Title (EN) METHOD AND MEANS FOR BEACH RESTORATION
(FR) METHODE ET MOYENS POUR LA RECONSTITUTION DES PLAGES
Abstract:
(EN) A method and means are provided for stopping erosion of beach areas and restoring the same by wave and wind activated formation of new dunes, by erecting on the beach area an elongate frame and screen structure (18) of lightweight materials and anchoring said structure to the ground. The frame members are arranged and interconnected to form a plurality of tetrahedral units (Fig. 3) which, in turn, are assembled so as to present to incoming waves a zigzag-shaped wall composed of screen sections (Fig. 2) inclined upwards and landwards, whereby to subject the structure to forces tending to press it down towards the ground and thus to retain it in position even before it is buried in accumulating sand masses. The invention includes special means (Figs. 4, 5, 6) for interconnecting the frame members and for anchoring the structure.
(FR) Methode et moyens destines a arreter l"erosion des plages et a les reconstituer par la formation de nouvelles dunes activee par les vagues et le vent, en dressant sur la plage une structure (18) allongee en forme d"ecran, faite de materiaux legers et ancree dans le sol. Les elements de la structure sont disposes et relies entre eux pour former une pluralite de tetraedres (Fig. 3) qui, a leur tour, sont assembles de maniere a presenter aux vagues qui arrivent une paroi en zigzag composee de sections-ecrans (Fig. 2) inclines vers le haut et vers le continent, soumettant ainsi la structure a des forces tendant a la plaquer dans le sol, la maintenant ainsi en place avant d"etre enterree par accumulation du sable, L"invention inclut des moyens speciaux (Figs. 4, 5, 6) pour relier entre eux les elements de la structure et pour son ancrage.
