A subsurface drainage system (20) for promoting efficient and controlled subsurface drainage of fluids. A drain core (22) is provided that provides rapid infiltration and later movement of subsurface fluids, but which is resistant to settling, compacting and crushing. The drain core (22) is a thermoplastic mat having crush-resistant support members integrated with and upon a backing grid which holds the support members in spaced relation to one another. Fluid flowing into and through the drain core is collected and stored in a fluid storage container (40). The fluid storage container is adapted to be buried beneath the ground, and has an easily assembled internal support structure composed of vertically layered thermoplastic mats. The mats permit fluids to flow freely within the container, and yet lend vertical and structural stability to the container.
L'invention concerne un système de drainage souterrain (20) destiné à favoriser un drainage souterrain de fluides efficace et contrôlé. Un corps de drainage (22) permet l'infiltration rapide et le mouvement ultérieur des fluides souterrains mais résiste au tassement, au compactage et l'écrasage. Ce corps de drainage (22) est constitué d'un mat thermoplastique possédant des éléments de support résistant à l'écrasage et intégrés avec et sur une grille d'armature qui maintient les éléments de support espacés les uns des autres. Le fluide s'écoulant dans et à travers le corps de drainage est collecté et stocké dans un récipient de stockage de fluides (40). Ce récipient de stockage de fluides est conçu pour être enterré et possède une structure de support interne assemblée aisément et composée de mats thermoplastiques stratifiés verticalement. Ces mats permettent le libre écoulement des fluides au sein du récipient tout en lui conférant une stabilité verticale et structurale.
