摘要： PURPOSE:To provide a sufficient strength against internal pressure, to make the height of a roof low to such an extent that a coercive feeling is not given to the circumstance, and to reduce the amount of heat entering a tank by disposing girder members comprising reinforced concrete material or prestressed concrete material in a radial manner and forming a roof into a truncated cone- shape between the girder members. CONSTITUTION:A body 11 of an underground tank is formed from a bottom plate 11a of cast-in-place concrete or the like and a cylindrical side wall 11b of reinforced concrete or the like. Next, a roof 12 is formed by disposing girders 13 comprising reinforced concrete material such as reinforced concrete or prestressed concrete in a radial manner. And a roof material 14 of reinforced concrete or the like is placed between the girders 13 to form them into a truncated cone-shape. As a result, the amount of heat entering the underground tank can be reduced and the amount of boil-off gas can be decreased.

摘要： PURPOSE:To reduce the cost of construction when a roof for a tank is built while shortening the whole term of work required to construct the tank. CONSTITUTION:Forms 5 for molding a roof are borne to a sidewall 2 and arranged on the outer circumferential section of the opening 2a of the sidewall 2 in a body 4 in a ring shape, and concrete is placed into the forms 5 and cured, thus constructing a roof outer circumferential section 6. The forms 5 are mold-released and moved to the inside while being supported by an existing roof outer circumferential section 6, concrete is placed into the forms 5 and cured, and the forms 5 are shifted to the inside and the forms 5 are borne by existing concrete. A process, in which concrete is placed into the forms 5 and cured, is repeated, and concrete is projected gradually from the outer circumferential section of the opening 2a of the sidewall 2 to the inside. The roof can be constructed without installing a timbering in the body 4.

摘要： PROBLEM TO BE SOLVED: To secure a cover with a spacer formed from a steel material such as CT shape steel and further to iteratively use the spacer without finally leaving the spacer in concrete by drawing away the spacer in parallel with installation of concrete.SOLUTION: A removable spacer is formed from a vertical material which includes a tip sharpened part and is removable by being drawn upwards, and an upper end portion of the removable spacer can be fixed by fastening a fixing jig installed in an upper end of a form. The removable spacer is inserted between the form and a reinforcing-bar while bringing one side thereof into contact with the form and when the removable spacer reaches predetermined depth, the upper end portion is fixed to the form by the fixing jig. After one layer of concrete is installed, the fixing jig is unfastened and the removable spacer is pulled up from concrete by a length of one layer. By repeating such operation, the spacer is removed completely.
摘要翻译：要解决的问题：为了用诸如CT型钢的钢材形成的间隔件来固定盖子，并且通过与混凝土的安装平行地拉出隔离件，并且通过抽出间隔件而不用最终将间隔件留在混凝土中，并且迭代地使用间隔件。可拆卸间隔件由垂直材料形成，其包括尖端锐化部分并且可通过向上拉动而被移除，并且可移除间隔件的上端部分可以通过紧固安装在形式上端的固定夹具来固定。可拆卸的间隔件插入形式和加强杆之间，同时使其一侧与形式接触，并且当可移除的间隔件达到预定深度时，上端部通过固定夹具固定成形式。在安装一层混凝土之后，固定夹具松开，可拆卸的隔板从混凝土中拉出一层长度。通过重复这种操作，间隔物被完全去除。

摘要： PROBLEM TO BE SOLVED: To provide a lifting pipe and a method of constructing the lifting pipe which allow an inner pipe and a heat insulator to be installed securely and easily even if an outer pipe bends, and is low in construction cost. SOLUTION: The outer pipe 17 is constructed in a slot 27 drilled in a soil 3 at a place where a continuous underground wall 5 is scheduled to be built. Concrete 29 etc., is placed in the slot 27 to bury the outer pipe 17 in the continuous underground wall 5. Subsequently, while the outer pipe 17 and a drain pipe 9 disposed below the outer pipe 17 are used as a temporary drainage facility, a bottom plate 13, a side wall 15, etc. are constructed inside the continuous underground wall 5. While a space 35 is secured between the outer pipe 17 and an inner pipe 19 with a plurality of spacers 33 fixed on the inner pipe 19, the inner pipe 19 is inserted in the outer pipe 17, and a lower lid 25 is fixed to close the lower end of the space 35. After that, the space 35 between the outer pipe 17 and the inner pipe 19 is filled with a powdered or fluidic insulator 21, and an upper lid 23 is fixed to close the upper end of the space 35.

摘要： PROBLEM TO BE SOLVED: To provide a method of constructing a side wall which is allowed to construct in a short period, in which construction joint produced when concrete is placed is not formed, and which has excellent watertightness since cracking resulting from the construction joint does not occur when the side wall of a large-scale reinforced concrete underground structure is constructed and also provide the side wall constructed by the method.
SOLUTION: An outer reinforcement net 15b is joined to the upper part of an outer reinforcement net 15a suspended from an outer reinforcement support frame 9, and lowered by a crane 13 to suspend the outer reinforcement net 15b from the outer reinforcement support frame 9. The steps above are repeated for constructing an outer reinforcement net 15 over the entire length of an underground continuous wall 1. In the same manner, the inner reinforcement net 27 is constructed. After a form 31 is constructed, a concrete 33 is deposited at once for constructing the side wall.

摘要： PROBLEM TO BE SOLVED: To provide a structure requiring no lateral beam by constructing a panel with an excavator provided with a drum rotatable around a shaft and an excavation section having different excavation depths near the end sections of the drum and near the center, providing a recess on one of preceding panels and a succeeding panel and a projection on the other, and engaging the recess and the projection. SOLUTION: Portions of preceding panels 11a, 11b are excavated by an excavator, concrete is placed, and a reinforced cage is arranged. The portion of a succeeding panel 13 is excavated while the end sections of the preceding panels 11a, 11b are excavated into a trapezoidal shape, concrete is placed, and a reinforced cage is arranged. The end sections of the preceding panels 11a, 11b are excavated by the excavator to form a recess when the succeeding panel 13 is excavated. When concrete is placed to the portion of the succeeding panel 13, a projection can be formed on the succeeding panel 13, and a joint structure capable of transferring shearing force is formed. A structure requiring no lateral beam is obtained.
