Document Type and Number:
Japanese Patent JP7296311
Kind Code:
B2
Abstract:
To provide a construction method of an underground structure allowing a short construction period to be achieved when constructing a part of the underground structure with an inverted construction method and the other part of the underground structure with a normal construction method.SOLUTION: A construction method of an underground structure comprises: a step S2 of constructing a first-story floor skeleton in an inverted construction area Q as a preceding floor 40; and a step S3 of installing side by side a plurality of struts 30 extending in a predetermined direction between the preceding floor 40 and a circumferencial mountain retention wall 50. In the step S2, only a part of the first-story floor skeleton positioned on an extension line Y of the struts 30 is constructed as the preceding floor 40 in a plan view.SELECTED DRAWING: Figure 5
