  • FIG. 12 is only intended to show that the set-up device 22 does not necessarily have a circumferential mounting ring corresponding to the retaining ring 22c shown in FIG. 1, but that it is also possible to have a plurality of support arms to be provided independently of one another normally in vertical axis extending setup axis r can be pivoted and if desired also independently in the direction of the setup axis r, i.e. normally in the vertical direction.
  • bracket arms 22f On the free ends of these bracket arms 22f can be bracket devices for the arrangement of recess cores 20 or their mounting strips 32 may be provided.
  • the main channel 12c and the Secondary channel 12d and, if desired, the rest of the bottom 12a and if necessary, even part of the inner surface of the side wall 12b of the Can be provided with a lining, to protect the concrete from attack by aggressive wastewater.
  • These linings can for example be made of bricks, tiles, tiles or be made of plastic. These linings can also be used prepared the set-up device and by means of this set-up device in the Mold cavity 18 are introduced.
