DEMOLITION METHOD OF UNDERGROUND STRUCTURE
To provide a demolition method of an underground structure in which a boring work by an auger machine is possible even though filled earth and a banking are filled on demolished concrete crushed pieces, in a situation that boring is carried out to install an H-shaped steel and a pile at reconstruction in a case where an underground skeleton is demolished and a ground is constructed.SOLUTION: In a demolition method of an underground structure in which an underground skeleton 1 is gradually demolished from a bottom layer at a height at which an adjacent area does not collapse, in which filled earth 5 is filled into a gradually formed demolition space to form a temporary base 6 supporting a remaining skeleton and in which a vacant lot is constructed by banking in a bottom region and laminating raised ground to a top layer, a boring region 3 to be bored at reconstruction is formed by laminating filled earth from which crushed pieces generated in demolition are removed, from the bottom layer to the top layer.SELECTED DRAWING: Figure 7
【課題】地下躯体の解体を行って地盤を構築する場合、建替えの際、H鋼や杭を立設するため穿孔を行うこととなるが、解体したコンクリート破砕片上に埋め込み土類や盛土が充填されていても、オーガマシンによる穿孔作業が可能となる地下構造の解体方法を提供する。【解決手段】地下躯体１を最下層から隣接地が崩壊しない高さで段階的に解体を行い、段階的に形成される解体空隙に埋め込み土類５を充填して残存躯体を支える仮土台６を形成するとともに底部領域に盛土して嵩上げ地盤を最上層まで積層して更地を構築する地下構造の解体工法において、建替え時に穿孔される穿孔領域３は最下層から最上層まで解体時に発生する破砕片を除いた埋め込み土類をもって積層形成するものである。【選択図】図７
