CONSTRUCTION METHOD OF UNDERGROUND STRUCTURE BY INVERTED CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To enable construction of a building frame of an underground structure by an inverted construction method, without using a suspended mold.SOLUTION: A construction method of an underground structure by an inverted construction method includes the following steps for: (a) excavating the ground between earth retaining walls to a level below a scheduled place of construction of a building frame; (b) installing a timbering frame below the scheduled place of construction, the timbering frame supporting a mold used for constructing the building frame at the scheduled place of construction, and a timbering for the mold; and (c)(c1) constructing the building frame at the scheduled place of construction, at the same time (c2) excavating the ground below the timbering frame.SELECTED DRAWING: Figure 4
【課題】逆打工法における地下構造物の構築時において、吊り下げ式の型枠を用いずに躯体構築を可能とすること。【解決手段】逆打工法における地下構造物の構築方法であって、（ａ）土留壁間の地盤を、躯体の構築予定箇所の下方まで掘削し、（ｂ）前記構築予定箇所の下方に、該構築予定箇所の躯体構築に用いる型枠と、該型枠の支保工と、を支持する、支保工架台を設置し、（ｃ）（ｃ１）前記構築予定箇所での躯体の構築作業と、（ｃ２）前記支保工架台の下方の地盤の掘削作業と、を並行して行うことを特徴とする。【選択図】図４
