摘要： A plastic leaching chamber is provided and includes a chamber substrate constructed from a PET material and having opposing side base flanges which lie in a horizontal plane and extend lengthwise along the chamber substrate. The chamber substrate includes opposing sidewalls extending upwardly from each of the opposing side base flanges to a top of the chamber substrate and includes a lengthwise center plane which is perpendicular to the horizontal plane. The opposing sidewalls define a plurality of leaching openings having at least one tab slot opening located proximate thereto, and a plurality of louver articles constructed from at least one of a PE and a PP material. Each of the louver articles include a tab which is configured to engage a tab slot opening to securely associate the plurality of louver articles with the chamber substrate to cover the at least one leach opening.

摘要： A plastic chamber for collecting, receiving, detaining, or dispersing water when buried is provided and includes a support pillar having at least one pillar wall which defines a pillar cavity. Additionally, the chamber includes a plurality of chamber ends, a plurality of chamber side walls and a chamber top, wherein the chamber top includes a pillar opening and wherein the chamber defines a chamber internal cavity. It should be appreciated that the support pillar extends downwardly into the chamber internal cavity from the chamber top, wherein the pillar opening is communicated with the pillar cavity. The pillar cover is movably configurable between a first configuration and a second configuration to uncover and cover the least one pillar opening.

摘要： A method of making a molded plastic arch shape cross section stormwater chamber having a corrugated wall comprises molding half chambers which are connected by hinges at a joint at the top of the chamber. The chambers may be compactly stored and transported in splayed out configuration. Later, upward force is applied to the hinge joint location of each chamber, so the half chambers are rotated by force of gravity, whereby a faying surface on each half chamber is urged toward the like surface of the other half chamber. The faying surfaces are then fused to each other, preferably as a result of prior heating or by melting of a fusion weld element that is captured in the space between the faying surfaces.

摘要： A plastic article useful as a riser assembly for a septic tank or as part of another structure is comprised of a multiplicity of identical shape conical wall plastic risers. The risers are attached to each other at joints by tabs which engage rim segments; each end of the riser has alternating tabs and rim segments. A riser assembly wall undulates in the lengthwise direction. The risers nest within each other for shipment or storage.

摘要： A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements are melted by internal heating of metal portions of the elements. Two spaced apart circumferential welds which define an annular space are formed. The pressure within the annular space is changed in a test procedure to verify the integrity of the welds.

摘要： A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. The faying surfaces of the flanges of the top and base have portions in the shape of a hollow truncated cone. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements.

摘要： A method of making a plastic tank suitable for containing water comprises forming a tank base which is partially or fully lined with a plastic layer that is different in character or color from the plastic material of the substrate of the tank base. The tank is alternatively formed by injection molding substrate material around the core of a mold which is partially or fully covered by the liner material, and by injecting liner material into the mold to bond it to the tank base substrate in conjunction with retracting part or all of the core, to provide space in the mold for the liner material.

摘要： A set of three tubular drainage units, each comprised of expanded recycled polystyrene aggregate which is gray in color, is wrapped in film which optionally compresses the drainage units radially and which impedes transmission of infra-red radiation to the aggregate when the drainage units are exposed to sunlight during shipping or storage.
