Description

Mountain road prevents weighing down cliff traffic protection structure

Technical Field

The invention belongs to the field of mountain highway traffic facilities, and particularly relates to a mountain highway anti-falling cliff traffic protection structure.

Background

A plurality of mountain roads exist in China, most of the mountain roads are located at positions near cliffs, and the mountain roads are all factors causing vehicles to crash the cliffs. The country has many famous mountain highways, and is dangerous at the same time, the mountain highways which have serious traffic accidents do not account for a few, 320 national roads in the Jiangxi are located in the east region of Xiang in the Pingxi province, the Pingxi city, the length is less than 1 kilometer, but the roads are called as 'devil zones', accidents are frequent before reconstruction, and people who have passed are happy and palpitated. In 2003, the road is listed as one of 29 road dangerous road sections in China by the ministry of public security and the national safety production supervision and administration, China has wide breadth, very complex landform and terrain, and numerous mountain forests. Every province has a mountain, so that in order to facilitate the economic development of people during traveling, a mountain road is constructed. Many mountain roads in China are cliff roads, and on the mountain roads, the situations that vehicles rush out of the roads and fall off the cliffs due to sudden accidents or traffic accidents happen occasionally, and the mountain roads also account for a great proportion of the traffic accidents in China. And once the vehicle falls down the cliff, the result of tragedy can happen, which belongs to a serious traffic accident. At present, guardrails are generally adopted for protection, but after a vehicle runs away and hits the guardrail, the guardrail mostly has no obvious buffer function, under the high-speed strong impact force of an out-of-control automobile, the guardrail is broken frequently, the automobile can not be prevented from rushing out of the road and falling off the cliff effectively, meanwhile, the prior protective guards in the market have no obvious buffer and shock absorption functions when in use, and the automobile can only damage and absorb energy by the deformation of the protective guard when colliding the protective guard, the deformation capability and the energy absorption capability of the guardrail are extremely limited, the guardrail is easy to break under the impact action of the automobile, the guardrail cannot be normally used, secondary damage is easy to be caused to the safety of the vehicle and crewmembers, therefore, it is important and imperative to prevent vehicles from rushing out of roads and falling off cliffs due to unexpected accidents or traffic accidents.
