<p>The invention concerns a wall element, in particular steps, panel or the like, forming part of a sunken swimming pool comprising upper and/or reinforced concrete belts. Said wall element is shaped by rotational casting into a double wall, respectively inner (2) and outer (4), which are braced by supporting projections (6, 8) from the inner wall (2) against the outer wall (4), the outer wall (4) comprising on its external surface a member (18) for receiving an anchoring concrete pillar of the element into the concrete belts bordering the pool, such that the outer wall (4) itself comprises support means countering the thrust exerted by the inner wall (2), means which further constitute anchoring means for the element in the belts.</p> |
