[0002] Road bridges generally consist of several major parts such as subgrade, pavement, bridge, tunnel engineering and traffic engineering facilities. With the booming development of the transportation industry, the number of high-grade highways mainly composed of expressways and first-class highways has been increasing year by year. China's highway industry has entered a new stage with the construction of high-grade highways as the focus.

[0028] Furthermore, as Figure 2 shown, several card slots 16 are horizontally spaced at the rear of each T-shaped skateboard 15, and two first bolts 17 are respectively threaded on both ends of the slide rail 14, and one end of each first bolt 17 slides in the corresponding card slot 16.

[0029] Furthermore, as Figure 7 shown, the fixing component 23 includes a U-shaped limiting block 25, a cover plate 27 is rotatably arranged at the opening of the U-shaped limiting block 25, and a second bolt 28 is in threaded contact between the cover plate 27 and the U-shaped limiting block 25.

[0030] Furthermore, as Figure 7 shown, two bumps 26 are respectively fixed on both sides of the opening of the U-shaped limiting block 25, each bump 26 is made of rubber, and a ball valve 39 is arranged on the anti-collision cylinder 21.

[0031] Furthermore, as Figure 4 shown, the first support component 12 includes a support column 29, and a bottom plate 30 is fixedly arranged at the lower end of the support column 29.

[0032] Furthermore, as Figure 4 shown, a fixing plate 31 is fixedly arranged at the rear end of the support column 29, a support plate 32 is arranged at the lower side behind the support column 29, the support plate 32 contacts the ground, and a shock-absorbing rod 34 is connected between the fixing plate 31 and the support plate 32.

[0035] During use, first, the staff first makes the first support component 12 contact the ground, so as to support the first protection component 10 through the first support component 12; then, according to the actual use needs, the staff adjusts its own length. The staff moves the two second protection components 11, so that the two T-shaped slides 15 slide horizontally inside the slide rail 14, thereby changing the distance between the two second protection components 11 and adjusting the length of the safety protection device; the staff rotates the two first bolts 17, so that one end of each of the two first bolts 17 enters the two corresponding card slots 16 respectively, thereby cooperating with the card slots 16 through one end of the first bolts 17 to limit and fix the T-shaped slides 15 on the slide rail 14 and prevent the two second protection components 11 from moving.

[0036] Secondly, the staff makes the two second support components 13 contact the ground, so as to support the two second protection components 11 respectively through the two second support components 13. First, the two second support components 13 support the two second protection components 11 to support and fix the two ends of the safety protection device, and then the first support component 12 supports the first protection component 10 to support and fix the middle part of the safety protection device, so as to enhance the protection ability of the safety protection device.

[0038] When the safety protection device is impacted, first, a solution is contained in a number of anti-collision cylinders 21 to buffer the impact on the safety protection device and reduce the degree of damage to the safety protection device. Then, a number of pointed blocks 33 are inserted into the ground to strengthen the support of the first support assembly 12 and the two second support assemblies 13 for the safety protection device. Next, two springs 37 connected between the two ends of the support rod 36 and the two fixed frames 35 enable the two second support assemblies 13 and the first support assembly 12 to provide a shock-absorbing and buffering effect on the safety protection device, so as to improve the protection effect of the safety protection device. Finally, two cushion plates 38 are located between the first protection assembly 10 and the two second protection assemblies 11, so that the force received by the second protection assembly 11 can be smoothly transmitted to the first protection assembly 10, and the two second support assemblies 13 and the first support assembly 12 provide a support and buffering effect on the impact force received by the safety protection device. Finally, the damaged anti-collision cylinders 21 on the safety protection device are removed by the staff and replaced with new anti-collision cylinders 21, so that the safety protection device can be reused, and the number of anti-collision cylinders 21 can be removed from the safety protection device, which is beneficial to the transportation and movement of the safety protection device.
