Abstract
The invention discloses an impact-resistant and corrosion-resistant expressway guardrail and belongs to the field of road construction. The impact-resistant and corrosion-resistant expressway guardrail aims at solving the problems that an existing guardrail is poor in corrosion resistance, low in impact resistance strength and low in safety warning degree and comprises an upright, a corrugated plate, a transverse column and connecting pieces. The upright is connected with convex faces on the upper side and the lower side of the corrugated plate and the concave face in the middle of the corrugated plate through the three connecting pieces. The transverse column is fixed between the portion, provided with the middle connecting piece, of the upright and the corrugated plate. The corrugated plate is composed of the two convex faces and one concave face. The protruding degree of the convex face on the upper side is smaller than that of the convex face on the lower side. The transverse column is located on the side, close to the upright, of the corrugated plate. The transverse column is connected with the upright and the corrugated plate at the position with the upright and connected with the corrugated plate through the connecting pieces at the position without the upright. The upright is made of a metal material. The corrugated plate is made of a glass fiber reinforcement material. The middle of the transverse column is coated with a metal strip. A carbon fiber reinforcement resin material covers the periphery of the transverse column. The connecting pieces are bolts for connection.
