The invention relates to a method for producing a concrete shaft bottom which comprises a drain having a defined shape. According to said method, concrete is introduced into a bottom mold (1) that comprises a mold jacket (2) and a mold bottom (3). On said mold bottom (3), a molded body (8) forming the negative shape of the drain is disposed to configure the drain. The aim of the invention is to allow for the inexpensive and mechanized production of a shaft bottom having an individual drain. For this purpose, the molded body (8) is configured from at least one molded piece (9) that is fixed on the bottom mold (1), especially on the mold bottom (3). The molded piece (9) is adapted to the dimensions of the defined shape of the drain and is removed from the shaft bottom once or while the formwork is dismantled from the shaft bottom. |
