The structure (1) has two individual bars (2a, 2b) arranged in parallel to each other, connected with each other and extending over an entire length of the structure. The connected bars include a checkered structure. The bars are arranged vertical or in an angle of 0 degrees to 30 degrees to a vertical plane in a mounted condition of the structure. The bars have a uniform wall thickness, and are designed as non-combined adjacent pipes e.g. spiral welded-steel pipes. Foot elements (8a-8d) are arranged at bottom-side closures (6a-6d). The bars are partially coated with a plastic coating. |
