【産業上の利用分野】本発明は、地下に埋設される防火
用の水槽に関する。更に詳しく述べると、漏水防止用の
内張りが設けられた防火水槽に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank for fire protection buried underground. More specifically, it relates to a fireproof water tank provided with a lining for preventing water leakage.
【０００２】[0002]
【従来の技術】防火水槽は、例えばコンクリートから成
形され、地下に埋設されている。この場合、水槽に収容
された水がコンクリートの壁を透過して地中に滲みだす
ことを防止しなければならない。そのため、従来、水槽
のコンクリートの内面にエポキシ樹脂をコーティング処
理して、漏水防止膜を形成している。2. Description of the Related Art A fire protection water tank is molded from concrete, for example, and is buried underground. In this case, it is necessary to prevent the water contained in the water tank from permeating through the concrete wall and seeping into the ground. Therefore, conventionally, the inner surface of the concrete of the water tank is coated with an epoxy resin to form a water leakage prevention film.
【０００３】[0003]
【発明が解決しようとする課題】しかしながら、このエ
ポキシ樹脂をコーティングした漏水防止膜によると、次
のような問題があった。However, the water leakage prevention film coated with the epoxy resin has the following problems.
【０００４】地震などが起きた場合、漏水防止機能を損
なうおそれがあった。すなわち、地震により、水槽のコ
ンクリートに亀裂が入ったり、コンクリートブロックど
うしの継ぎ目にズレが生じると、水槽内の水が漏れるこ
とが避けられなかった。When an earthquake or the like occurs, there is a risk that the water leakage prevention function will be impaired. That is, if the concrete in the water tank is cracked or the joint between the concrete blocks is displaced due to the earthquake, it is unavoidable that the water in the water tank leaks.
【０００５】また、膜を形成するため樹脂をコーティン
グする作業が大変であった。すなわち、吹き付け機器に
よりコーティング作業をしなければならず、施工コスト

造を形成しなければならず、この点においても高コスト
となってしまう。Further, the work of coating the resin to form a film has been difficult. That is, the coating work must be performed with a spraying device, and the construction cost is high. Further, in the case of constructing the water tank by joining the concrete blocks together, it is necessary to form a seal structure at the joint, which also results in high cost.
【０００６】また、地震などによりエポキシ樹脂の膜が
一部剥離して漏水を招いた場合、水槽内の水をいったん

トであった。If the epoxy resin film is partly peeled off due to an earthquake or the like and water leaks, the water in the water tank is once extracted, and then a person enters the water tank through the pumping port to perform coating work again. It also had to be expensive.
【０００７】さらに、コンクリ−トブロックそのもの
や、エポキシ樹脂の中には、人に対して毒性の強い部分
を含むものがあるので、飲用に供することができない。
したがって、地震などの非常時に、防火水槽の水をその
まま飲用できないという問題があった。Further, some of the concrete blocks themselves and the epoxy resin contain a portion which is highly toxic to humans, and therefore cannot be used for drinking.
Therefore, in an emergency such as an earthquake, the water in the fire protection tank cannot be drunk as it is.

内張り２が形成される。The lining of this example is mounted on the inner surface of the water tank by inflating the bag 2 (the lining 2 and the bag 2 are the same member) inside the water tank as follows. After applying an adhesive to an appropriate place on the inner surface of the water tank in advance, put one bag 2 made of a soft resin sheet inside the water tank, and put the mouth of this bag 2A at the outlet 4 Position it. Next, compressed air from a compressor or an air cylinder (not shown) is injected from the mouth of the bag 2A to inflate it and the inflated bag 2
The outer surface of is pressed against the inner surface of the water tank to bond the bag 2 and the inner surface of the water tank. As a result, the lining 2 conforming to the shape of the inner surface of the water tank is formed.

In particular, when the base material made of high-strength yarn such as Tetron (registered trademark of Toray Industries, Inc.) and the material made of vinyl chloride integrated with the base cloth are used as the material of the sheet, strength and hygiene are improved. It will be excellent in both respects.
【００４６】以上のように構成された防火水槽による
と、次のように地震時などに優れた漏水防止性を発揮す
る。According to the fire protection water tank constructed as described above, the excellent water leakage prevention property is exerted in the case of an earthquake as follows.

支障を生じたり、飲用ができなくなるということを防止
できる。When a large earthquake occurs, the concrete in the water tank may be cracked or the joint between the blocks may be displaced to form a gap. However, since the inner lining 2 made of a flexible soft resin is provided on the inner surface of the water tank, it is possible to flexibly deal with deformations such as cracks and deviations, and to prevent deterioration of water leakage prevention. That is, since water does not leak and mud does not enter the water tank, it is possible to prevent fire from being hindered and preventing drinking.
【００４８】特に、この例では、内張り２が一枚の袋か
