Abstract

The beam type regeneration buffer guardrail comprises two supporting columns and at least one buffer beam, the two supporting columns are arranged at the two ends of the buffer beam respectively, the buffer beam is arranged in the height direction in a spaced mode, and the two ends of the buffer beam are connected with the supporting columns respectively; the buffer beam comprises a regenerated buffer energy-absorbing material and a shell, the regenerated buffer energy-absorbing material is prepared by taking construction waste as a raw material, the interior of the shell is filled with the regenerated buffer energy-absorbing material, and the shell is fixedly connected with the supporting column; and the shell is made of a glass fiber material. The method has the beneficial effects that the bending rigidity of the beam is improved, the lateral bearing capacity is enhanced, the distance between the beam and the ground is reduced, and building solid waste is absorbed; on the premise of giving consideration to buffering and guiding functions of the guardrail, the blocking function of the guardrail is improved, and vehicles are prevented from straddling, breaking by collision or entering the guardrail.

Description

technical field [0001] The invention relates to a guardrail device, in particular to a beam-type regenerative buffer guardrail. Background technique [0002] The anti-collision guardrail is an essential facility to ensure the safe, comfortable and fast operation of the road, especially the expressway. At present, one of the most common anti-collision guardrails on expressways in my country is the wave beam guardrail. The wave beam guardrail is mostly a steel plate structure with a very small cross-sectional area and weak blocking function. The guardrail is broken, and the distance between the wave beam guardrail and the ground is large. For miniature vehicles, they may get under the guardrail or jump out of the guardrail, and the safety is poor. Therefore, it is necessary to improve the prior art. Contents of the invention [0003] The object of the present invention is to provide a safe and reliable beam-type regenerative buffer barrier against the deficiencies of the pr...
