and reduces the energy directly transmitted to the fixed base 2.

[0032] As the support column 3 moves, the regenerative buffer material 1 at the bottom thereof is compressed to further absorb energy. The design of the movable cover plate 4 ensures the closedness of the buffer groove 6, while allowing a certain deformation during the collision process to adapt to the displacement of the support column 3. During the whole process, the regenerative buffer material 1 converts the collision energy into the deformation energy of the material, thereby greatly reducing the impact on the vehicle and passengers.

[0033] Compared with traditional metal materials or ordinary concrete materials, the recycled buffer material 1 used in the present invention can absorb energy more effectively during a collision, reducing the risk of secondary injury to vehicles and passengers. The recycled buffer material 1 is mainly made of construction solid waste (such as discarded concrete blocks, mortar blocks, bricks and tiles, stones, glass, etc.), which not only reduces the cost of processing construction waste, but also realizes the recycling of resources, which is in line with the concept of sustainable development. The use of recycled materials to prepare anti-collision devices can significantly reduce material costs. At the same time, the design of the device is simple and practical, and it is easy to install and maintain.

[0034] refer to Figure 2 As shown, in some specific embodiments, a first slide groove 8 and a second slide groove 9 are provided inside the buffer groove 6. The first slide groove 8 is oriented perpendicular to the direction of the bridge and is mainly used to absorb impact forces perpendicular to the direction of the bridge. The second slide groove 9 is oriented parallel to the direction of the bridge and is mainly used to absorb impact forces parallel to the direction of the bridge. The support column 3 is connected to the first slide groove 8 and the second slide groove 9 by sliding cooperation. The first slide seat 10 and the second slide seat 11 are respectively slidably arranged in the first slide groove 8 and the second slide groove 9, and the first slide rod 12 and the second slide rod 13 are respectively fixedly arranged on the sides of the first slide seat 10 and the second slide seat 11, and the bottom of the support column 3 is provided with a first slide hole and a second slide hole that are respectively slidably matched with the first slide rod 12 and the second slide rod 13.

[0035] The first slide seat 10 and the second slide seat 11 are the connection points between the support column 3 and the buffer groove 6, ensuring that the support column 3 can slide smoothly in the buffer groove 6 when subjected to impact force. Through the first slide hole and the second slide hole at the bottom of the support column 3, the support column 3 has a certain degree of freedom of displacement in both directions perpendicular to and parallel to the bridge, thereby more effectively dispersing and absorbing the collision energy.

[0036] When a vehicle collides with the crash bar 5, the impact force is first partially absorbed by the regenerative buffer material 1 in the crash bar 5. Subsequently, the support column 3 converts the remaining impact force into the kinetic energy of the first slide 10, the second slide 11 and the support column 3 and the deformation energy of the regenerative buffer material 1 through the sliding of the first slide 10 and the second slide 11 in the first slide groove 8 and the second slide groove 9. This energy conversion process greatly reduces the impact force directly transmitted to the fixed base 2 and the bridge structure.

[0037] Through the first slide groove 8 and the second slide groove 9 and the corresponding slide seat and slide rod, the present invention can more effectively absorb and disperse the collision energy, thereby further reducing the potential damage to the vehicle and passengers. Since the first slide groove 8 and the second slide groove 9 are oriented perpendicularly and parallel to the bridge respectively, this design enables the anti-collision device to better adapt to collisions at different angles, thereby improving its versatility and practicality in practical applications.

[0038] refer to Figure 3 As shown, in some specific embodiments, the movable cover 4 includes a first plate body 14, a second plate body 15 and a third plate body 16, a first card slot 17 and a second card slot 18 are provided on the top of the fixed base 2, a third card slot 19 is provided on the side of the first plate body 14, a fourth card slot 20 is provided on the side of the second plate body 15, the first plate body 14 is connected to the first card slot 17 by sliding fit, the second plate body 15 is connected to the second card slot 18 by sliding fit, and both ends of the third plate body 16 are connected to the third card slot 19 and the fourth card slot 20 by sliding fit respectively. The orientation of the first card slot 17 and the fourth card slot 20 is parallel to the orientation of the bridge, and the orientation of the second card slot 18 and the third card slot 19 is perpendicular to the orientation of the bridge.

[0039] The movable cover plate 4 is used to isolate the regenerated buffer material 1 in the buffer groove 6 from the outside world to protect these materials from erosion and damage by the external environment. When the vehicle collides with the anti-collision bar 5, since the impact force may come from different directions, the first plate body 14, the second plate body 15 and the third plate body 16 are separated from each other when they are impacted, thereby preventing the entire movable cover plate 4 from being damaged due to excessive impact force.

[0040] refer to Figure 6 As shown, in some specific embodiments, a limiting clamping sleeve 21 is fixedly provided on the side of the fixed base 2, and a movable clamping block 22 is slidably provided in the limiting clamping sleeve 21, and the side of the movable clamping block 22 abuts against the movable cover plate 4. A spring 23 is fixedly provided on the limiting clamping sleeve 21, one end of the spring 23 is connected to the movable clamping block 22, and the other end of the spring 23 is connected to the limiting clamping sleeve 21.

[0041] When no collision occurs, the movable block 22 is in contact with the movable cover plate 4 by the tension of the spring 23, thereby effectively limiting the sliding of the movable cover plate 4. This ensures that the regenerated buffer material 1 in the buffer groove 6 can always be protected from erosion and damage by the external environment.

[0042] When the vehicle collides with the anti-collision rod 5, the movable cover plate 4 presses the movable block 22 to compress the spring 23, and the restriction of the movable block 22 on the movable cover plate 4 is cancelled, thereby preventing the entire movable cover plate 4 from being damaged due to excessive impact force.

[0043] refer to Figure 4As shown, in some specific embodiments, a reinforcing rib 24 is fixedly provided on the side of the support column 3. The reinforcing rib 24 is used to improve the bending, shear and compression resistance of the support column 3. In the bridge anti-collision device, the support column 3 is a key component that withstands the impact force of vehicle collision, and its structural strength and stability are of great importance. The design of the reinforcing rib 24 can significantly enhance the bearing capacity of the support column 3, so that it can better maintain a stable shape when subjected to external forces, thereby extending the service life of the anti-collision device.

[0044] refer to Figure 5 As shown, in some specific embodiments, a plurality of anti-collision bars 5 are provided, and are arranged longitudinally on the side of the support column 3. And the anti-collision bars 5 are cylindrical in structure. The longitudinally arranged anti-collision bars 5 not only improve the overall strength of the anti-collision device, but also enable the impact force to be dispersed among multiple anti-collision bars 5, thereby reducing the risk of damage to a single anti-collision bar 5. When subjected to impact force, the cylindrical anti-collision bar 5 can effectively absorb and disperse energy through its cylindrical shape. This structure enables the anti-collision bar 5 to better resist deformation during a collision, thereby protecting the support column 3 and the bridge structure from damage.

[0045] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0046] When the vehicle accidentally collides with the anti-collision bar 5, the anti-collision bar 5 is the first to be impacted. Since it is filled with regenerated buffer material 1, this part of the material can quickly absorb and disperse the energy generated by the collision. At the same time, the sliding of the support column 3 in the buffer groove 6 enables it to produce a certain displacement when it is subjected to impact force, thereby further dispersing the impact force and reducing the energy transmitted to the fixed base 2. As the support column 3 moves, the regenerated buffer material 1 at its bottom is compressed and continues to absorb energy. While ensuring the closedness of the buffer groove 6, the movable cover plate 4 can produce a certain deformation during the collision process to adapt to the displacement of the support column 3. During the whole process, the regenerated buffer material 1 greatly reduces the impact on the vehicle and passengers by converting the collision energy into its own deformation energy.

[0047] Compared with traditional metal materials or ordinary concrete materials, the recycled buffer material 1 used in the present invention has a more significant effect in absorbing energy during a collision, and can effectively reduce the risk of secondary damage to vehicles and passengers. Moreover, the recycled buffer material 1 is mainly made of construction solid waste, which not only reduces the cost of processing construction waste, but also realizes the recycling of resources, which fully conforms to the concept of sustainable development. The use of recycled materials to prepare the anti-collision device can significantly reduce the material cost. At the same time, the device is simple and practical in design, and is easy to install and maintain.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
