RESTORATION METHOD OF EXISTING FOUNDATION, AND RESTORATION STRUCTURE OF EXISTING FOUNDATION
PROBLEM TO BE SOLVED: To inhibit sinking of an existing ground improvement structure and lift a sunken existing foundation thereon to restore.SOLUTION: An existing ground improvement structure 40 is constructed under a foundation 30 that is constructed in a ground 10. A one-story slab 12 and a column 16 are joined in and supported by the foundation 30. In addition, a beam 20 that supports a two-story slab 18 is joined on the column 16. The foundation 30 and the existing ground improvement structure 40 has been sunk due to a massive earthquake and the like more than expected. A new ground improvement structure 50 is constructed immediately under the existing ground improvement structure 40 that is in sunken condition. Also, mortar 60 is injected between the foundation 30 and the existing ground improvement structure 40, and the foundation 30 is lifted due to injection pressure and is restored at a design GL.SELECTED DRAWING: Figure 1
【課題】既存地盤改良体の沈下を抑制し、その上の沈下した既存基礎を押し上げて復元する。【解決手段】地盤１０に構築された基礎３０の下には、既存地盤改良体４０が構築されている。基礎３０には、一階のスラブ１２及び柱１６が接合され支持されている。また、柱１６には、二階のスラブ１８を支持する梁２０が接合されている。この基礎３０及び既存地盤改良体４０は、想定以上の大地震等により沈下している。沈下した状態の既存地盤改良体４０の直下には新設地盤改良体５０が構築されている。そして、基礎３０と既存地盤改良体４０との間には、モルタル６０が注入され、注入圧によって基礎３０が押し上げられ、設計ＧＬに復元されている。【選択図】図１
