Barrier wall element

Abstract

Disclosed is barrier wall element having a concrete base element, with a longitudinal extension, two longitudinal sides, two front sides, and a base. On at least one of the front sides, at least one coupling element is arranged for connecting the barrier wall element to an adjacent barrier wall element. The barrier wall element has a minimum height of 1.5 m measured starting from the base. A projection that protrudes over the central area and runs in the direction of the longitudinal extension is arranged on at least one of the longitudinal sides, via a central area of the base element, set back relative to a foot area of the base element. The coupling element is arranged at least in sections at the height of the projection.
