A filling type crash wall

Abstract

The invention relates to a filling anti-collision wall, which belongs to the field of traffic engineering. The column is perpendicular to the ground and connected to the underground pile foundation. One end of the column is supported by the back support frame. The other end of the column relative to the back support frame is provided with a rear wall; The side of the collision body facing the traffic lane is the collision side, and an energy-absorbing member is arranged between the outer anti-collision body and the rear wall; the outer anti-collision body extends along the roadway construction direction, and the rear wall and the outer anti-collision body The length of the collision body remains the same; the back support frame supports the rear wall in sections. The filling anti-collision wall provided by the invention has reasonable structure, low investment cost, convenient construction and long service life, good energy absorption effect, can effectively absorb high-speed impact energy, and solves the problem that the blocking effect of the existing steel guardrail is not obvious and the steel guardrail Insufficiency in causing secondary injury to personnel and vehicles.

Description

technical field [0001] The invention relates to a filling type anti-collision wall, which belongs to the field of traffic engineering. Background technique [0002] In the existing anti-collision equipment, the steel anti-collision guardrail can absorb part of the energy, but when the vehicle speed is too fast, the steel anti-collision guardrail will lose its protective effect after plastic deformation, and the deformed steel plate is easily introduced into the vehicle to bring damage to the insiders. Danger. [0003] There is also an anti-collision bucket at the road fork, which is filled with sand and gravel. When the vehicle hits, the anti-collision bucket can absorb part of the impact energy, but the volume of the anti-collision bucket is limited. Once the impact occurs, the vehicle will pass through the anti-collision bucket. The crash barrel continued to the outside of the road. [0004] In order to make up for the deficiencies of the existing anti-collision barrels ...
