Abstract

The invention belongs to the technical field of highway facilities, and in particular relates to a highway safety guardrail. The highway safety guardrail comprises protective rails, protective columns, connecting bands, folding safety fences, connecting locks and a roadbed, wherein the protective columns are anchored to the roadbed; the protective rails are fixed to the upper ends of the protective columns; one end of each connecting band is connected to the corresponding protective rail and the other end of each connecting band is connected to the corresponding folding safety fence; and two safety fences of each folding safety fence are locked by the corresponding connecting lock. When a vehicle driving at high speed hits the highway safety guardrail, the high plasticity of the connectingbands can reduce a certain impact force, and the folding safety fences are completely unfolded and locked by the connecting locks so as to prevent the vehicle from going off the road. In the impact process, the deformation of the connecting bands and the unfolding of the folding safety fences have a cushioning effect on the vehicle and provide road space to form a temporary emergency lane so as to prevent second or more impact by following vehicles.

Description

technical field [0001] The invention belongs to the technical field of road facilities, in particular to a road safety guardrail. Background technique [0002] Transportation plays a fundamental and leading role in the development of the national economy. The Chinese government has always regarded the development of transportation as the focus of national economic construction. The concept that the government has formed is "economic development, transportation first", and the development of transportation is an important step in the development of our country. [0003] With the development of the economy, the traffic continues to develop, and there are more and more driving vehicles. [0004] In recent years, traffic accidents on expressways have occurred continuously. Once an accident occurs to one vehicle, the vehicles driving behind are likely to cause multi-vehicle collisions, resulting in a series of chain accidents. Contents of the invention [0005] In order to s...
