Abstract

Structure de diffusion d'eaux pluviales, comprenant des éléments de drainage horizontal et de diffusion vertical, tous deux constitués par des éléments annulaires, entourés d'une enveloppe géosynthétique, à indice de perméabilité approprié pour cette fin, lesdits éléments étant collés par procédé de fusion. L'élément de drainage horizontal est constitué par des éléments annulaires de section droite carrée, alors que l'élément de diffusion vertical est constitué par des éléments annulaires de section droite rectangulaire et, de préférence, de section droite en "T", formant ainsi une âme permettant d'obtenir un plus haut degré de résistance aux efforts exercés par les parois du puits sous-vertical sur la périphérie extérieure de l'élément diffuseur vertical.
