Abstract: An installation for the temporary storage of bulk good, such as a composting tunnel, comprises a number of supported floor plates (1), which are slidable in their longitudinal direction, for receiving the bulk goods, the floor plates (1) are jointly movable from their rest position in order to discharge the bulk goods, whereas some of the number of floor plates (1) are individually movable back to the rest position, in which case the bulk good are prevented from moving back by the other plates which, in each case, are not moving. In connection with bringing the floor plates (1) into motion, a separate drive means (3) is provided which comprise a frame (13) with a base consisting of a number of base plates (14), each of which can be coupled to an opposite associated floor plate (1). The base plates (14) are each slidable in the frame (13) in their longitudinal direction and at least a few subsets of the plates are drivable by their own drive installation (17).
