Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water storage tank for storing and storing rainwater or tap water for use in fire prevention or watering.
[0002]
[Prior art]
As fire prevention tanks for storing fire prevention water, those made of concrete or the like installed on the ground or underground are known. Some of these are stored with tap water and others are stored with rainwater. Similar wooden tanks are also known, but these are limited to small ones.
[0003]
These fire prevention tanks are made of concrete, metal, or plate material, so they may be damaged in part due to shaking caused by large earthquakes, etc. If such damage occurs easily, there is a problem that the stored water flows out from the damaged portion and the storage of fire protection water or the like cannot be continued. Therefore, in the case of a fire or the like caused by an earthquake, there is a possibility that a serious trouble that the water for fire prevention cannot be used occurs.
[0004]
[Problems to be solved by the invention]
In the present invention, the above-described problems of fire prevention tanks are solved, and even if a part or all of the peripheral wall is damaged by a strong earthquake or the like, a storage space for water such as fire prevention water is secured, In addition, it is an object of the present invention to provide a water storage tank that can prevent the outflow of water in the storage space.
[0005]
[Means for Solving the Problems]
The present invention comprises a deformable non-permeable lining layer on at least an inner bottom and an inner peripheral side of a tank space partially having an opening, and a plurality of unit skeletons in the non-permeable lining layer This is a water storage tank filled with a member to constitute a space holding skeleton.
[0006]
Therefore, if this water storage tank is filled with rain water or tap water, etc. and stored, even if the peripheral wall is damaged by a strong earthquake, etc., the unit skeleton member is completely broken and crushed. As a result, the water storage space is held by the space holding skeleton constituted by this, and the water-impermeable lining layer is deformable, and even if the peripheral wall is broken, a hole is opened in this. Therefore, the rain water or tap water is always kept securely and can be used effectively as fire extinguishing water for such a fire.
[0007]
The size of the tank space is determined in consideration of the necessity of an area where the tank space is used as fire prevention water or water for spraying. In addition, the underground area is suitable for the area constituting the tank space, but the area formed by digging this space does not have to be a specific place. It is not inconvenient anywhere in a private home garden, park, field, playground, etc. It is not inconvenient even if the area is slightly raised by embankment.
Instead of a new configuration, an existing fire prevention tank may be used as the tank space. In this case, the existing fire prevention tank can be constructed so as not to lose the water storage capability even if damage such as cracking occurs due to an earthquake or the like.
[0008]
The opening of the tank space is provided with a pumping means that extends into the water-impermeable lining layer and can pump water stored in the water-impermeable lining layer. be able to.
This pumping means is not limited to a specific one as long as the water stored inside the non-permeable lining layer can be pumped out as necessary for fire prevention or the like. Manual or electric pumping means can be used, but in order to actually work effectively, such as fire prevention, an electric or other motor-equipped pump with an appropriate capacity would be appropriate. . Considering the response when the power supply or fuel is lost at the time of a disaster, it is appropriate to provide a manual pump means.
When configured in this way, it becomes easy to pump out water for fire prevention or for sprinkling or other needs.
[0009]
The water-impermeable lining layer can be formed by lining a rubber sheet on the inner bottom and inner peripheral side of the tank space. In this case, the rubber sheet is not only deformable but also elastic. Therefore, even when the tank space is damaged, it is easier to maintain the water-impermeable property.
[0010]
The unit skeleton member is not limited to a specific one as long as it can constitute a space holding skeleton by stacking, arranging, or combining a number of the unit skeleton members.
For example, a saddle-like member is configured as the unit skeleton member, and a plurality of the saddle-like members are continuously arranged in the vertical direction and the vertical and horizontal direction in the space inside the water-impermeable lining layer of the tank space. A space holding skeleton can also be constructed.
[0011]
Since this unit skeleton member has such a configuration, it can easily form a space-holding skeleton that is easily coupled to each other, has a high space ratio, is strong, and can easily move water.
[0012]
The unit skeleton member may also be configured as a quadrilateral frame. In this case, a plurality of the quadrilateral frames are arranged in the vertical direction and in the space inside the water-impermeable lining layer of the tank space. A space holding skeleton can be formed by connecting in the vertical and horizontal directions.
In this case, the space ratio can be further increased as compared with the unit skeleton member formed in the bowl-shaped member.
[0013]
In addition, as the unit skeleton member, a small piece member such as gravel can be used in some cases. In this case, whatever the internal shape of the tank space is, it can be freely configured and can be configured simply by putting a required amount into a predetermined part, so that it can be configured very easily and inexpensively. Is.
