Abstract

La présente invention est un élément structurel de construction d'une structure stratifiée de stockage d'eau de pluie qui consiste à empiler verticalement les éléments structurels tout en croisant les éléments structurels à angle droit dans un réservoir de stockage d'eau disposé sous le sol, l'élément structurel permettant un empilement stable et précis pour obtenir ainsi une structure stratifiée de stockage d'eau avec un petit nombre de niveaux, mais une grande capacité de stockage d'eau de pluie. Un élément structurel (1) a une structure dans laquelle des pyramides quadrangulaires tronquées creuses (2), chacune formée par la fourniture d'une plaque de paroi périphérique inclinée (2b) le long de quatre bords d'une plaque de paroi supérieure rectangulaire (2a) sont disposées côte à côte longitudinalement et latéralement avec les extrémités inférieures de celles-ci mutuellement couplées par l'intermédiaire d'une partie de plaque inférieure (3a) ayant une largeur constante, des parties en saillie (4, 4) sont disposées de façon à faire saillie sur les deux extrémités de la plaque de paroi supérieure (2a) pour supporter les extrémités inférieures des deux parties de plaque de paroi inclinées de la pyramide quadrangulaire tronquée (2) de l'élément structurel côté supérieur (1) sur la plaque de paroi supérieure (2a) de l'élément structurel côté inférieur (1), les extrémités inférieures sont verrouillées à des surfaces intérieures opposées des extrémités inférieures des parties en saillie (4, 4) pour saisir une charge à partir d'au-dessus et en outre une partie d'engagement à évidement (5) qui est placée sur les parties en saillie (4, 4) de l'élément structurel (1) disposé sur le côté inférieur pour ainsi empêcher l'élément structurel (1) de se déplacer aléatoirement longitudinalement et latéralement est prévue dans la partie de plaque inférieure (3a).
