Connecting structure of bridgehead transition section concrete anti-collision guardrail and corrugated steel guardrail, and construction method thereof

Abstract

The invention relates to a connecting structure of a bridgehead transition section concrete anti-collision guardrail and a corrugated steel guardrail, and a construction method thereof. The connectingstructure comprises the concrete guardrail and the steel guardrail, a guardrail pipe is fixedly arranged on the concrete guardrail, a concrete transition wall is poured between the concrete guardrailand the steel guardrail, and a plurality of connecting pieces are fixedly arranged on the concrete guardrail; and a reinforcement cage is pre-buried in the concrete transition wall, the connecting pieces are fixedly connected with the reinforcement cage, a mounting groove is reserved in the side, close to the steel guardrail, of the concrete transition wall, and one end of the steel guardrail isinserted into the mounting groove and fixedly connected with the concrete transition wall. The connection strength of the concrete guardrail and the steel guardrail transition section is improved, thesteel guardrail can be heightened and upgraded conveniently, and the overall safety protection effect of the guardrail is enhanced.

Description

technical field [0001] The present application relates to the field of highway guardrails, in particular to a connection structure and construction method of a concrete anti-collision guardrail and a corrugated steel guardrail in the bridgehead transition section. Background technique [0002] Guardrail is an important safety facility essential to ensure the safety and rapid operation of high-grade highways, and plays an important role in reducing the number of traffic accidents and reducing the severity of accidents. In recent years, the setting level of guardrails on high-grade highways in my country has been greatly improved, but the design and construction level of some guardrails are poor, and they still cannot meet the requirements of the regulations. [0003] At present, for the transition section between the corrugated rigid guardrail (semi-rigid guardrail) and the bridge concrete guardrail (rigid guardrail), most of the guardrails at the transition are randomly over...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the connection between the existing concrete guardrail and the steel guardrail transition section is not firm, and there is a large potential safety hazard, and because the height of the concrete guardrail is determined, it is difficult to upgrade the height of the steel guardrail
