Abstract

PURPOSE: To use a continuous wall as a part of a round underground type structure by a method in which a continuous wall inserted with a core material is constructed, the ground inside the continuous wall is excavated, and concrete for side wall is placed into ring beams set during the excavation.
CONSTITUTION: Dowel reinforcing bars 7 are welded to H-steels 2 in advance, and the ground is excavated along a guide ring 4 and the soil is replaced by cement mortar. The H-steels 2 are inserted into the cement mortar to form a continuous wall 1. The ground is then excavated to a given depth while setting ring beams 3 inside, and the dowel reinforcing bars 7 are exposed in order by chipping. Circumferential reinforcing bars 9 and vertical reinforcing bars 10 are then set, and concrete 8 for side wall is placed while embracing the ring beams 3 and the dowel reinforcing bars 7. The sheathing continuous wall can thus be utilized as a part of the base structure, and the thickness of the side wall concrete can be greatly reduced.
