Abstract

The manhole cover (1) has a base surface (2) with frame (3) filled with a cast material (4). The corners (5) of the cover are of plastic and have projections (6), which project over the outer edge of the frame. When the cover is in place, the plastic corner projections only touch the inner edge (7) of the shaft opening, and the projections of neighboring corners. The cover has a ventilation grid (8) of plastic. Corners and grids of a high-strength fiber-reinforced material, and all metal parts of the cover are of corrosion-proof material, esp. stainless steel.
