The utility model relates to a rail guard technical field, in particular to rail guard of abnormal shape pipe assembly is strengthened in installation.
Background
The anti-collision guardrail structure is used as basic safety facilities on the highway, and plays an important role in guaranteeing the traffic safety of the highway. The existing highway guardrails mostly adopt the main form of semi-steel guardrails, are usually arranged in the middle or at two sides of a highway, and are of a continuous structure formed by splicing corrugated steel guardrail plates and supporting the corrugated steel guardrail plates by solid upright posts. When the guardrail is collided, the collision kinetic energy is absorbed only by the friction force of the surface of the corrugated steel guardrail plate and the elasticity of the corrugated steel guardrail plate, and the damping time is short in actual collision, so that the guardrail has a poor effect of absorbing the collision energy to decelerate the vehicle, basically only plays a role of stopping the vehicle from rushing out of a road, and has little effect on reducing the damage to the vehicle and drivers and passengers.
The most effective means for improving the safety factor of the road is to decelerate the vehicle by absorbing collision energy through the protective guard in special occasions (such as high-speed running road sections of a racing yard). It is therefore desirable to design a guard rail capable of effectively absorbing kinetic energy of vehicle collision.
