Anti-collision structure of outer side guardrail of sharp turn lane

Abstract

The invention provides an anti-collision structure of an outer side guardrail of a sharp turn lane, and belongs to the field of road traffic facilities. The structure comprises a right-angle sharp turn lane, an outer side guardrail, a floating body, a rotating device, energy dissipation layers, a light thin-wall energy dissipation pipe, a light energy dissipation material, an elastic rotating shaft, rubber rotating columns, an upper sealing plate, a roller, a rolling shaft, a damping elastic steel frame, a smooth continuous transition belt, a binding penetrating rope and built-in filling softwadding. In the anti-collision structure of the outer side guardrail of the sharp turn lane, the outer side guardrail is arranged on the outer side of the right-angle sharp turn lane, the floating body is arranged on the inner side of the outer side guardrail; the several rubber rotating columns are arranged, and two thirds of the volume of each rubber rotating column is arranged in the floating body; and the anti-collision structure has the advantages that the acting time of a vehicle and the outer side guardrail can be prolonged through the multiple energy dissipation layers, the arranged rotating device and the rubber rotating columns are beneficial for fully changing the moving direction of the vehicle, the guardrail can be protected, the vehicle can be protected, and impact force is changed into rolling friction to the maximum extent.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, and in particular relates to an anti-collision structure for an outer guardrail of a sharp-turning lane. Background technique [0002] With the development of the national economy, a large number of roads and expressways have been built or are under construction. So at present, the protective devices on the outside of expressways and highways are basically made of ordinary protective guardrails, and the protective plates on the protective guardrails are made of steel plates, which are rigid materials. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on the outside of the expressway or rushing into the opposite lane to crash. But practice has proved that the protective plate of the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the protect...

AI Technical Summary

Problems solved by technology

At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited.

And the guardrail board is easy to break under the impact of the car, causing the guardrail to be unable to use normally, and it is also easy to cause secondary damage to the safety of the vehicle and the crew. The problem of limited deformability and energy absorption capacity has become a problem to be solved by those skilled in the art
