る。In conventional concrete underground tanks for storing low-temperature liquids (LNG, LPG, etc.), as shown in Figure 1, the outer shell wall a of the tank is constructed by construction work in the part below the ground surface (G, L,). The ease of construction and design advantages include the fact that the outer shell wall built underground can be used as a water-stop wall during construction, and that external pressures such as earth pressure and water pressure C can be applied to the concrete cross section.
Because a reinforced concrete structure (RC structure) was adopted with emphasis on the compressive force exerted by

This was done with the aim of obtaining an economical semi-underground tank that takes advantage of the ease of construction work of structure C) and exhibits the structural advantages. In a semi-underground tank equipped with an inner tank that covers the upper surface and the inner surface of the outer shell wall, the area below the ground surface is made of reinforced concrete,
This relates to the outer shell wall of a semi-underground tank, which is characterized by having a prestressed concrete structure above the ground surface.
以下本発明の半地下タンクの外殻壁の実施例につき、添
付の図面に基づいて説明する。Embodiments of the outer shell wall of a semi-underground tank according to the present invention will be described below based on the attached drawings.

さまでＲＣ構造としコンクリ−ドナ打設する。In Figure 2, 1 is the foundation bottom, 2 is the underground part of the outer shell wall, and 3
is the above-ground part of the outer shell wall, 4 is the inner tank, 5 is the roof, the foundation bottom 1 is an RC structure, and the outer shell wall 2 is an RC structure up to a height that reaches the alley surface CG, L,), and concrete is poured. .
更に、前記外殻壁２の延長上にこれと内径が等しいＰＣ
構造の外殻壁３を外殻壁地中部２に接続して構築する。Further, on the extension of the outer shell wall 2, there is a PC having the same inner diameter as the outer shell wall 2.
The outer shell wall 3 of the structure is connected to the outer shell wall underground part 2 and constructed.
外殻壁地中部２の上部端面には地上部３と地中部２とを

殻壁３に垂直方向及び水平方向のプレストレスを与える
。A necessary number of reinforcing bars are inserted into the upper end face of the underground part 2 of the outer shell wall to firmly connect the above-ground part 3 and the underground part 2, and give vertical and horizontal prestress to the above-ground part outer shell wall 3. .
尚、外殻壁地上部３の外側には盛土７を施工し、内側に
は円筒形のタンク貯蔵部の全面を覆う内槽４が設置され
る。An embankment 7 is constructed on the outside of the above-ground part 3 of the outer shell wall, and an inner tank 4 is installed inside to cover the entire surface of the cylindrical tank storage section.
外殻壁地中部２はＲＣ構造であるので、建設工事が容易
であり、又外殻壁２の外側の土圧または水圧等の外圧ｇ
はタンク液８の内圧りに対抗して外殻壁２に圧縮作用を
及ぼし液密性を向上させる。Since the outer shell wall underground part 2 has an RC structure, construction work is easy, and external pressure such as earth pressure or water pressure on the outside of the outer shell wall 2 is reduced.
exerts a compressive action on the outer shell wall 2 against the internal pressure of the tank liquid 8, thereby improving liquid tightness.
又、外殻壁地上部３はＰＣ構造であるので壁の厚みを大
きくしなくても内圧りに充分対抗でき経済的である。Moreover, since the above-ground part 3 of the outer shell wall is of a PC structure, it is economical because it can sufficiently resist internal pressure without increasing the thickness of the wall.
又厚みが少ないので外殻壁３の内外の温度差に起因する
熱応力が小さく、更に外殻壁断面は膚に圧縮状態にある
ので液密性も優れている。Furthermore, since the thickness is small, thermal stress caused by the temperature difference between the inside and outside of the outer shell wall 3 is small, and since the cross section of the outer shell wall is compressed against the skin, it has excellent liquid tightness.
尚、本発明は前述の実施例にのみ限定されるものではな
く、本発明の要旨を逸脱しない範囲内において種々変更
をなし得ることは勿論である。It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

、等の効果を奏し得る。Since the present invention has the above-mentioned configuration, the underground part can fully enjoy the benefits of the conventional RC structure, while the above-ground part can use the PC structure to reduce the thickness of the wall, making it extremely economical. Moreover, it is possible to obtain an outer shell wall with high strength, high liquid-tightness, and low thermal stress.
