<p>The submersible construction element is for the building of dykes, jetties, etc. or for the prevention of undesirable wave action. The element consists of sections, which have different weights in water. The sections are positioned and/or formed, so that the element occupies a pre-determined stable position in the water. The element has hollows which are connected to the surrounding water. It may consist of a vehicle tyre (1) with an eccentric body (7) for weighing-down. Alternatively, it may consist of an open or closed barrel, which weighed-down has upper longitudinal slots, and is surrounded by a buoyancy ring.</p> |
