rigolenanordnung with rigole and shaft

摘要

rigolenanordnung with an underground rigole (20, 120) which by means of a rigolenwandung (20a; 120a) is limited, the temporary retention of fluid, and with at least one shaft (16a, 116a) is limited and the rigole (20, 120) is connected, thereby gekennzeichne t that the shaft (16a, 116a.150a) and the rigolenwandung (20a; 120a) along a beru00fchrlinie (20a2; 120a2, 150a2) touch, with the shaft (16, 116, 150) on the rigole (20, 120) is arranged such that a normal projection (30a; 130a) of the beru00fchrlinie (120a, 20a2;150a2) in a schwerkraftwirkungsrichtung (g) orthogonal level (e) within a normal projection (28, 128) of the rigole (20, 120) in the level (e) and the shaft (16, 116, 150) completely in the schwerkraftwirkungsrichtung (g) on the rigole (20, 120 the erdra) (a) is arranged.
