Abstract

The invention provides a mountainous highway cliff-falling-preventing traffic protection structure, which belongs to the field of mountain highway traffic facilities, and comprises a curb cliff-impact-prevention device, a bottom mounting support seat, a cliff-impact-prevention protection structure, a rotary turning anti-collision soft column, a combined buffer rebound net layer, a reinforcing support plate, a silica gel outer pad, a rubber energy dissipation ring column, a rock wool pad and a soft fabric layer, wherein the base base plate is arranged on the uppermost portion, the two verticalrows of fixing holes are formed in the left side of the base base plate, the vertical rows of lower inserting holes are formed in the right side of the base base base plate, the installation verticalplate is arranged below the base base base plate and perpendicularly connected with the base base base plate, and the row of installation holes are formed below the installation vertical plate. The mountainous highway cliff-falling-preventing traffic protection structure is advantageous in that the mounting operation is remarkably simplified; the mountainous highway cliff-falling-preventing traffic protection structure is high in assembly speed, capable of being replaced quickly, quite convenient to disassemble industrially, good in overall structure coordination and connection performance, capable of effectively draining water and retarding flame, and capable of damping and dissipating energy to greatly buffer impact force, improving the safety performance of a vehicle body and reducing energy exchange between the vehicle body and the anti-collision guardrail.

Description

technical field

[0001] The invention belongs to the field of mountain road traffic facilities, in particular to a traffic protection structure for preventing falling off cliffs on mountain roads. Background technique

[0002] There are many mountain roads in my country, and most of the mountain roads are located near cliffs. These are the factors that cause vehicles to crash into cliffs. There are many famous mountain roads in China, and they are also very dangerous. There are not a few mountain roads that have had major traffic accidents. The Huanghuaqiao section of Jiangxi National Highway 320 is located in Xiangdong District, Pingxiang City, Jiangxi Province. The length is less than 1 kilometer, but it is called The "Devil's Zone" had frequent accidents before the reconstruction, which made everyone who went there have lingering fears. In 2003, the road was listed by the Ministry of Public Security and the State Administration of Work Safety as one of the 29 dangerous ro...
