It is mainly installed between guardrail and post to reduce the crash collision of highway/expressway/roadway.Bock itself is an energy absorbing part,so it could make theguardrail deform gradually during the sudden collisions.thus is conducive to energy absorption, reduce occupant casualties;at the same time,the block could allocate the crash energy to guardrail and post,thereby increase the overall strength and tension of the guardrail system.
U-shaped block is a relatively simple highway guardrail connection,
it is made of strip steel through punching and bending, the
production process is simple, generally with U-shaped post or
C-shaped post collocation to form a high-speed guardrail assembly.
The U-shaped block is connected with the guardrail plate by bolts
on one side and the post on the other, which acts as a link between
the above and the below. It is necessary to tighten both the
transverse guardrail plate and the vertical column, so as to
effectively prevent the runaway vehicle from rushing out of the
road and avoid accidents.
