Abstract

A cast-iron and concrete circular manhole with a concrete-filled, trough-shaped shell (1) which merges into a peripheral wall (5) with a bottom bearing surface (7) has a number of air openings designed as elongated holes or slots which are each arranged near the edge and are connected to the peripheral wall (5) by a flange (19) at the top of the manhole, an engagement pocket for a lifting tool which can be inserted through the air openings (17) being formed beneath the flange. <IMAGE>
