|20130284750||STORAGE COMPOSITE, AND STORAGE TANK AND PERMEABLE STORAGE TANK USING SAME - The interior of a storage tank is filled with a storage composite and one cylindrical rib is positioned on each of the lower surface and the upper surface of partitions to project therefrom. Funnel-shaped end spacers have a large-diameter tube portion for engaging with and connecting to the cylindrical ribs on the upper and lower surfaces of the partitions, and a small-diameter tube portion having a smaller diameter than the large-diameter tube portion. Both ends of cylindrical connecting spacers engages with the small-diameter tube portion of a pair of end spacers, and the length of one side of a partition is S, the diameter of the section in which the cylindrical rib engages the large-diameter tube is set within the range of 0.40S to 0.95S. Multiple levels of horizontal connected units are provided, and end spacers and connecting spacers are interposed between the horizontal connected units of multiple levels.||10-31-2013|
|20120118802||RAINWATER FILTERING DEVICE FOR INFLOW PATH - Collected rainwater is led to a rainwater containing section by an inflow path. A water-permeable tube body extends vertically in the middle of a vertical pipe located immediately before a position at which the rainwater flows into the rainwater containing section. A bag-like filter having an open upper end and a closed lower end is contained in the tube body or covers an outer side of the tube body, and the bag-like filter captures dust in the rainwater while allowing the rainwater to pass through the bag-like filter. A mounting and dismounting means is provided to the vertical tube in order to dismount the tube body and the filter from the vertical pipe and to mount the tube body and the filter to the vertical pipe.||05-17-2012|
|20100116358||DUST-REMOVAL MANAGING PIT - To facilitate cleaning and to facilitate management thereof, a dust-removal managing pit is provided with an upper pit having a bottom and to which an inflow pipe is connected and a cylindrical lower vertical pit having its upper part connected to the upper pit for supplying water flowing down from an upper-end opening portion to a water storage tank. The upper end of the lower vertical pit is provided penetrating a bottom wall of the upper pit, while a peripheral wall of the upper pit is provided so as to surround the upper end of the lower vertical pit, and a peripheral groove for precipitating solid substances contained in water is formed between the periphery of the upper end of the lower vertical pit and the peripheral wall. A mesh plate constituted capable of filtering water leading to the peripheral groove is provided on the upper pit. One end of a drain pipe with the other end connected to a sewer pipe is connected to the peripheral wall, and an adjusting valve is provided in the drain pipe. A bottom face of the peripheral wall is formed with inclination with respect to a horizontal plane by lowering the side to which the drain pipe is connected so that the water in the peripheral groove flows into the drain pipe, and an inner face of the peripheral wall is formed with curvature or inclination so that a width of the inside of the peripheral wall from the inflow pipe side toward the drain pipe side is decreased.||05-13-2010|
