  • square shafts are installed in which installations or connected to which pipes, for a variety of purposes in wastewater, rainwater harvesting systems or the like. Used.
  • a square shaft which serves as inlet, throttle, inspection or filter shaft, and is space-saving because of the square shape incorporated into the respective system, e.g. on an outside or inside of the system.
  • several such square shafts may be stacked.
  • the shaft is closed at the lower open end by a bottom plate, a cover is installed at the upper open end, for example, leads from the at least one attachment part to the ground level.
  • access to the interior of the system is possible.
