Abstract

L'invention concerne une structure de guidage de sac de sable mise en place sous un sac de sable et permettant d'agencer et de relier une pluralité de sacs de sable. La structure de guidage de sac de sable rectangulaire (10) est formée d'un support plan (11) sur lequel repose un sac de sable (40). Des broches (23a, 23b) d'une pièce de fixation (20) sont insérées, par l'extérieur du sac de sable (40), dans des trous de petit diamètre ménagés dans le support plan (11) et des cliquets (33a, 33b) d'une pièce de raccord (30) sont insérés dans un trou rectangulaire (22) de la pièce de fixation (20) et un trou de liaison (13) du support plan (11), ce qui permet de relier une pluralité de structures de guidage de sac de sable (10) sous la forme d'un treillis. Chaque sac de sable (40) ainsi relié est alors rempli de matériau. L'invention concerne également un procédé de construction par sacs de sable permettant de réduire sensiblement le temps nécessaire à la pose des sacs de sable (40) et particulièrement avantageux du point de vue économique.
