Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water storage tank for storing and storing river water for use other than drinking such as fire prevention, watering, or agricultural water.
[0002]
[Prior art]
It has often been practiced to use river water as fire protection water, water for spraying or water for agriculture. However, it seems that river water is stored only for agricultural use. And as a technique for storing river water as agricultural water, simply making a reservoir and introducing river water into it is merely being carried out.
[0003]
Since these reservoirs merely store river water, there is a problem that in the case of drought when the flow of the river is reduced, it is often dried up at the same time and disappears in an emergency.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to solve the above problems, to provide a water storage tank that reliably stores river water while maintaining its quality in good quality, and does not easily lose water even during drought. It is what.
[0005]
[Means for Solving the Problems]
The gist of the configuration of the present invention is as follows.
The bottom of the river is dug down to form a tank recess, and the bottom and peripheral side surfaces of the tank recess are covered with water shielding means to create a tank space inside, and a plurality of unit skeletons are formed in the tank space. It is a water storage tank in which a member is filled to form a space holding skeleton, and the upper portion of the space holding skeleton is covered with a covering material in a water-permeable state, thereby solving the above problem.
[0006]
The tank recess is appropriately rectangular in the length direction when viewed from the plane, but it is not necessary to specifically limit the shape.
For example, when a considerably long tank recess is dug down along the river flow direction, the bottom surface and the peripheral side surface are covered with water shielding means to create a long tank space along the river flow direction. It is appropriate to divide the tank space into a plurality of compartments by water shielding means so as to be shortened in the length direction.
[0007]
Various means can be adopted as the water shielding means, but a rubber sheet is simple and suitable.
The unit skeleton member is not limited to a specific one as long as it is suitable for constituting the space holding skeleton. For example, it can be configured as a bowl-shaped member having connecting means in the front and rear, right and left and up and down directions.
In addition, as the covering material, for example, a mixture of straw, coconut shell charcoal and gravel can be used. However, it is not necessary to limit to this, and only gravel can be used. In other words, any member can be used as long as it can circulate water between the tank space and the river in a covered state but does not allow sunlight to enter the tank space. good.
[0008]
Since this invention is such a structure, when river water is enough, it will flow in the space for tanks through covering materials, such as gravel, and this will be stored. Since the river water stored in the tank space is shielded from sunlight by the covering material, it does not easily rot and remains in a good state.
In addition, even when the river water is reduced or disappears due to continuous sunshine, the river water can be stored until then since it is configured below the bottom of the river. Therefore, it can be used effectively as fire prevention water and agricultural water even in drought when the rivers are withered.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 to 4 show an embodiment of the present invention.
FIG. 1 is a schematic cross-sectional explanatory view showing an embodiment, FIG. 2 is a plan explanatory view in a state in which the upper covering material is omitted, FIG. 3 is a partially cutaway front view of a bowl-shaped member that is a unit skeleton member, and FIG. [FIG. 4] is a side cross-sectional explanatory view showing a state in which hook-shaped members that are unit skeleton members are joined together.
[0010]
First, based on FIG. 3, the bowl-shaped member 1 which is a unit frame member used in this embodiment will be described.
The bowl-shaped member 1 includes a container part 2, a vertical coupling plate part 3 extending outwardly from the upper opening end in parallel with the bottom plate, and a front / rear left / right coupling plate hanging from the outer end of the vertical coupling plate part 3. 4, the bottom plate of the container unit 2, the upper / lower coupling plate unit 3, and the front / rear / left / right coupling plate unit 4 are coupled to each other by bolts and nuts adjacent to each other in the front / rear / right / left direction Bolt holes 5 are formed.
In addition, this bowl-shaped member 1 has through holes 6, 6... Of various sizes and shapes in the container portion 2 and the front / rear and left / right coupling plate portions 4.
[0011]
In this embodiment, as shown in FIG. 1, a bottom 22 of the river 21 is dug down to form a tank recess 23, and a rubber sheet 24 which is a water shielding means along the bottom surface and peripheral side surface of the tank recess 23. Arrange. As shown in FIG. 2, in this embodiment, the tank recess 23 is long along the flow direction of the river 21. Therefore, the tank recess 23 is divided into three sections, and a rubber sheet 24 is arranged at the boundary. , Block the flow of water between each compartment.
[0012]
As shown in FIG. 4, each of the three compartment tank spaces 25, 25, 25 generated by arranging the rubber sheet 24 in the tank recess 23 is provided with the flange members 1, 1,. The space holding skeleton 26 is configured by being coupled to the left and right and up and down to be filled.
In addition to this, gravel or the like in which the coconut shell charcoal as the covering material 27 is mixed is filled in the container portion 2 of the uppermost bowl-shaped members 1, 1. Also add some gravel on top of it.
In this way, a water storage tank for storing river water in a high quality state for the dry season can be completed.
[0013]
In this embodiment, since it is configured as described above, the river water flows into the tank spaces 25, 25, 25 through the covering material 27 such as gravel and is stored when the river water sufficiently flows through the river 21. Will be. The river water stored in the tank spaces 25, 25, 25 is covered with the covering material 27 so that the sun rays are blocked. Therefore, even if new water does not flow in during the drought period, it easily decays. Etc. do not occur and is maintained in a good state.
In addition, since the water storage tank is configured below the bottom of the river even when the river water decreases or disappears due to continuous sunshine, the river water can be stored until then. Therefore, it can be used effectively as fire prevention water and agricultural water even in drought when the rivers are withered.
The storage water can be pumped out by a pump device etc. [0014]
【The invention's effect】
Therefore, according to the present invention, river water can be reliably stored in a good quality state without causing rot or the like due to the drought period. Since the structure is simple, it can be built inexpensively. Moreover, since it is configured in the river, there is no need for new land, and the land of the river is effectively used.
By storing the river water by dividing the tank recess into a plurality of parts, there is an advantage that even if any of the water shielding means is damaged, all the water is not lost. .
