Background
The anti-collision guardrail is an auxiliary structure in bridge engineering, in particular to a guardrail structure arranged on a road, which is used for preventing out-of-limit vehicles from being out of the boundary so as to avoid or reduce casualties and material loss. The guardrail arranged on the bridge not only can improve the safety degree of vehicles running on the bridge, but also can avoid the vehicles from going out of a traffic lane or out of the bridge and secondary accidents.
At present, the common anti-collision guardrails in bridge engineering can be divided into two main categories, namely a concrete guardrail and a steel guardrail:
1. a concrete guardrail. The concrete guardrail has strong protective capability and low construction cost, and is the guardrail structure form which is most widely used at present. However, when the concrete guardrail is applied to a large background of construction in the current rapid construction age, the problems existing in the construction cannot be ignored: the binding amount of the site reinforcing steel bars is large, the high-altitude adjacent side concrete is difficult to pour, the construction safety risk is large, the construction period is long, and the like. In the operation process, the concrete guardrail is easy to have the problems of surface layer cracking and the like, and is not easy to repair.
2. Steel guard rail. The existing steel guardrails are mostly of two types of transverse rod type steel guardrails and steel box type steel guardrails. When the cross rod type steel guardrail is used for a high-rise interchange, the visual shielding effect is poor, panic feeling is brought, and the condition of high-altitude parabolic easily occurs. The steel box type steel guardrail has the integrity stronger than that of the cross bar type guardrail, but the steel consumption is doubled as compared with that of the cross bar type guardrail, a large number of field welding works are available, and most of the field welding works are small-space welding, so that the welding quality is difficult to guarantee, and the later maintenance is difficult.
