INSTALLATION METHOD OF STEEL PLATE CELL, AND STEEL PLATE CELL

To suppress outflow of a filler without being affected by buoyance and water pressure when sinking a steel plate cell underwater.SOLUTION: An installation method of a steel plate cell 10 is related to the steel plate cell 10 which includes a cylindrical cell body 11 and which is installed in a paving stone portion 4 formed in an excavated bed portion 3 of a water bottom ground 2. The installation method comprises: a body installation step of installing the cell body 11 on an upper face of the paving stone portion 4 in a state where its axial direction becomes a vertical direction; a blocking step of, after the body installation step, blocking an opening in a bottom portion of the cell body 11 with a bottom cover 13; an infilling step of, after the blocking step, filling a filler 14 into an inside of the cell body 11; and a backfilling step of backfilling the excavated bed portion 3.SELECTED DRAWING: Figure 1 【課題】鋼板セルを水中に沈める際に浮力や水圧の影響を受けることなく、中詰材の流出を抑制すること。【解決手段】鋼板セル１０の設置方法は、円筒状のセル本体１１を有し、水底地盤２の床堀部３に形成された敷石部４に設置される鋼板セル１０に係るものであり、セル本体１１を軸方向が鉛直方向となる状態で敷石部４の上面に設置する本体設置工程と、本体設置工程の後、セル本体１１の底部の開口を底蓋１３によって閉塞する閉塞工程と、閉塞工程の後、セル本体１１の内部に中詰材１４を充填する中詰め工程と、床堀部３を埋め戻す埋め戻し工程とを備えている。【選択図】図１
