【発明の詳細な説明】 〔産業上の利用分野〕 この発明はLNGやPLG或いは原油を貯蔵するための地下貯
蔵タンクに関するものである。TECHNICAL FIELD The present invention relates to an underground storage tank for storing LNG, PLG or crude oil.
最近では、LNGやLPG等の低温液化ガスや原油等の液体用
の貯蔵タンクとして、安全面等の観点から地下貯蔵タン
クが建設されるようになってきている。Recently, underground storage tanks have been constructed as storage tanks for liquids such as low-temperature liquefied gas such as LNG and LPG and liquids such as crude oil from the viewpoint of safety.
この種の地下貯蔵タンクとして、地盤を掘削する為に構
築された地中連続壁の内側にこれとは別に地下貯蔵タン
クの側壁を構築し、この側壁と地中連続壁との間を埋め
戻し、且つこの部分に水を溜めて地下貯蔵タンクの側壁
に水圧を作用させることによって側壁に作用するタンク
内のガス圧や液圧に抵抗できるようにした構成の地下貯
蔵タンクが実用化されている。As an underground storage tank of this kind, a side wall of the underground storage tank is built inside the underground continuous wall constructed for excavating the ground separately, and the space between this side wall and the underground continuous wall is backfilled. In addition, an underground storage tank having a structure capable of resisting gas pressure or liquid pressure in the tank acting on the side wall by accumulating water in this portion and applying water pressure to the side wall of the underground storage tank has been put into practical use. ..
また、地下貯蔵タンクの側壁を地盤掘削面の内側にこれ
より離して構築し、この地盤掘削面と側壁との間を埋め
戻し、且つこの部分に前記地下貯蔵タンクと同様に水を
溜めて地下貯蔵タンクの側壁に水圧を作用させるように
した構成の地下タンクも実用化されている。In addition, the side wall of the underground storage tank is constructed inside the ground excavation surface, apart from this, the space between the ground excavation surface and the side wall is backfilled, and water is accumulated in this part in the same manner as the underground storage tank to store the underground. An underground tank having a structure in which water pressure is applied to the side wall of the storage tank has also been put into practical use.
この種の地下貯蔵タンクはいずれも側壁の厚さを薄くで
きる為、工事費の低減が図れるというメリットがある。All of these types of underground storage tanks have the merit of being able to reduce construction costs because the side walls can be made thinner.
その半面、側壁の施工に際し、側壁の外側にも型枠を組
み立てる必要がある為、工事日数及び工事費が嵩むこと
を免れない。On the other hand, when constructing the side wall, it is necessary to assemble the formwork on the outer side of the side wall, which inevitably increases the construction days and construction cost.
また、側壁の外側に隙間を設ける必要がある為、地下タ
ンクの径より相当広範囲に地盤を掘削する必要があり、
掘削土量が大幅に増え、その処理が問題となる。Also, because it is necessary to provide a gap outside the side wall, it is necessary to excavate the ground in a considerably wider area than the diameter of the underground tank,
The amount of excavated soil will increase significantly, and its treatment will be a problem.
この発明はこのような前記従来の課題を解消する為に提
案されたもので、工事日数及び工事費の大幅低減を可能
にすると共に簡略施工を可能にした地下貯蔵タンクを提
供することを目的とするものである。The present invention has been proposed in order to solve the above-mentioned conventional problems, and an object thereof is to provide an underground storage tank that enables a significant reduction in the number of construction days and construction costs and simplification construction. To do.
この発明はLNGやLPG或いは原油を貯蔵するための地下貯
蔵タンクに関するもので、地盤面下に以下貯蔵タンクを
鉄筋コンクリートによって構築し、当該地下貯蔵タンク
の側壁と当該側壁の外側に構築された地中連続壁若しく
は地盤掘削面との間に透水マットを介在し、且つこの部
分に水を略満水状態に溜めた構成とすることにより前記
目的を達成するものである。The present invention relates to an underground storage tank for storing LNG, LPG, or crude oil. The above object is achieved by interposing a water permeable mat between the continuous wall or the ground excavation surface, and having a structure in which water is stored in a substantially full state.
以下、この発明を図示する一実施例に基づいて説明す
る。Hereinafter, the present invention will be described based on an illustrated embodiment.
この発明に係る地下貯蔵タンク１は、地盤面下に現場打
ち鉄筋コンクリートによって構築されている。The underground storage tank 1 according to the present invention is constructed of cast-in-place reinforced concrete below the ground surface.
当該地下貯蔵タンク１の側壁２は予め構築された地中連
続壁３の内側（第１図参照）若しくは地盤掘削面４の内
側（第２図参照）に構築されている。The side wall 2 of the underground storage tank 1 is built inside a previously constructed underground continuous wall 3 (see FIG. 1) or inside a ground excavation surface 4 (see FIG. 2).
また、当該側壁２と地中連続壁３若しくは地盤掘削面４
との間には、その全体にわたって透水マット５が介在さ
れ、且つこの部分に水が略満水状態に溜められている。In addition, the side wall 2 and the underground continuous wall 3 or the ground excavation surface 4
The water permeable mat 5 is interposed between the and, and water is stored in this part in a substantially full state.
したがって、地下貯蔵タンク１の側壁２には水圧が作用
し、地下貯蔵タンク１内のガスや液体による内圧に充分
抵抗できるようにしてある。Therefore, the water pressure acts on the side wall 2 of the underground storage tank 1 to sufficiently resist the internal pressure of the gas or liquid in the underground storage tank 1.
この為、側壁２の壁厚を可能な限り薄くすることがで
き、経済施工が可能になる。Therefore, the wall thickness of the side wall 2 can be made as thin as possible, which enables economical construction.
尚、透水性マット５にはポリプロピレン樹脂が使用さ
れ、その表面は透水性のシートによって覆われている。A polypropylene resin is used for the water-permeable mat 5, and its surface is covered with a water-permeable sheet.
また、透水性マット５は地中連続壁３若しくは地盤掘削
面４の内側に側壁２のコンクリートを打設する前に取り
付けておくことにより側壁２の外型枠として利用するも
のとする（透水性マットには側壁コンクリートのモルタ
ルは流入しない。）。Further, the water-permeable mat 5 is used as an outer form of the side wall 2 by attaching it to the inside of the underground continuous wall 3 or the ground excavation surface 4 before placing the concrete of the side wall 2 (water permeability). Side wall concrete mortar does not flow into the mat.)
さらに、地震時の土圧に対し、側壁２と地中連続壁３で
抵抗する場合には、透水性マット５を地中連続壁３の内
側にその全面にわたってメッシュ状に取り付けることに
より（第５図及び第６図参照）地震時の土圧を側壁２に
伝達する構造とするものとする。Furthermore, when the side wall 2 and the underground continuous wall 3 resist the earth pressure at the time of an earthquake, the water-permeable mat 5 is attached to the inside of the underground continuous wall 3 over the entire surface in a mesh shape (fifth aspect). (See Fig. And Fig. 6) The structure shall be such that earth pressure during an earthquake is transmitted to the side wall 2.
この発明は以上の構成からなるので以下の効果を有す
る。Since the present invention is configured as described above, it has the following effects.
掘削土量を可能な限り少なくすることができる為、
掘削土量の処分に余計な手間暇を費やす必要がない。Since the amount of excavated soil can be minimized,
There is no need to spend extra time and effort to dispose of excavated soil.
側壁の施工に際し、側壁の外型枠として地中連続壁
や地盤掘削面の内側に取付けた透水性マットを利用でき
る為、側壁の内側にのみ内型枠を設置すればよく、工事
日数及び工事費を大幅に節約することができると共に簡
略施工が可能である。When constructing a side wall, since a water-permeable mat installed inside the underground continuous wall or the ground excavation surface can be used as the outer form of the side wall, it is sufficient to install the inner formwork only inside the side wall. The cost can be greatly saved and simple construction is possible.
地下貯蔵タンクの貯蔵ガスや液体による内圧に対し
水圧によって抵抗する構成になっている為、側壁の壁厚
を可能な限り薄くすることができる。Since the internal pressure of the storage gas or liquid in the underground storage tank is resisted by water pressure, the wall thickness of the side wall can be made as thin as possible.
