Method for protecting highway barrier and highway barrier

Abstract

The invention provides a method for protecting a highway barrier and the highway barrier. The method comprises the following steps: adopting a protecting support made of polymer composites and adopting a barrier made of polymer composites. The protecting support is provided with the same cross sections. A sleeve is fixedly arranged on the upper part of the protecting support and is integrally provided with a frame plate. The barrier is a hollow barrel and both ends of the barrier are respectively sleeved in the sleeve of the protecting support to form the highway barrier. The method is simplein construction. The highway barrier has various functions such as safety protecting, lighting and warning at night, has low manufacturing, installation and maintenance costs and reasonable structuredesign, can play better roles of protecting, lighting and warning at night and can be suitable for various occasions including the bridges where street lamps are not easy to install.

Description

technical field [0001] The invention belongs to roadside guardrail facilities and a protection method, in particular to a road guardrail protection method and a road guardrail integrating safety protection and lighting functions. Background technique [0002] In the prior art, metal iron pipes are often used for the guardrails of highways, especially provincial roads and expressways, and their two ends are inserted into the holes formed on the cement piles to form guardrails, which are used for road protection and edge warning. The cement piles of the railings are distributed on the side of the road or on the isolation piles. In order to play a protective role, the guardrails and the cement piles are generally fixedly connected. The installation and fixing of the above-mentioned existing highway guardrails are relatively cumbersome, and it is difficult to realize the maintenance along the highway, and the protective tube made of metal is easy to be stolen and lost. In addit...

AI Technical Summary

Problems solved by technology

The installation and fixing of the above-mentioned existing highway guardrails is relatively cumbersome, and it is difficult to realize the maintenance along the highway. The metal protective tube is easily stolen and lost.

In addition, road protection boards made of steel are prone to rust and corrosion, and need to be painted with anti-corrosion paint for protection. At the same time, the production of metal road protection boards requires high energy consumption, high emissions, and heavy pollution, and the cost of steel production is high.

If it is necessary to set warning signs on the guardrail of the metal pipe, special painting is required, and the use and maintenance costs are also high
