摘要

Diving bell to be used when working in the wave affecting zone at one in water standing cylindrical element like a leg (2) of a drilling platform or a bridge pillar, consisting of two or more connected or separate parts (1, 3) which can be brought together in a watertight and locked position round the cylindrical element. In the bell there is a cut out (6) to fit it in a watertight and lockable manner to the surface of the cylindrical element (2). The bottom of the bell is completely or partly open, and there is a pneumatic means to supply the inside of the bell with compressed air to force the water therein. With this construction the produced waste is not collected inside the bell, where the space is restricted, as it is allowed to fall down out of the bell.
