Technical Field
The invention relates to the technical field of road safety facilities, in particular to a road life safety system and a construction method thereof.
Background
At present, the continuous structure which is spliced mutually through the steel guardrail plates and supported by the main column is used for protecting on a road, and the vehicle can absorb energy when colliding with the continuous structure and is not easy to be knocked down, so that the vehicle and drivers and passengers can be protected.
The utility model discloses a utility model patent that grant publication number is CN206941474U discloses a highway guardrail, and this highway guardrail passes through the spring and assists the guardrail cooperation and plays the effect of buffering, protects the vehicle that hits the guardrail.
The above prior art solution has the following drawbacks: when the spring is compressed to the abutting joint of the steel wires of two adjacent circles, the maximum compression state of the spring is achieved, and the buffer effect can not be achieved any more. Because the magnitude of the acting force absorbed by the spring when the spring is deformed to the maximum compression state is not changed, when the vehicle speed is high or the tonnage is large, the vehicle still has large kinetic energy when the spring reaches the maximum compression state. Therefore, when the vehicle speed is high or the tonnage of the vehicle is large, the guardrail cannot achieve a good protection effect.
