Abstract

The invention discloses a blockage-preventing block and a highly-adaptive guardrail adopting the same. The blockage-preventing block comprises a polygonal frame structure; a polygon formed by the frame structure comprises a first vertical edge; the upper end of the first vertical edge is connected with one end of a first bevel edge, and the lower end of the first vertical edge is connected with one end of a second bevel edge; an included angle formed between the first vertical edge and the first bevel edge is an obtuse angle, and an included angle formed between the first vertical edge and the second bevel edge is an acute angle; and the other end of the first bevel edge is connected with the other end of the second bevel edge through other edges. The blockage-preventing block disclosed by the invention can ensure that the height of a corrugated guard plate is not reduced after a high-speed corrugated guardrail suffers from great impact, thereby ensuring the safety protection capability of the guardrail.

Description

technical field [0001] The invention relates to the field of expressway protection, in particular to an anti-blocking block and a height-adaptive protective fence using the anti-blocking block. Background technique [0002] With the continuous development of our country's economy, the number of urban car ownership continues to increase, and various car accidents on expressways also emerge in endlessly. The inventor has found through research that the limitation of the existing highway guardrails is that it can only be applied to the collision of small vehicles. Large, with strong inertia, once out of control and hitting the highway guardrail, the huge impact force will cause the column fixed with the wave beam to deform and fall along the impact direction, driving the wave guard plate at the current position to lower its height so that the surrounding wave beam A gap is formed in the belt, and a large vehicle out of control will rush out of the road along the gap, which is ...
