の鋼管内の水が漏れ出さずに済む。In the fire protection water tank of the present invention, the bottom is formed in the steel pipe,
The steel pipe is vertically erected and buried in the ground, and the opening of the steel pipe is closed by a lid. This steel pipe has sufficient elasticity as compared with concrete. Therefore, even in the event of an earthquake, the steel pipe is hardly cracked, and the water in the steel pipe does not leak out.

The cost of construction materials and construction can be kept low because it is possible to follow the basic construction of the building. Furthermore, since this steel pipe is vertically erected and buried, the occupied area is only slightly larger than the cross-sectional area of the steel pipe.

The opening edge of the bag 9 made of synthetic resin is sandwiched between the reinforcing ring 6 and the inner lid 7, and the bag 9 made of synthetic resin is loosened in the vicinity of the opening 5 of the steel pipe 1. The bag 9 made of synthetic resin is provided for rust prevention. Further, the bag 9 made of synthetic resin is regularly replaced together with the water in the steel pipe 1 to prevent contamination.
【００１５】さて、この実施例の防火水槽を建造する手
順は、ビルの基礎造りに倣ったものであり、次の通りで
ある。The procedure for constructing the fire protection water tank of this embodiment follows the basic construction of a building and is as follows.
【００１６】まず、大口径掘削機によって、鋼管１より
も大きな径の縦穴１１を地面に掘る。この縦穴１１に鋼
管１を挿入し、縦穴１１と鋼管１の隙間に砂１２を落と
し入れ、この隙間を砂１２によって埋める。First, a large-diameter excavator is used to dig a vertical hole 11 having a diameter larger than that of the steel pipe 1 in the ground. The steel pipe 1 is inserted into the vertical hole 11, sand 12 is dropped into the gap between the vertical hole 11 and the steel pipe 1, and the gap is filled with the sand 12.
【００１７】この砂１２は、緩衝材の役目を果してい
る。震災のときには、この砂１２によって、鋼管１に加
わる衝撃が緩和される。The sand 12 serves as a cushioning material. In the event of an earthquake, the sand 12 alleviates the impact on the steel pipe 1.
【００１８】鋼管１の開口部５の周囲に、割栗石１３を
敷設し、この上に鉄筋コンクリート造りの基礎１４を設

貫通させている。また、この基礎１４の上には、蓋用枠
１７が固定され、この蓋用枠１７に外蓋１８が嵌め込ま
れる。A split stone 13 is laid around the opening 5 of the steel pipe 1, and a reinforced concrete foundation 14 is provided on the split stone 13. A water supply pipe 15 and a drain pipe 16 are passed through the foundation 14. A lid frame 17 is fixed on the base 14, and an outer lid 18 is fitted into the lid frame 17.
【００１９】給水管１５から鋼管１へと水が供給される
が、鋼管１内の水位を検出し、この水位に応じて、給水
を自動的に行うのが好ましい。また、雨水等によって、
鋼管１から水が溢れると、この溢れた水が排水管１６を
通じて下水へと導かれる。Water is supplied from the water supply pipe 15 to the steel pipe 1, but it is preferable to detect the water level in the steel pipe 1 and automatically supply water in accordance with this water level. Also, due to rainwater,
When water overflows from the steel pipe 1, this overflowed water is guided to the sewage through the drain pipe 16.
【００２０】この防火水槽を利用するときには、外蓋１
８を外し、合成樹脂製の袋９の弛んでいる上側部分を内
蓋７を介して引き上げて、この合成樹脂製の袋９の底を
抜き、この後に内蓋７を通じてホースを底まで降ろし、
鋼管１内の水を汲み出す。この合成樹脂製の袋９の底を
抜くのは、ホースの吸い口に合成樹脂製の袋９が吸引さ
れて、このホースが詰まることを防止するためである。When using this fire protection water tank, the outer lid 1
8 is removed, the loose upper part of the synthetic resin bag 9 is pulled up through the inner lid 7, the bottom of the synthetic resin bag 9 is pulled out, and then the hose is lowered to the bottom through the inner lid 7.
Pump out the water in the steel pipe 1. The bottom of the bag 9 made of synthetic resin is pulled out to prevent the bag 9 made of synthetic resin from being sucked into the mouth of the hose and clogging the hose.
【００２１】なお、鋼管１の内側の容量は、その内径を
５５ｃｍ、その高さを２３ｍとすると、略５．４ｍ3 と
なる。The inner volume of the steel pipe 1 is about 5.4 m 3 when its inner diameter is 55 cm and its height is 23 m.

る。さらに、鋼管１にひび割れが発生しても、鋼管１の
内側に発泡合成樹脂製のシート８を接着しているので、
僅かのひび割れによって、鋼管１内の水が漏れ出すこと
はない。The fire protection water tank of this embodiment is mainly composed of the steel pipe 1. Since this steel pipe 1 has sufficient elasticity, it does not easily crack even in the event of an earthquake. This steel pipe 1 has sufficient strength especially against vertical vibration. With respect to the rolling, the impact of the sand 12 is alleviated by the cushioning action of the sand 12, and therefore the rolling has a sufficient strength against the rolling. Further, even if the steel pipe 1 is cracked, since the foam synthetic resin sheet 8 is adhered to the inside of the steel pipe 1,
Water in the steel pipe 1 does not leak due to slight cracks.
【００２３】また、この防火水槽は、ビルの基礎を造る
鋼管杭を利用し、その建造もビルの基礎造りを倣って行
われるので、建設材料や工事の費用を低く抑えることが
できる。Further, this fire protection water tank uses steel pipe piles for building the foundation of the building, and the construction is performed in the same manner as the foundation building of the building, so that the cost of construction materials and construction can be kept low.
【００２４】さらに、この防火水槽の占有面積は、鋼管
１の断面積よりも僅かに広い程度である。したがって、
敷地面積が狭く、例えば住宅の敷地内であっても、邪魔
にならずに済み、この防火水槽の設置が可能である。Further, the area occupied by this fire protection water tank is slightly larger than the sectional area of the steel pipe 1. Therefore,
Even if the site area is small, for example, even on the site of a house, it does not get in the way, and this fire protection tank can be installed.
【００２５】また、この防火水槽を住宅の敷地内に設け

わなくても良い。When this fire protection water tank is provided on the premises of a house, this fire protection water tank can also be used as a water storage tank for daily life. The role of this water storage tank is also mainly for emergency use, but if there is no fire in the event of an earthquake, the water in this waterproof tank can be diverted to domestic water. Since a bag made of synthetic resin is inserted inside the fire protection water tank, in order to keep the water in the fire protection water tank sanitary, all you have to do is to periodically replace the bag made of synthetic resin, It is not necessary to wash the fireproof water tank.
