Abstract (en)
[origin: US2013059026A1] A method for producing a concrete shaft bottom which comprises a drain having a defined shape. Concrete is introduced into a bottom mold that comprises a mold jacket and a mold bottom. On the mold bottom, a molded body forming the negative shape of the drain is disposed to configure the drain. The invention allows for the inexpensive and mechanized production of a shaft bottom having an individual drain. For this purpose, the molded body is configured from at least one molded piece that is fixed on the bottom mold, especially on the mold bottom. The molded piece 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.
