Problems solved by technology

[0007] However, in the above-mentioned conventional dust removal management well, since the water supplied from the inflow pipe needs to be temporarily stored in the management well, the management well itself is vertically long, and the depth of burying the management well becomes relatively deep, so there is a problem of Disadvantages that are difficult to manage, such as troublesome removal of accumulated dust and dirt inside the management well

Embodiment Construction

[0037] Hereinafter, the best mode for carrying out the present invention will be described based on the drawings.

[0038] Such as figure 1 As shown, the dust removal management well 20 and the water storage tank 10 of this embodiment are connected and installed. The water storage tank 10 is buried in the ground, which means that the water storage tank 10 stores rainwater that falls on the roof or roof terrace or the ground of the house. A drainage unit not shown is used to pump out the water stored in the water. Reuse. figure 1 The water storage tank 10 of the example is formed by covering an assembly formed by combining a plurality of water storage materials 12 with a waterproof sheet 14. As the water storage material 12 of this embodiment, a plastic molded body 12 molded with a metal mold is used. The water storage material 12 composed of the plastic molded body is formed into a truncated pyramid shape, and after being arranged vertically and horizontally, the water storage m...

Abstract

To facilitate cleaning and its management. A pit (20) for managing dust removal comprises a bottomed upper pit (22) connected with an inflow pipe (20a), and a tubular lower vertical pit (23) having aupper portion connected with the upper pit and supplying water trickling from an opening at the upper end to a water storage tank (10). Upper end of the lower vertical pit penetrates the bottom wall (22a) of the upper pit, the circumferential wall (22b) of the upper pit surrounds the upper end of the lower vertical pit and a circumferential groove (33) for precipitating solid matters contained inthe water is formed between the periphery of the upper end and the circumferential wall of the lower vertical pit. A mesh plate (34) for filtering the water arriving at the circumferential wall is provided in the upper pit. One end of a drain pipe (36) having the other end coupled with a sewer pipe is coupled with the circumferential groove and a regulation valve (38) is provided in the drain pipe. The bottom face of the circumferential groove is formed to incline relative to the horizontal surface such that the side coupled with the drain pipe is made lower and water in the circumferential groove flows into the drain pipe, and the inner surface of the circumferential groove is formed to bend or incline such that the inside width of the circumferential wall decreases from the inflow pipe side toward the drain pipe side.

Description

Technical field [0001] The present invention relates to a dust-removal managing pit (dust-removal managing pit) that is installed in connection with a water storage tank, a sewer, etc., which are buried underground to store water, and removes dust and dirt from the water supplied to the water storage tank, the sewer, etc. Background technique [0002] Conventionally, as equipment for effectively using rainwater, there is known an equipment that bury a water storage tank underground and store rainwater in the water storage tank. This equipment is configured to collect rainwater that has fallen on the roof or roof terrace or the ground using a downpipe or a groove (ditch), and introduce the collected water into an inflow pipe, and supply the water to the water storage tank through the inflow pipe And stored in the water storage tank. In addition, such a facility is configured to provide a drainage unit capable of drawing water stored in the interior from the ground, such as a pump...
