RESTRICTION STRUCTURE FOR CO-SINKING, AND METHOD FOR SETTLING CAISSON
PROBLEM TO BE SOLVED: To provide a restriction structure for co-sinking and a method for settling a caisson that prevent co-sinking of peripheral grounds and neighboring structures efficiently.SOLUTION: A restriction structure for co-sinking of this invention comprises: a caisson 10 that is installed in a ground G, and comprises a foundation bottom part 15 having an edge 13 and a slab 14 and a sidewall part 12 made by lamination of annular bodies 11 having a smaller outer shape than that of the foundation bottom part in a plan view, on the foundation bottom part; a friction reduction part 21 configured in a space formed between the sidewall part and the ground; and stabilizing liquid 20 stored in the friction reduction part.SELECTED DRAWING: Figure 1
【課題】周辺地盤や近接構造物の共下がりをより効果的に抑制することが可能な共下がり抑制構造及びケーソンの沈下方法を提供する。【解決手段】地盤Ｇに設置され、刃口１３及びスラブ１４を有する基礎底部１５と、平面視において基礎底部の外形より小さい外形を有する環状体１１が基礎底部上に積層された側壁部１２と、を備えたケーソン１０と、側壁部と地盤との間に形成される空間で構成される摩擦低減部２１と、摩擦低減部に貯留された安定液２０と、を備えている。【選択図】図１
