Problems solved by technology
[0002] The existing road central guardrail generally has a simple structure, poor protection performance and cushioning performance, and cannot fully absorb collision energy. When an overspeeding or fully loaded vehicle hits the central guardrail of the road, the central guardrail is easily broken, causing the vehicle to Secondary traffic accident caused by head-on collision with other vehicles after crossing the opposite lane
Even if the central guardrail is not broken sometimes, due to the poor cushioning performance of the central guardrail, the vehicle is generally severely damaged, and the people in the vehicle will be seriously injured or directly killed

The invention discloses a double protective fence in the middle of a road. The double protective fence in middle of the road comprises a plurality of pairs of stand columns, corrugated fence inner plates and corrugated fence outer plates; the lower ends of the stand columns are fixed to a road surface; a buffering frame is connected between each pair of stand columns; buffering blocks are fixedly connected to the side wall of the upper end of each stand column; the corrugated fence inner plates are transversely distributed on the two sides of the pairs of stand columns, and are fixedly connected with the buffering blocks at the same time; the corrugated fence outer plates are arranged on the outer sides of the corrugated fence inner plates side by side; and a plurality of compression springs are connected between the inner side faces of the corrugated fence outer plates and the outer side faces of the corrugated fence inner plates. The double protective fence in middle of the road has high protecting performance, a vehicle cannot directly break the double protective fence in middle of the road easily in a rushing manner, meanwhile, good buffering performance is also achieved, it is guaranteed that no serious damage is caused easily after the vehicle rushes into the double protective fence in middle of the road, and the survival rate of personnel in the vehicle is increased.
Description
technical field [0001] The invention belongs to the technical field of road safety equipment, and in particular relates to a double protective fence in the middle of a road. Background technique [0002] The existing road central guardrail generally has a simple structure, poor protection performance and cushioning performance, and cannot fully absorb collision energy. When an overspeeding or fully loaded vehicle hits the central guardrail of the road, the central guardrail is easily broken, causing the vehicle to A secondary traffic accident occurs when the vehicle crosses the opposite lane and collides head-on with other vehicles. Even if the central guardrail is not broken sometimes, due to the poor cushioning performance of the central guardrail, the vehicle is generally severely damaged, and the people in the vehicle will be seriously injured or directly killed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
