Rsv-gusto Engineering B.v.

Karel J De Werk

A device for sealing the lower part of a column standing on or in the bottom below a body of water, comprises a plate-shaped body surrounding the column, the plate-shaped body having a flexible border strip that runs around its entire circumference. The plate-shaped body is rigid and is mounted on a rigid sleeve surrounding the column and extending downwardly in the plate, the walls of the sleeve being parallel to the walls of the column. The body and the strip are of an impermeable material. Erosion of the material of the bottom from around the lower part of the column, under the influence of water currents, is thus retarded.
