<p>The invention relates to a covering structure (10) of a flexible device used for covering poured or stacked material (12), especially for the aerobic treatment of waste containing organic matter, such as residual waste or garbage, in a rotting pit. The covering structure comprises a tarpaulin that is provided with a number of supporting elements (22) which can be filled wi th at least one fluid and are at least partly interconnected, and at least one waterproof, gas-permeable planar structure (14). Said planar structure (14) is connected to the supporting elements. The inventive device forms an erected and a lowered state depending on whether the supporting elements are filled or not. The planar structure covers the material and is respectively raised and lowered when the supporting elements are filled and emptied.</p> |
