UNDERGROUND STRUCTURE, BUILDING AND METHOD FOR CONSTRUCTING UNDERGROUND STRUCTURE
To provide a method for constructing an underground structure which can be constructed at low cost even when a large vertical load acts on a part thereof.SOLUTION: A method for constructing an underground structure includes the steps of: driving a sub-structural column 21 into the ground in a central area 20A to construct a pile 12, and constructing an outside earth-retaining wall 30 and an inside earth-retaining wall 31 in an outer peripheral area 20B; constructing a first floor skeleton body 15A supported by the sub-structural column 21 in the central area 20A, and drilling the ground while suspending a timbering 32 in the outer peripheral area 20B; constructing a part of a mat foundation 13 and installing a steel column 22 in the outer peripheral area 20B, and constructing the first floor skeleton body 15B supported by the steel column 22; and drilling the ground and constructing the residual skeleton body in the central area 20A, and constructing the residual skeleton body while disassembling the inside earth-retaining wall 31 and the timbering 32 in the outer peripheral area 20B.SELECTED DRAWING: Figure 7
【課題】一部に大きな鉛直荷重が作用する場合であっても、低コストで構築できる、地下構造体の構築方法を提供する。【解決手段】地下構造体の構築方法は、中央エリア２０Ａにて地盤中に構真柱２１を打ち込んで杭１２を構築し、外周エリア２０Ｂにて外側山留め壁３０および内側山留め壁３１を構築するステップと、中央エリア２０Ａにて構真柱２１に支持させて１階床躯体１５Ａを構築し、外周エリア２０Ｂにて支保工３２を架設しながら地盤を掘削するステップと、外周エリア２０Ｂにて、べた基礎１３の一部を構築して鉄骨柱２２の建方を行い、この鉄骨柱２２に支持させて１階床躯体１５Ｂを構築するステップと、中央エリア２０Ａにて、地盤を掘削して残りの躯体を構築するとともに、外周エリア２０Ｂにて、内側山留め壁３１および支保工３２を解体しながら残りの躯体を構築するステップと、を備える。【選択図】図７
