APPARATUS AND METHOD FOR IMMERSING CAISSON SKELETON
PROBLEM TO BE SOLVED: To reliably and efficiently perform the inclination correction and immersion of a caisson skeleton by properly controlling the skin friction of the caisson skeleton.SOLUTION: An apparatus for immersing a caisson skeleton includes: injection nozzles 20 which are provided in a plurality of places in such a manner that installation places are different from one another in circumferential and vertical directions of the caisson skeleton 10 and which can perform upward high-pressure injection of a liquid from a peripheral surface of the caisson skeleton 10; a friction meter 30 which is provided near each of the injection nozzles 20 to measure skin friction of the caisson skeleton 10; and liquid injection control means 50 for controlling liquid injection from each of the injection nozzles 20 on the basis of a friction value measured by each friction meter 30.SELECTED DRAWING: Figure 1
【課題】 ケーソン躯体の周面摩擦を適切に制御して、ケーソン躯体の傾き修正や沈設を確実かつ効率的に行う。【解決手段】 ケーソン躯体１０の周方向及び上下方向に設置箇所をそれぞれ異ならせて複数箇所に設けられ、当該ケーソン躯体１０の周面から上方へ向かって液体を高圧噴射可能な噴射ノズル２０と、各噴射ノズル２０の近傍に設けられ、ケーソン躯体１０の周面摩擦を測定する摩擦計３０と、各摩擦計３０で測定した摩擦値に基づいて、各噴射ノズル２０からの液体の噴射を制御する液体噴射制御手段５０とを備える。【選択図】図１
