Road center fence capable of toppling over safely

Abstract

The invention provides a road center fence capable of toppling over safely. The road center fence comprises a plurality of bases and barrier grid assemblies arranged between every two adjacent bases, each barrier grid assembly comprises two stand columns and barrier grid units arranged between the two stand columns, and adjacent stand columns of every two adjacent barrier grid assemblies are arranged on the same base. The road center fence further comprises steel blocks and pin shafts, the bottoms of the steel blocks are fixedly connected with the corresponding bases, the lower ends of the adjacent stand columns of every two adjacent barrier grid assemblies are arranged between two corresponding steel blocks, arc-shaped grooves are formed in the contact surfaces of the stand columns and the corresponding steel blocks, arc-shaped protrusions matched with the arc-shaped grooves in a clamped mode are formed in the steel blocks, and each pin shaft penetrates through two corresponding steel blocks to connect the steel blocks and the corresponding stand columns. The stability of the road center fence can be guaranteed; when a vehicle collides with the road center fence, the adjacent stand columns rotate to be staggered so that a single barrier grid assembly can topple over safely, the situation that several barrier grid assemblies topple over at the same time, fly to a lane in the opposite direction and cause secondary traffic accidents is avoided, the safety protection effect is achieved, and the traffic safety and traffic efficiency of urban roads are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of traffic auxiliary facilities, and in particular relates to a road central barrier that can be safely dumped. Background technique [0002] With the expansion of my country's urban scale and the rapid growth of motor vehicles in recent years, the conflict between pedestrians and motor vehicles has become more and more serious, pedestrians crossing the road at will and motor vehicles turning around illegally are more and more, so the isolation fence is set in the center of urban roads It is also becoming more common. Existing barriers have two forms of being fixed and not fixed on the road surface, and there are certain defects in these two forms. For the barrier fixed on the road, when the central position of the road changes, its disassembly and reinstallation process is very complicated. At the same time, when the vehicle collides with the barrier, the barrier will transmit the force to the road and caus...

Problems solved by technology

For the barrier fixed on the road, when the central position of the road changes, its disassembly and reinstallation process is very complicated. At the same time, when the vehicle collides with the barrier, the barrier will transmit the force to the road and cause damage to the road surface; The isolation fence on the road surface will fall down when it is subjected to strong wind and car collision, the protection ability will be reduced, and some will even fly to the opposite lane, which will seriously affect the driving safety and traffic capacity of the road.
