Bodenkonstruktion eines Kompostierungstunnels und Verfahren zu ihrer Herstellung

摘要

The invention concerns a floor construction for a composting tunnel, which includes main air ducts (11) set inside cast concrete, from which distribution air ducts (12) extend to the floor surface. According to the invention in question, the floor (1) is formed of prefabricated hollow-core slabs (5) that are as such known, the hollow cores (11) of which form the aforesaid main air ducts inside the floor. The invention also concerns a method for manufacturing the floor construction of a composting tunnel, in which method prefabricated units are used in the floor construction and in which the pipe networks and ducts are formed in the floor construction for feeding air to the material on the floor. According to the invention, hollow-core slabs (5) are used as the prefabricated units, the hollow cores (11) of which form the aforesaid main air ducts and at the aforesaid hollow cores (11) holes (18) are formed downwards. Finally a surface screed (9) is cast using casting supports (13) set in the aforesaid holes (18).
