Embodiment Construction
[0018] The composite buffer guardrail has a base body 26, and a buffer device is installed on one side of the base body. The buffer device has a nylon inner plate 22, a nylon outer plate 16 and a water bag 19, and the water bag is provided with a water inlet 13 and a pressure valve 17. The two sides of the water bag are respectively movable and crimped with the nylon inner plate and the nylon outer plate, the other side of the nylon inner plate is fixedly connected with the substrate, and the nylon outer plate is articulated with the substrate through the connecting belt 14 . The base body is a reinforced concrete prefabricated body. The length of the base body in the straight section is more than 5 meters. The base body in the turning section should be prefabricated to increase the overall weight and strength and resist the impact force; the nylon inner plate is fixed with the base body through embedded bolts. , the thickness of the nylon inner plate is 5-20 millimeters; the t...
