Bridge guardrail support welding anti-collision fence column steel pipe handrail bracket

The guardrail support is an isolation facility used to close both sides along the line and prevent people, animals and non motor vehicles from entering the highway
It also has the function of absorbing collision energy, forcing the out of control vehicle to change direction and restore it to the original driving direction, so as to prevent it from crossing the road or falling under the bridge
According to its mechanical properties, guardrail protection can be divided into three forms: rigid guardrail, semi-rigid guardrail and flexible guardrail
Anti collision guardrail, as a necessary facility of expressway, has a certain impact on high-speed driving safety, driving comfort, expressway landscape and project cost
Therefore, when constructing expressway, we must fully understand the various characteristics of various anti-collision protection sections, including their anti-collision mechanism, project cost, construction simplicity, maintenance cost, anti dazzle facility setting and communication pipeline configuration
What kind of anti-collision guardrail should be selected for a certain expressway must also be selected in combination with its specific engineering conditions
