Abstract

The invention discloses an enveloped type combined guardrail. The enveloped type combined guardrail comprises an old guardrail wall and an enveloped type guardrail wall, the old guardrail wall is connected with the enveloped type guardrail wall through embedded steel bars, the collision receiving face of the old guardrail wall is located inside the enveloped type guardrail wall, and enveloping steel bars are arranged in the enveloped type guardrail wall. The enveloped type combined guardrail has the advantages that the enveloped type guardrail wall is arranged on the collision receiving face of the old guardrail wall, so that materials of the old guardrail wall are utilized sufficiently, refit construction cost is saved, the anticollision grade of the guardrail is raised, the road side is fully provided with new concrete, the appearance is more attractive, and landscape performance is better.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to an enclosed combined guardrail. Background technique [0002] There are a large number of combined bridge guardrails in China based on the old specification "Technical Specifications for Design and Construction of Highway Traffic Safety Facilities" JTJ074-93. Due to unreasonable design of these guardrails, there are major safety hazards. "JTG / TD81-2006 canceled this combined guardrail. At the same time, reinforced concrete wall guardrails are mostly used for bridges. After years of application, the reinforced concrete wall guardrails are safe to use and reliable in performance. However, the bottom wall of the combined guardrail built according to the old standard has no recyclable value, and the demolition time is long, which is not conducive to construction. If the original combined guardrail bottom wall is rebuilt, its anti-collision ability needs to be improved, and the la...
