Abstract

A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13′; 14, 14′; 23, 23′) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12′) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13′; 14, 14′) are provided on the drainage body.
