Road guard rail and building method thereof

Abstract

The invention discloses a road guard rail and a building method thereof. The road guard rail comprises upright columns, the lower part of each upright column is fixed on the ground, the upper part facing the road of the upright column is fixed with a tyre, a beam is fixed on the upright column and arranged between two upright column, the side of the beams facing the road is fixed with the tyres vertically in parallel, brackets is fixed on the upright column and arranged on the upper beams and the lower beams, and a guide plate is fixed on the inner wall of the road-facing side of each tyre, and reflective materials are arranged on the external wall of road-facing side of the tyre and / or the guide plate. The building method in the invention is implemented by fixing the brackets on the upright columns, on the upper beams and the lower beams, fixing tyres on the upper beams and the lower beams to form the guard rail. The guard rail built by the method in the invention not only efficiently utilizes waste tyres but also utilizes elastic property of the tyres; the built guard rails the built guard rail has good guidance quality, and can effectively buffer collision; building coast is relatively low, construction is simple and maintenance is easy.

Description

technical field [0001] The invention relates to a guardrail and a construction method thereof, in particular to a road guardrail and a construction method thereof. Background technique [0002] my country, the United States and the European Union are in the forefront of the world's waste tire production. Statistics show that in 2007, the number of scrapped tires in my country reached 150 million each year, with a total mass of 3.1 million tons. Recycling of waste tires generally includes retreading of waste tires, reclaimed rubber from waste tires, etc. Although the recycling rate of waste tires in my country has increased significantly in recent years, there are still a large number of waste tires that have not been effectively utilized every year, forming "black pollution". [0003] At present, my country's highway construction is advancing to the west and to the mountainous areas. The roads in mountainous areas have poor linear conditions and the roadsides are highly d...

Problems solved by technology

[0004] Most of the existing road guardrails are made of steel and concrete, which are semi-rigid and rigid guardrails. The disadvantage is that once a collision occurs, the probability of vehicle loss and casualties is high; cable guardrails are also commonly used, which are flexible guardrails. The disadvantages are construction costs and high maintenance cost

Although this technical solution can reduce the hazard of direct collision between vehicles and concrete guardrails to a certain extent, because the tires are fixed on the concrete guardrails, the amount of deformation is limited, and the elastic properties of waste tires cannot be fully utilized, and because the orientation of waste tires is not OK, so not widely used
