Abstract

The invention discloses an encapsulated combined guardrail. The encapsulated combined guardrail comprises an old guardrail wall and an encapsulated guardrail wall. The old guardrail wall is connected with the encapsulated guardrail wall through embedded bars. The head-on collision face of the old guardrail wall is located inside the encapsulated guardrail wall. Encapsulated ribs are arranged in the encapsulated guardrail wall. The encapsulated combined guardrail has the beneficial effects that by arranging the encapsulated guardrail wall on the head-on collision face of the old guardrail wall, the old guardrail wall material is fully utilized, the modified construction cost is lowered, and the anti-collision grade of the guardrail is improved; and the road side is completely made of new concrete, and therefore the encapsulated combined guardrail is more attractive in appearance and better in landscaping performance.

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...
