Abstract (en)
[origin: WO2017063010A1] The invention relates to a method for producing concrete pipes in a standing casting mold, comprising a molding space (4) between a core and a longitudinally divided casing (3), and molding sleeves (5, 9) closing off the molding space (4) on top and bottom, wherein pourable concrete is filled into the molding space (4), and after a setting of the concrete, the pipe body (7) is demolded by opening the casing (3). In order to be able to cast concrete pipes of high quality, the pourable concrete, according to the invention, filled into the molding space (4) in a predetermined quantity while the top molding sleeve (9) is removed and the top molding sleeve (9) forming a closed ring is shapingly pressed into the end face of the pipe body (7) between the core (2) and the casing (3) only after a setting time for a predetermined setting volume of the cast pipe body (7).
