High Speed Safety Guardrail

How to deal with the end of High Speed Safety Guardrail?

The starting point of High Speed Safety Guardrail and the standard section guardrail can be connected through the gradient section, then, how to deal with the end of High Speed Safety Guardrail?

The end of the gradient section of High Speed Safety Guardrail is generally designed as a parabola shape, the position of the column is gradually moved out, the height of the column is unchanged, the spacing is encrypted to 2m near the end, the concrete foundation is used, the cable end anchor is added, this treatment is called the end oblique spread round head end treatment.

The use of round head end is more common, because it is easy to manufacture, convenient to install, and has better guiding function in the case of small collision Angle. If the out-of-control vehicle collides with the front of the end, there may be an accident in which the guardrail penetrates the carriage. Therefore, the ground anchor end is used instead, which is gradually extended into the ground through an angled beam and anchored at the end with a concrete foundation. When the out-of-control vehicle crashes head-on, the vehicle will climb along the oblique waveform beam and absorb energy. In the case of side impact, it also has a good guiding function. There are also different treatment methods in the upstream of the forward direction and the downstream of the forward direction, and the ground anchor end treatment method refers to the upstream of the forward direction. The downstream end of the driving direction is arranged in a straight line with the standard section guardrail, and the downstream end is generally processed by the round-head end. The treatment of the end of the corrugated guardrail plate is very important.
