摘要： PROBLEM TO BE SOLVED: To absorb an erection error of a side wall, minimize the ground occupation area and the period associated with construction work, suppress influence on the surrounding environment to a requisite minimum, facilitate transportation and field work, and to secure structural strength, in an underground structure having large overburden.
SOLUTION: An embedment part 2b in which an insertion metal is embedded to a predetermined depth from an upper end face is formed at the position where each of both side wall parts are to be erected, and precast concrete side walls 2 provided with a plurality of temporary steel materials 2B detachably arranged in an upwardly projecting manner for lateral resistance against an earth/water pressure are erected in the ground. After the ground is excavated and removed to the position where a top slab is to be constructed between the side walls 2, concrete is placed between the precast concrete side walls 2, 2 and a lower side of the embedment part 2b while keeping away from the same so that the precast concrete side walls 2 may be joined and integrated. Then, a top slab part 3 forming a body structure is constructed, and the shallow ground part above the top slab part is completed antecedently.

In the first step, precast concrete side walls 2, 2 forming a main body structure are built in the ground at locations where both side wall portions are to be erected, and a shallow ground portion between the precast concrete side walls 2, 2 is excavated and removed. Thereafter a precast concrete top slab 4 forming the main body structure is extended between the precast concrete side walls 2, 2, and then the excavated portion is back-filled, to thereby antecedently complete the shallow portion above the top slab. In the second step, excavation is carried out in a ground portion enclosed by the precast concrete side walls 2, 2 and the precast concrete top slab 4, which is deeper than the top slab, and finally excavation is carried out in a ground portion down to a depth at which a bottom slab 5 is constructed. In the third step, concrete is placed in a bottom slab construction area, and unitary combination of the bottom slab with the precast concrete side walls 2 is achieved.
