METHOD TO CONVERT EXISTING BUILDING INTO UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a method to convert an existing building into an underground structure, for effectively utilizing the existing building.SOLUTION: An earth retaining wall 2 is provided on a ground G around an existing building 1, and the ground G inside the earth retaining wall 2 is excavated. A ceiling slab 3 of a caisson work chamber is constructed at a bottom edge part of the existing building 1 inside the earth retaining wall 2, to have the ceiling slab 3 supported by an existing bearing pile that supports the existing building 1. A cutting edge 6 is provided on the ceiling slab 3 at the same time forming the caisson work chamber, and an excavation facility 8 is outfitted in the caisson work chamber. A support post 9 for an outer wall is provided such that to connect the outer wall side of the existing building 1 with the ceiling slab 3. The ground G is excavated by the excavation facility 8 while supplying compressed air into the caisson work chamber, and the existing building 1 is submerged into the ground sequentially along with the caisson 7 comprising the ceiling slab 3 and the cutting edge 6, to have the existing building 1 installed underground.SELECTED DRAWING: Figure 5
【課題】既存建物を地下化して有効利用するための既存建物の地下化工法を提供する。【解決手段】既存建物１の周囲の地盤Ｇに土留め壁２を設け、土留め壁２内の地盤Ｇを掘削する。土留め壁２内の既存建物１の下端部にケーソン作業室の天井版３を構築し、既存建物１を支持する既存の支持杭に天井版３を支持させる。天井版３に刃口６を設けるとともにケーソン作業室を形成し、ケーソン作業室に掘削設備８を艤装する。既存建物１の外壁側と天井版３を接続するように外壁用支柱９を設ける。ケーソン作業室に圧縮空気を供給しながら掘削設備８で地盤Ｇを掘削し、天井版３及び刃口６からなるケーソン７とともに既存建物１を順次地中に沈下させ、既存建物１を地中に沈設する。【選択図】図５
