Automatic separation isolation guardrail in the middle of the road

Abstract

The invention discloses an automatic separation type isolation guardrail in the middle of a road. The automatic separation type isolation guardrail in the middle of the road is characterized in that the automatic separation type isolation guardrail is formed by connecting a plurality of guardrail units; each guardrail unit comprises special-shaped bases, stand columns and a guardrail basic unit, the stand columns are arranged on the two sides of the guardrail basic unit, and the bottom ends of the stand columns are inserted into the special-shaped bases; the top ends of the adjacent stand columns of the adjacent guardrail units are connected in a weak shearing mode through wedged connecting pieces, the interiors of the adjacent special-shaped bases for placement of the adjacent stand columns are connected through torsion devices, and the torsion devices are rotated and separated after being stressed. With the automatic separation type isolation guardrail, not only can opposite-direction traffic flows be separated, but also the safety of the isolation guardrail can be improved; damage to vehicles on opposite-direction traffic lanes generated by overall toppling of the isolation guardrail caused by overlarge collision force between the vehicles is avoided, the influences on the opposite-direction lane capacity are relieved, the safety of drivers and the vehicles is improved, and the effect of non-toppling in slight collision and separation in severe collision is achieved.

Description

technical field [0001] The invention belongs to the technical field of traffic auxiliary facilities, and in particular relates to an automatic separation isolation guardrail in the center of an urban road. Background technique [0002] The acceleration of urbanization and the rapid increase of vehicle ownership have intensified the contradiction between the supply and demand of urban transportation facilities. In order to prevent pedestrians from crossing the street at will, vehicles from turning around at will, and driving in the opposite lane on urban roads, road traffic isolation guardrails are generally set up. my country is the country that uses the most road central barriers in the world. The wide application of urban road central barriers has greatly improved the driving environment and pedestrian order. At the same time, traffic safety problems have become increasingly prominent. Vehicles hit the urban road central barriers Traffic accidents happen from time to time....

AI Technical Summary

Problems solved by technology

The existing methods to reduce the impact of the continuous falling of the isolation guardrail mainly include fixing the base of the isolation guardrail with spikes, or using larger cement stone piers for isolation, but these two methods are not effective in preventing the continuous falling of the guardrail , and the maintenance cost is high

The use of road studs will damage the road surface, and it is easy to fail due to environmental effects such as rainwater erosion for a long time, and the installation is difficult and expensive; the cement pier is large in size, heavy in weight, difficult in transportation, and has little flexibility, so it is difficult to be widely used on roads
