Abstract

Le problème à résoudre par la présente invention est de réduire davantage le poids d'une installation de stockage/perméation d'eau de pluie afin d'améliorer la résistance aux tremblements de terre et la maniabilité et de réduire les coûts de fabrication et d'installation. La solution selon l'invention porte sur une plaque de séparation (2) pour une installation de stockage/perméation d'eau de pluie, la plaque de séparation comprenant : une plaque de surface (2a) rectangulaire ; un cadre (2b) ayant quatre côtés qui entourent la plaque de surface ; une ouverture hexagonale arrondie (première ouverture) (2c) qui est présente au centre de la plaque de surface ; des bords (2e) de l'ouverture qui s'opposent respectivement aux coins du cadre ; et des nervures (premières nervures) (2g) qui sont chacune interposées entre une paire de côtés (2f) prenant en sandwich le coin. La plaque de séparation peut également comprendre : des secondes nervures (2h) qui sont chacune interposées entre le coin du cadre et la première nervure ; et des deuxièmes ouvertures (2i) qui sont plus petites que la première ouverture et qui sont chacune disposées dans une partie de la plaque de surface entourée par la seconde nervure, le cadre et la première nervure. La plaque de séparation peut en outre comprendre des troisièmes ouvertures (2j) qui sont plus petites que les deuxièmes ouvertures et qui sont chacune disposées dans une partie de la plaque de surface entourée par le cadre, les bords de la première ouverture et les premières nervures.
