Technical Field
The invention relates to a highway anti-collision guardrail, belongs to the field of traffic road safety facilities, and particularly relates to a buffer type highway guardrail.
Background
Road safety barriers, also known as traffic barriers, are generally classified into flexible barriers, semi-rigid barriers, and rigid barriers, where flexible barriers generally refer to cable barriers, rigid barriers generally refer to concrete barriers, and semi-rigid barriers generally refer to beam barriers. The semi-rigid guardrail is a continuous beam column structure, the main representative form of the semi-rigid guardrail is a waveform guardrail, and the waveform beam guardrail is most widely applied from the practical application conditions at home and abroad.
The purpose of constructing a road safety barrier represented by a waveform barrier is to protect vehicles and persons in the vehicles from being collided by natural or artificial objects beside a road. In fact, however, the road safety barriers widely distributed on all levels of roads in China cause much damage to vehicle owners due to the defects in design and position planning. Once a vehicle collides with a safety guardrail carelessly, the safety guardrail is broken easily due to the fact that the guardrail is crashed, particularly, a connecting elbow of the safety guardrail is deformed suddenly in the process of crashing and is folded into a shape like a cone triangle, the broken guardrail penetrates through a vehicle window and a vehicle body and further penetrates through the vehicle body to endanger the personal safety of people in the vehicle, so that serious secondary injury is caused, and too many accidents of vehicles colliding with the guardrail and the guardrail cause death on domestic roads. It is clearly very alarming that the accident of secondary injury is caused by the accident of the vehicle and the collision of the vehicle on the safety guard rail of the highway.
Disclosure of Invention
The invention provides a buffer type highway protective guard for solving the problems of a highway safety protective guard represented by a waveform protective guard in the prior art, which integrates vehicle guiding, protecting, buffering and energy absorbing into a whole.
In order to achieve the purpose, the invention adopts the following technical scheme:
a buffer type highway protective guard comprises a plurality of collision-proof columns distributed at equal intervals, wherein the lower ends of the collision-proof columns are fixedly connected with a road surface through pre-buried collision-proof column bases, and a plurality of buffer supporting components are arranged at equal intervals from top to bottom on the collision-proof columns; be equipped with the support column subassembly between two adjacent last buffering supporting component's of anticollision post outer end, the support column subassembly on be equipped with three direction rotary drum, the rubber cushion collar that is equipped with is overlapped in the outside of direction rotary drum, the surface of rubber cushion collar be equipped with the conical skid proof block of a plurality of. The vehicle running at high speed slightly collides the protective guard, and the guide rotating cylinder guides the vehicle to enter the front rail for running; when the collision is severe, the guide rotary cylinder deforms, collapses, buffers and absorbs energy, and simultaneously the buffer support component deforms and absorbs energy, so that the collision force of the vehicle is reduced; when violent collision occurs, the guide rotating cylinder, the buffer support assembly and the anti-collision column buffer, absorb energy and collapse to play multiple protection roles, so that vehicles are prevented from rushing out of guardrails or rushing into driveways of roads reversely as far as possible, and casualties caused by traffic accidents are effectively reduced.
