摘要

The drainage shaft (10) for lateral water removal from surfaces, particularly roads and parking areas, has on at least one side (16) turned away from the surface an edge limitation (18) extending upwards over the drainage surface, which with the shaft forms a firmly connected structural unit. The edge limitation is of one-piece construction with the drainage shaft and is made of concrete. The edge limitation evolves stagelessly into an adjacent edge block (6) of the road limitation. Between the drainage shaft and the surface a water feed channel (3) is provided at the level of the drainage surface (11).
