Abstract
A rectanguloid shape six-walled thermoplastic box for receiving and dispersing stormwater, when part of an array of like boxes that is buried in media, has interior bracing in the form of an irregular polyhedron structure comprised of up to six hollow pyramids. The truncated apexes of the pyramids meet near the center of the box. The base of each hollow pyramid is contact with, attached to, or integral with a wall at the location of an opening within which is a grate. A box may be injection molded as a single piece molding with living hinges. Alternatively, the pyramidal polyhedron structure may be formed as a separate element and placed within the walls of a box.
Claims20
A box, made of thermoplastic and useful for receiving and dispersing liquid when buried in permeable media, the box having a rectanguloid shape, comprising:
- six walls, attached to each other thereby forming said rectanguloid shape, each wall having an interior surface, an exterior surface, and one or more passageways through the wall;
- wherein one or more of the walls further comprises a plurality of T-shaped cavities in the exterior surface of the one or more walls, the plurality of cavities being configured to receive a portion of a T-shaped connector;
- and
- a bracing structure having an irregular polyhedron shape, the bracing structure comprising first, second, third, fourth, fifth, and sixth hollow pyramids, each pyramid having a base, a length, and a truncated apex;
- the base of each pyramid being in contact with, attached to, or integral with, a wall of the six walls;
- wherein a portion of each pyramid is in mating contact with, attached to, or integral with, a portion of one or more other pyramids.
A box for receiving and dispersing liquid when buried in permeable media, the box having a rectanguloid shape, comprising:
- six walls, attached to each other to form said rectanguloid shape, each wall having an interior surface, an exterior surface, and one or more passageways through the wall;
- wherein one or more of the walls further comprises a plurality of T-shaped cavities in the exterior surface of the one or more walls, the plurality of cavities being configured to receive a portion of a T-shaped connector, and
- a bracing structure comprising an even-number of hollow pyramids, each pyramid having a base, a length, and a truncated apex;
- wherein the base of each pyramid is integral with a wall at the periphery of an opening therein;
- the pyramids being arranged as pairs that lie along the same axis;
- wherein a first pyramid of a first pair of pyramids extends from a first wall and a second pyramid of the first pair of pyramids extends from a second wall, the truncated apex of the first pyramid contacting the truncated apex of the second pyramid;
- and wherein the box further comprises one or more additional pair of pyramids having a first pyramid and a second pyramid configured to contact the first and second pyramids of the first pair of pyramids.
