Description
Technical Field
The invention discloses an underground rainwater storage tank with a prediction function, and particularly relates to a storage tank which combines a storage function and a permeation function. Furthermore, the invention relates to a technology for supervising the water level inside such a tank.
Background
Most commonly used disaster prevention water systems, such as dams, store rainwater in the event of a heavy rain to prevent downstream areas from being damaged by floods, while generating electricity from water stored inside the dams. Such a large-area dam system can naturally balance the use of inflow and drainage of rainwater according to medium-to-long term rainfall predictions of a facility area. When a storm disaster is expected, the dam may reduce the water level according to the predicted rainfall. Some water storage tanks that store rainwater and use it for irrigation are widely used and can be used as part of disaster prevention systems during building construction for planning. The domestic small-sized water storage tank can store rainwater, and can pump out the stored water according to the need, and can be used for irrigation and the like. However, the household water storage device does not have a function of automatically adjusting the water level of the water tank according to rainfall prediction.
Disclosure of Invention
The object of the present invention is to store water from a water storage tank buried underground so as to ensure a sufficient water storage capacity in advance, thereby storing rainwater even in the case of sudden heavy rain. The goal is to allow water to penetrate into the ground faster.
Another object of the present invention is to more reliably prevent the water storage tank from being lifted up due to an increase in the groundwater level caused by rainfall or the like.
Another object of the present invention is to more easily and effectively construct the water storage device at a lower cost according to installation conditions such as the scale of the water storage capacity, the installation area and the topography.
According to the present invention, a water storage device includes a bottom wall, a peripheral wall, and an upper wall, and is buried in the ground, wherein the bottom wall includes an inner bottom wall surface and an inner bottom wall surface that are impermeable to water. The permeable outer bottom wall surface defines a bottom gap extending across the entire bottom wall, and a switching system disposed on the inner bottom wall surface such that the interior of the water storage tank communicates with the bottom gap. The water permeable outer peripheral wall defines a side gap extending through the entire peripheral wall between the inner peripheral wall surface and the water impermeable inner peripheral wall. And further comprises a transfer means for transferring the water stored in the side gap into the water storage tank.
The bottom wall of the water storage tank is constructed in this way, and water flowing out of the water discharge opening enters the bottom space of the bottom wall, flows through the bottom wall and flows in the horizontal direction, and spreads to the bottom wall and the bottom wall. Thus, a desired amount of stored water can be discharged from the tank into the ground in a shorter time. Furthermore, by transferring the water reservoir in the side gap to the tank, the weight of the tank (including the amount of water reservoir in the water reservoir space) is adjusted so that it always exceeds the buoyancy of the groundwater. It is possible to prevent the water level from rising or the water storage amount from being significantly reduced and the water level from rising. The amount of water stored in the water tank and the free capacity prepared for preventing disasters such as rainfall are appropriately determined according to time conditions, weather changes, and the like.
When a lateral external force caused by an earthquake or the like acts on the water storage tank due to a smooth surface, the protective panel may slide in a horizontal direction with respect to the bottom wall plate. It is thus possible to effectively prevent the peripheral wall panel, the water storage sheet, etc. provided on the protective panel from being damaged or leaking due to external force such as vibration of the bottom wall panel.
According to the present invention, the watertight surface, the water permeable surface facing the watertight surface, and the support portion supporting the watertight surface and the water impermeable surface to define a gap therebetween. The water permeable surface and the water impermeable surface form surfaces respectively connected to the water permeable surface and the water impermeable surface of the other unit panel, and the gap is provided to be continuously installed in a surface direction of the water permeable surface or the water impermeable surface so as to communicate with the gap of the other unit panel.
Drawings
Fig. 1 illustrates a water storage device embedded in the ground according to an embodiment of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a water storage tank 1 is composed of a bottom wall 2, a peripheral wall 3 and an upper wall 4, and has a generally rectangular box-shaped structure defining a predetermined capacity of a water storage space 5 therein. The bottom wall 2 is provided with a drain opening 6 for access to the ground. In the upper wall 4, an upper opening 7 is provided at a position substantially corresponding to an upper portion of the drain opening 6, and is connected to a manhole 8 communicating with the ground. The tank 1 is mounted on a foundation 9, which foundation 9 is distributed over the bottom of the excavated ground. In the present embodiment, the foundation 9 is configured by constructing a large number of packages 10. The bottom wall 2 includes a bottom inner wall portion 11 having a water impermeable surface, a bottom outer wall portion 12 having a water permeable surface, and a support portion 13 supporting them. Between the bottom inner wall portion 11 and the bottom outer wall portion 12, the support portion 13 defines a bottom gap 14, which bottom gap 14 communicates over substantially the entire surface of the bottom wall 2. The bottom gap 14 opens from the periphery of the bottom wall 2 to the outside, i.e. to the ground. Further, the drain opening 6 of the bottom wall 2 opens in the bottom gap 14, so that the bottom gap can communicate with the water storage space 5.
The water permeable surface of the bottom outer wall section 12 is formed by forming a large number of openings communicating with the bottom gap 14 on the outer wall surface of the bottom outer wall section 12, and placing a water permeable sheet on the outer wall surface of the bottom outer wall section so as to cover the openings. When the bottom inner wall portion itself is formed of a water impermeable material. When the material of the bottom inner wall portion 11 does not have complete water impermeability, a water impermeable surface is obtained, for example, by applying a water impermeable sheet or a water impermeable paint to the wall surface of the bottom inner wall portion. The peripheral wall 3 has a pair of left and right side walls 15 and 16 facing each other and two pairs of front and rear side walls facing each other in a direction orthogonal thereto. Therefore, although the surrounding wall of the present embodiment is formed in a rectangular box shape, it may be formed in a polygonal shape other than a rectangle or a circle. Since each of the side walls has the same structure, only the left side wall 15 is shown, and the description of the other side walls is omitted. The left side wall 15 includes a side inner wall portion 17 having a water impermeable surface, a side outer wall portion 18 having a water permeable surface, and a support portion supporting them. Between the side inner wall portion 17 and the side outer wall portion, a side space 19 is defined by the support portion so as to communicate over substantially the entire left side wall 15. The side gap 19 opens to the outside, i.e. to the ground, from both sides of the left side wall 15.
