Shaft bottoms

LEIER shaft bottoms are designed for gravity loads (without overpressure). They can be used as underground cleaning shafts, they are suitable for the construction of sewerage networks in which the transported polluted water, rainwater or ground water does not damage the material of the concrete elements due to its chemical composition, nor does it have an aggressive effect on the connection of the elements. Manhole bottoms for mortar joints are produced with internal diameters of 800 and 1000 mm (AFE-L). We supply the version with a rubber seal only with a diameter of 1000 mm. It is possible to build in inserts for Smooth, Corrugated and Hobas pipes, which achieves maximum sealing. Manhole bottoms AFE 100/130 and 150/150 allow the connection of pipes with a diameter of DN50, DN 80, DN 100. Manhole bottoms are produced with or without kinematics. Standard shaft bottoms are made with 200, 300 and 400 mm diameters of the kinetotics. The creation of the kinet is controlled according to the complete flow height of the cross-section.
