Abstract

PROBLEM TO BE SOLVED: To ensure water supply in emergency by arranging a plurality of storage tanks on the ground, the underground, or in water on the lower position than a collection tank collecting rain water or river water, and arranging a plurality of discharge tanks on the lower position than the storage tanks. SOLUTION: Water from a mountain is collected in a collection tank 1 and received in a filter tank 3, the filtered water is stored in respective storage tanks 5 dividedly arranged. Next, water is sent from the storage tanks 5 to respective discharge tanks 9 through flow adjusting valves 11. Water is discharged and supplied from the dipersedly arranged discharge tanks 9 by pressure difference, utilizing height difference against the collection tank 1. Because a plurality of the storage tanks 5 and the discharge tanks are dividedly arranged, it is unnecessary to build a large structure on one place, and the underground or the undersea can be utilized.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a large-scale water storage structure.

[0002]

2. Description of the Related Art A conventional dam water storage structure is constructed on a vast land surface and temporarily stores water and rainwater flowing from a river.

[0003]

The water storage structure by such a dam has a problem that a large amount of debris flowing from a rapid river accumulates in a short time and the original storage amount cannot be maintained. Has a problem that requires a very large area. In addition, since electricity is used for discharging and feeding water, it is impossible to supply water during a power outage. Especially in the event of an emergency such as a natural disaster such as an earthquake, the water supply is cut off and drinking water and household water are used. However, there is a problem that it becomes impossible to use water for fire extinguishing activities and causes great social confusion.

[0004]

Therefore, according to the present invention, a plurality of storage tanks are arranged on the ground, in the ground or in the water (under the sea) below the collection tank for collecting rainwater and river water. It is characterized by arranging multiple discharge tanks on the ground, in the ground, or in the water (in the sea).

According to such a configuration, the water collected from the mountains in the collection tank is divided and stored in each storage tank,
The water in this storage tank can be sent to each discharge tank, and the water in this discharge tank can be supplied by the pressure generated by the height difference.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram. In the figure,
1 is a collection tank, which is installed in highlands such as mountains. This collecting tank 1 has a structure in which the uncut surrounding surface is covered with a net for rockfall prevention, and the lower part is covered with a waterproof material, or a waterproof lining made of concrete or iron with an elastic film material such as rubber or synthetic resin inside The structure is provided, and the filtration membrane 2 is provided inside if necessary.

Reference numeral 3 denotes a filtration tank, which is provided as needed, and is provided at one location below the collection tank 1 or at a plurality of locations as required. This filtration tank 3 also
It is made of concrete or iron and has a waterproof lining made of an elastic membrane material such as rubber or synthetic resin on the inside, and has a filtration membrane 4 inside if necessary. 5 is a storage tank,
Plural locations are arranged on the ground, in the ground, or in the water (in the sea) so as to be subordinate to the filtration tank 3. As shown in FIGS. 2 and 3, the storage tank 5 has a structure in which a bag body 7 made of an elastic membrane material is provided inside a divided reaction wall 6 made of a rigid body such as concrete or iron. .

The elastic membrane material of the bag body 7 is, for example, a sheet of rubber or synthetic resin, and a cloth made of natural fiber, synthetic fiber, metal fiber or the like, a metal plate or the like is contained in such a sheet. It is preferable to use a material that has elasticity such that it is embedded in a laminated state and has a strong extensibility. When the bag 7 is filled with water and the pressure rises, the bag 7 expands as shown in FIG. 3 and the reaction wall 6 also moves to expand the gap between the divided portions. When a part of the bag body 7 may squeeze out from the gap and burst, a reinforcing material 8 thickened with a material similar to the material reinforced for the bag body 7 or an elastic material or the like corresponding thereto. Is installed at a position corresponding to the gap so that it is wider than the gap.

When placed in water, the same tank as the drain tank described below may be used depending on the conditions. Reference numeral 9 denotes a discharge tank, which is arranged at a plurality of locations on the ground, in the ground, or in water (in the sea) so as to be subordinate to the storage tank 5. It is optimal to be installed in the sea or underwater at a water depth that can receive an external pressure that can withstand the pressure due to the height difference with the collection tank 1, but it may be in the ground.

The discharge tank 9 has the same structure as the storage tank 5 when it is installed in the ground, and has the same pressure resistance as the bag body 7 when it is arranged in water (in the sea). A bag 7 made of a flexible film material is preferable. As shown in FIG. 4, the discharge tank 9 is installed under a rubber or the like if the external pressure Pa acting on the tank due to the water depth and the internal pressure Pb caused by the height difference between the collecting tank 1 are almost equal. A watertight sheet made of a synthetic resin alone may be used.

By disposing the discharge tank 9 in this manner, it is impossible to store water having a pressure higher than that generated by the difference in height, and the discharge tank 9 is always pressed from the storage tank 5. In the figure, 10 is a filtering device provided as needed, 11 is a flow rate adjusting valve provided in the middle of the pipe, and 12 is a turbine for power generation provided as needed, which enables hydraulic power generation.

According to this embodiment having the above construction, the water from the mountains is collected by the collection tank 1 and stored in the filtration tank 3. The water filtered here is stored in each of the storage tanks 4 arranged in a divided manner. The water in this storage tank 5 is sent to each discharge tank 9 through the flow rate adjusting valve 11, and the water in this discharge tank 9 can be supplied to the customer by the pressure generated by the height difference without providing a special water supply device. You can

[0013]

According to the present invention described in detail above, the discharge tanks distributed by utilizing the height difference from the collecting tank have the effect that they can be discharged and supplied from the discharge tank due to the pressure difference. In addition, because the storage tank and the discharge tank can be divided and arranged in multiple parts, it is not necessary to build a large structure in one place like a dam, and since it is possible to use underground or undersea. In addition, it has the effect of not requiring a vast storage area on the ground.

Further, since the respective tanks can be dispersedly arranged and the size of the tank can be made to correspond to the arranging place, there is an effect that the arranging place can be easily selected. In addition, it is possible to secure a stable amount of water for a long period of time without causing the lake bottom to rise due to the accumulation of debris like a dam and the amount of water storage decreasing from the initial amount.
