[Industrial application] The present invention is mainly applied to the rooftop greenery ground,
The present invention relates to a water storage / flushing device attached to slope roads, flat grounds, sports grounds, and the like.

[0002]

2. Description of the Related Art The present applicant previously filed Japanese Utility Model Application No. 4-33911.
No. (device name: drainage / water retention device) has been applied for. This drainage / water retention device (hereinafter referred to as wastewater treatment floor material)
Has been proved to be effective as a drainage material for promoting drainage in place of the gravel drainage layer of the greened ground formed on the roof of a building. In addition, this floor material for wastewater treatment is also used as a drainage material for promoting drainage on slope roads, flat grounds, sports grounds, and the like.

[0003]

However, in the former use example, rainwater is drained smoothly by laying the above-mentioned floor material for drainage treatment, while at the time of rainfall, embankment is applied to the upper panel of this floor material for drainage treatment. The soil particles (soil) to be formed become muddy and flow into the inside of the wastewater treatment floor material through a large number of drain holes formed in the upper plate of the wastewater treatment floor material, and this mud is discharged into the wastewater treatment floor material. If the material adheres to the concrete floor surface of the building where it will be placed and is left for a long period of time, it will become muddy soil on the concrete floor surface and will solidify and solidify, impeding the drainage of the rooftop greening ground. There is no denying what to do. Moreover, since various components such as inorganic substances contained in soil particles (soil) are deposited on the concrete floor surface, the concrete components are dissolved over the years, which may cause water leakage in the building. Also, in the latter use example of Baba, by laying the floor material for wastewater treatment,
Although it is possible to improve drainage during rainfall, over the years, the material that forms the upper layer of the floor material for wastewater treatment (for example,
Particles such as soil and wood) and oily components may adhere to and deposit inside the lower floor material for wastewater treatment, thereby impeding the drainage performance of the horse riding ground. Therefore, an object of the present invention is to provide a water storage / flushing device incidental to a rooftop greenery ground, a slope ground, a flat ground, a playground, etc., which can solve the above problems.

A protrusion for joining is formed to project from the joining recess formed on one side of the wall material, and is projected on the other side of the adjacent pipe supporting wall material on the other side of the wall body. And a concave portion for joining that is joined to the convex portion for joining.

[0010]

Since the present invention is constructed in this way, the accumulation of mud on the concrete floor can be eliminated as follows.

When constructing a rooftop greenery ground in a required area of a concrete floor surface, first, a required number of drainage treatment floor material main bodies are provided on the concrete floor surface with connecting convex portions and connecting concave portions which are adjacent to each other. While laying the open side of the floor material for wastewater treatment facing the concrete floor surface while connecting with the section, a water-permeable net is laid on the upper plate of the body of the floor material for wastewater treatment that has been laid. A vegetation soil layer is formed on the upper surface of the net, and greening plants are planted in this vegetation soil layer. (A) Action during rainfall Rainwater that permeates the vegetation soil layer of the above-mentioned rooftop greening ground passes through the water-permeable net and becomes muddy liquid, which is drained from multiple drainage holes in the upper floor of the main body of the wastewater treatment system. Rooftop from the drain hole that flows into the main body of the treatment floor material and connects the frame walls of the main body of the waste water treatment (drain holes formed in the frame wall of each adjacent main body of the waste treatment floor). The muddy water flows out to the concrete floor surface around the greened ground, and together with the surface water stored on the same concrete floor surface, the muddy water naturally flows into the first water tank installed in the drainage hole of the building and is collected. The muddy water collected in the first water tank is separated into water and mud (sludge) by the filtering action of the filter in the first water tank, and the mud collected in the filter can be removed by removing the filter. Be discarded. Rain water that has overflowed in the first water tank is discharged to the outside of the building through the central cylindrical portion in the tank and the building drain hole communicating with this. During heavy rain, when the water level on the concrete floor becomes higher than that of the first water tank, another drain hole is opened and water is discharged through the bypass pipe. When storing water in the first water tank, the other water drain holes and the building water drain hole communicating with the first water tank should be closed.

(B) Washing action If there is a concern that mud or the like will be deposited or solidified on the concrete floor surface on which the above-mentioned main body of the floor material for wastewater treatment is placed, rainwater in the first water tank will The water is automatically sent to the wastewater purifying tank for purification, and the rainwater purified by the wastewater purifying tank is automatically sent to the next second water storage tank. The purified water (or tap water) stored in the second water tank is automatically sent to the next pressurized drain tank, and the required water pressure is secured by the compression pump of this pressurized drain tank. The pressurized water thus pressurized by the pressurized drainage tank is used to hold the pipes for washing water of the pipe support wall material that is attached to the concrete retaining wall on the rooftop of the building located above the gradient of the concrete floor surface that forms the rooftop greenery ground. A plurality of pressurized water jet nozzles, which are installed in the recesses and are supplied under pressure to the washing water conduit that is piped so as to surround the outer circumference of the rooftop greenery ground, and at the same time, are oriented around the outer circumference of the floor material for wastewater treatment of the rooftop greenery ground. The pressurized water which is activated and forcedly jetted from the pressurized water jet nozzle is discharged into the inside of the wastewater treatment flooring material body through a drain hole formed in the frame wall of the wastewater treatment flooring material body facing the pressurized water injection nozzle. Therefore, the concrete floor surface can be washed by the jetting force of the pressurized water. In the present invention, the bottom plate is arranged on the concrete floor, and the projections provided on the upper surface of the bottom plate are fitted into the downward structure columns of the wastewater treatment floor material main body to be integrally assembled. When the above is used as the floor material for wastewater treatment of the rooftop greenery ground, the above action can eliminate the accumulation of mud and the like on the upper surface of the bottom plate.
