[0029] However, when assembling existing highway corrugated beam guardrails, each guardrail is usually connected end to end, bolted together, and then fixed to the column by bolts. However, by adopting this connection method, when a vehicle hits the guardrail, the guardrail has weak impact resistance at the connection point and is easily broken, resulting in reduced protection effect. Moreover, the above-mentioned arrangement enhances the bearing capacity of the corrugated steel guardrail plate by inserting a steel cable loop between the two columns. When the guardrail plate is broken, the guardrail needs to be punched again and matched with a guardrail plate of corresponding length before it can be used, so that the broken guardrail lacks protection and cannot absorb the impact force of the vehicle.

[0030] like Figure 1-5 As shown, the highway corrugated beam guardrail which is easy to restore and reinforce includes a guardrail body 100 distributed up and down, and a reinforcing plate 301 is provided on the other side of the guardrail body 100 opposite to the impact surface; a slider 300 is provided on the reinforcing plate 301; the slider 300 is hung on the buffer structure 200; and the shell 203 at one end of the buffer structure 200 is sleeved on the upper end of the column 101. When a vehicle hits and breaks the guardrail body 100, the slider 300 is slid into the slide groove of the intact reinforcement plate 301, and the column 101 is sleeved in the shell 203, so that the guardrail body 100 can continue to be used, which is convenient for rapid recovery and makes the guardrail body 100 have anti-collision capability again. Secondly, by arranging a plurality of supporting structures 400 on the arc-shaped inner wall of the guardrail body 100, the anti-collision capability of the guardrail body 100 is improved. Furthermore, by arranging a buffer structure 200 between the guardrail body 100 and the column 101, when a vehicle collides with the guardrail body 100, the buffer structure 200 can absorb the impact force of the vehicle on the guardrail body 100 and play a buffering role in the impact of the vehicle.

[0031] Specifically, the buffer structure 200 includes a buffer shell 201 and a plurality of energy absorbing strips 202. The buffer shell 201 is provided with a plurality of energy absorbing strips 202 at the upper and lower ends. The energy absorbing strips 202 press the U-shaped undercut of the slider 300 against the inner side of the edge of the buffer shell 201. The upper and lower guardrail bodies 100 are fixedly connected with a reinforcing plate 301. The slider 300 can slide in a slide groove provided in the reinforcing plate 301. A plurality of anti-collision wheels 102 are provided between the upper and lower guardrail bodies 100. When a vehicle loses control and collides with the guardrail body 100, the vehicle first contacts the anti-collision wheel 102, generates friction with the anti-collision wheel 102, drives the anti-collision wheel 102 to rotate, and the anti-collision wheel 102 first reduces the speed of the vehicle. To cushion the impact of the vehicle on the guardrail body 100, when the impact force of the vehicle is large, the anti-collision wheel 102 and the guardrail body 100 cannot withstand the impact force of the vehicle, so the guardrail body 100 pushes the reinforcing plate 301 to one side to move toward the column 101, and the reinforcing plate 301 is fixed between the upper and lower guardrail bodies 100 to improve the anti-collision ability of the guardrail body 100. As the vehicle moves, the reinforcing plate 301 squeezes the buffer shell 201, and the buffer shell 201 and the multiple energy-absorbing strips 202 inside the buffer shell 201 absorb the energy of the vehicle impact and mitigate the impact force of the vehicle, thereby protecting the passengers in the car and avoiding direct rigid impact to cause harm to the passengers.

[0032] Secondly, each supporting structure 400 is composed of an arc-shaped plate 403 and a plurality of supporting plates 404, wherein the plurality of supporting plates 404 are fixedly connected to a sleeve 405 on one side, and a cavity is formed between the arc-shaped plate 403 and the adjacent supporting plates 404, and the sleeve 405 is sleeved on the connecting rod 401 through a first through hole 406, and the connecting rods 401 at both ends of the sleeve 405 are sleeved with a limiter 402 for limiting the movement of the sleeve 405, and the bolts threadedly connected to the connecting rod 401 hold the limiter 402 against the limiter. When assembling the guardrail body 100, By putting a limiting piece 402 on the connecting rod 401 of the arc-shaped inner wall at the joint of adjacent guardrail bodies 100, the two limiting pieces 402 are respectively located at the two ends of the sleeves 405 on both sides, and then, the bolts are respectively screwed into the connecting rod 401 so that the bolts can hold the limiting pieces 402. When a vehicle hits the arc-shaped plate 403, the blocking rods 4022 of the limiting pieces 402 on both sides can limit the sleeves 405 to prevent the supporting structure 400 from sliding on the connecting rod 401, thereby reducing the impact resistance of the guardrail body 100. At the same time, since one end of the blocking rod 4022 is welded to the arc-shaped inner wall of the guardrail body 100, the connecting rod 401 is fixed to the guardrail body 100; and the connecting rod 401 is used to support the supporting structure 400, so when a vehicle hits the guardrail body 100, the arc plate 403 and the support plate 404 provide support for the guardrail body 100, enhance the bearing capacity of the guardrail body 100, make the guardrail body 100 not easy to break, and effectively ensure the integrity of the guardrail body 100.

[0033] Secondly, this assembly method is convenient and quick. It only requires the arc plate 403 to be sleeved on the connecting rod 401 through the first through hole 406, and then the limiting member 402 is also sleeved on the connecting rod 401 through the second through hole 4023, so that the two sides of the arc plate 403 can be abutted, and finally the limiting member 402 can be limited by bolts. After the above assembly is completed, the horizontal position of the arc plate 403 and the limiting member 402 has been limited and cannot be moved; then the blocking rod 4022 on the limiting member 402 can be welded to the guardrail body 100. This method has fewer welding points, simple on-site operation process, and improved installation efficiency.

[0034] In summary, the working principle of the present invention is as follows: first, bury the adjacent upright posts 101 in the earth pit respectively, then, put the shell 203 on the guardrail body 100, the U-shaped inverted edge of the slider 300 is held against the energy absorbing strip 202 on one side of the buffer shell 201, align the slide groove 302 in the reinforcing plate 301 with the T-shaped sliding end of the slider 300, so that the two ends of the reinforcing plate 301 are pulled by the sliders 300 on both sides, and when the adjacent guardrail bodies 100 are fitted, two limit members 402 are put on the connecting rod 401 at the connection, and the two limit members 402 are respectively located on the sleeves 4 on both sides. 05 ends, and then, the bolts are screwed into the connecting rod 401 respectively, so that the bolts hold the limiter 402 against the limiter 402 to prevent the limiter 402 from sliding on the connecting rod 401 when the vehicle hits the arc plate 403, thereby reducing the impact resistance of the guardrail body 100. The sleeve 405 connects the adjacent connecting rods 401 together. Then, when the vehicle loses control and hits the guardrail body 100, the vehicle first contacts the anti-collision wheel 102, and friction is generated between the anti-collision wheel 102, driving the anti-collision wheel 102 to rotate. The anti-collision wheel 102 first slows down the impact of the vehicle on the guardrail body 100. The arc plate 403 and the support plate 404 provide support for the guardrail body 100, enhance the bearing capacity of the guardrail body 100, make the guardrail body 100 not easy to break, and effectively ensure the integrity of the guardrail body 100. When the impact force of the vehicle is large, the anti-collision wheel 102 and the guardrail body 100 cannot withstand the impact force of the vehicle, so the guardrail body 100 pushes the reinforcing plate 301 to one side to move toward the column 101. The reinforcing plate 301 is fixed between the upper and lower guardrail bodies 100 to improve the anti-collision ability of the guardrail body 100. As the vehicle moves, the reinforcing plate 301 is fixed between the upper and lower guardrail bodies 100 to improve the anti-collision ability of the guardrail body 100. The plate 301 squeezes the buffer shell 201, and the buffer shell 201 and multiple energy-absorbing strips 202 inside the buffer shell 201 absorb the energy of the vehicle collision and reduce the impact force of the vehicle, thereby protecting the passengers in the car and avoiding direct rigid collision to cause harm to the passengers. When the vehicle breaks the guardrail body 100, the slider 300 slides into the slide groove of the intact reinforcement plate 301, the slider 300 is supported by the energy-absorbing strip 202, and the column 101 is sleeved in the shell 203, so that the guardrail body 100 can continue to be used, which is convenient for rapid recovery and makes the guardrail body 100 have anti-collision ability again.
