The invention relates to a single-piece type concrete guardrail for a highway. The single-piece type concrete guardrail comprises an upper base, a fixing seat and a lower base in sequence from top to bottom, wherein the upper base, the fixing seat and the lower base are connected into a whole. The two side walls of the upper base and the two side walls of the lower base are both obliquely arranged, so that the sections of the upper base and the lower base are of isosceles trapezoid structures. The fixing seat is of a cuboid structure. A planting cavity with an upward opening is formed in the upper base and internally provided with soil, and shrubs are planted in the soil. A buffer groove with a downward opening is formed in the lower base, and two supporting steel bars are longitudinally arranged between the two side walls of the buffer groove. Two fixing channel sets are formed in the fixing seat. Anti-collision performance and safety performance are improved. 本发明涉及种公路用单片式混凝土护栏，自上而下依次包括连接成体的上基座、固定座和下基座，上基座和下
