20080226394 | Leaching chamber having a diagonally ribbed top - A leaching chamber having opposing inwardly and upwardly running sidewalls extending toward a top portion is provided, wherein the leaching chamber includes a plurality of peak and valley corrugations formed by the sidewalls and extending over the top portion and a plurality of diagonally opposed ribs, the plurality of ribs extending diagonally across at least a portion of the top portion to form at least one X shaped pattern. | 09-18-2008 |
20090067929 | Leaching chamber with continuous curve arch and closely spaced corrugations - A method for treating wastewater in a leaching field comprises forming and burying in soil a continuous curve arch shape cross section injection molded thermoplastic leaching chamber. The chamber has inwardly curving sidewalls perforated with closely spaced horizontal slots and peak corrugations which are closely spaced apart on about 8 inch center-to-center distance or less. The chamber configuration in combination with certain plastic material properties and thickness provide strength sufficient to meet regulatory requirements when the soil above the buried chamber is subjected to load. | 03-12-2009 |
20090220302 | PLASTIC DETENTION CHAMBER FOR STORMWATER RUNOFF AND RELATED SYSTEM AND METHODS - A plastic, corrugated open bottom chamber includes features such as one or more of (i) sub-corrugation features on corrugation crests and/or corrugation valleys, (ii) stiffening fingers on the bottom of chamber foot portions, (iii) a viewport configuration that intersects only a single corrugation crest and (iv) a unitary end wall. A method of producing chambers with or without a unitary end wall using a common mold tool is also provided. A method of interconnecting chambers to form a chamber rows is also provided. | 09-03-2009 |
20100284744 | Watering Device, Method for Manufacturing Said Device, and Means Therefor - The invention relates to a device for watering purposes, a proceeding for the manufacture thereof as well as means for the manufacture thereof. The device ( | 11-11-2010 |
20100329787 | Corrugated Leaching Chamber with Hollow Pillar Supports - A plastic leaching chamber has an arch shape cross section, corrugations, and one or more hollow pillars extending downwardly within the interior of the chamber, to support the top of the chamber when the chamber is under load during use. Chambers nest within one another to form a stack of chambers for transport or storage. Chambers have peak corrugations which are substantially wider than the intervening valley corrugations. Chambers having different widths and profiles have common size connectors. | 12-30-2010 |
20100329788 | Corrugated leaching chamber having wide peak corrugations - A plastic leaching chamber having an arch shape cross section and corrugations running transverse to the chamber length has peak corrugations which are substantially wider than the intervening valley corrugations. One or more hollow pillars extend downwardly within the interior of some chamber embodiments, to support the load applied to the chamber. Chambers nest together to form a stack of chambers for transport or storage. Chambers having different widths and vertical profiles have common size connectors for interconnecting as chamber strings. | 12-30-2010 |
20100329789 | Leaching chamber family with common end connectors - In a family of plastic leaching chambers, each having an arch shape cross section and corrugations, there are chambers of different top heights and possibly different widths. Each chamber has a common size of end connector, so chambers within the family, of any size, can be interconnected. Preferably, the height of an end connector is no more than the top height of the smallest chamber in the family. Preferred chambers have one or more hollow pillars extending downwardly within the interior of the chamber; and preferred chambers have peak corrugations which are substantially wider than the intervening valley corrugations. | 12-30-2010 |
20110020065 | Leaching chamber having pillars and wide peak corrugations - A plastic leaching chamber has an arch shape cross section, corrugations, and one or more hollow pillars extending downwardly within the interior of the chamber, to support the top of the chamber when the chamber is under load during use. Chambers nest within one another to form a stack of chambers for transport or storage. Chambers have peak corrugations which are substantially wider than the intervening valley corrugations. Chambers having different widths and profiles have common size connectors. | 01-27-2011 |
20110150574 | ENVIRONMENTAL CULVERT SYSTEM - This invention relates to a novel environmentally compatible culvert system. More particularly, this invention relates to a novel multi-component modular environmental culvert system which is constructed of reaction injection molded components, comprising modular interconnecting bases, modular interconnecting corrugated arch systems, and modular joining binders. A modular culvert system comprising: (a) at least one base grid module; (b) at least one corrugated arch module resting on the grid; and (c) an arch shaped binder module adjacent the arch module. | 06-23-2011 |
20110293371 | Leaching chamber having pillars - A plastic leaching chamber has an arch shape cross section, corrugations, and one or more hollow pillars extending downwardly within the interior of the chamber, to support the top of the chamber when the chamber is under load during use. Chambers nest within one another to form a stack of chambers for transport or storage. Chambers have peak corrugations which are substantially wider than the intervening valley corrugations. Chambers having different widths and profiles have common size connectors. | 12-01-2011 |
20160083921 | CORRUGATED STORMWATER CHAMBER HAVING SUB-CORRUGATIONS - A chamber is disclosed. The chamber may include a base, a plurality of alternating crest corrugations and valley corrugations running transverse to a length of the chamber, wherein the crest corrugations decrease in width with elevation from the base, and the valley corrugations increase in width with elevation from the base, at least one crest sub-corrugation running along at least a portion of a crest corrugation, at least one valley sub-corrugation running along at least a portion of a valley corrugation an end crest corrugation positioned at a terminal end of the chamber, and an end crest sub-corrugation running along at least a portion of the end crest corrugation. | 03-24-2016 |
