EXTENSION METHOD FOR UNDERGROUND FACILITY
PROBLEM TO BE SOLVED: To provide an extension method for an underground facility that may be executed relatively simply at a low cost.SOLUTION: An extension method for an underground facility is for installing an additional seismic isolator 7 in an existing building having an existing pile 1 and an existing foundation body 2, and includes: an excavation step in which excavation is performed underneath the existing foundation body 2 for exposing a part of the existing pile 1; a cutting step in which an outer periphery of the exposed portion of the existing pile 1 is cut; a new foundation body installation step in which a new foundation body 4 is formed underneath the existing foundation body 2; a first replacement step in which the existing foundation body 2 is supported by a temporary support member 6 erected on the new foundation body 4; an existing pile removal step in which the exposed portion of the existing pile 1 is removed; an extension step for the underground facility in which the additional seismic isolator 7 is installed between the new foundation body 4 and the existing foundation body 2; a second replacement step in which the existing foundation body 2 is supported by the seismic isolator 7; and a temporary support member removal step in which the temporary support member 6 is removed.SELECTED DRAWING: Figure 7
【課題】比較的簡易かつ安価に施工をすることが可能な地下施設増設方法を提案する。【解決手段】既設杭１と既設基礎体２とを備える既存建物に免震装置７を増設する地下施設増設方法であって、既設基礎体２の下方を掘削して既設杭１の一部を露出させる掘削工程と、既設杭１の露出部分の外周を切削する切削工程と、既設基礎体２の下方に新設基礎体４を形成する基礎体新設工程と、新設基礎体４に立設させた仮支持材６により既設基礎体２を支持する第一の受替工程と、既設杭１の露出部分を撤去する既設杭撤去工程と、新設基礎体４と既設基礎体２との間に免震装置７を増設する地下施設増設工程と、既設基礎体２を、免震装置７で支持する第二の受替工程と、仮支持材６を撤去する仮支持材撤去工程とを備えている。【選択図】図７
