CONSTRUCTION METHOD FOR COFFERDAM STRUCTURE AND COFFERDAM STRUCTURE
To provide a construction method for a cofferdam structure capable of securing cut-off performance and reducing the labor and time of the construction.SOLUTION: A construction method for a cofferdam structure comprises steps of: installing multiple hollow piles 10 with upper ends opened in a water bottom 2 around a work area; installing sheet support members 20 fixed with a first waterproof sheet 40 on the water bottom 2 at a side separated from the work area from the hollow piles 10; inserting column bodies 30 into each of the hollow piles 10; installing a second waterproof sheet 50 by spreading between the column bodies 30; and detachably connecting the second waterproof sheet 50 to the first waterproof sheet 40.SELECTED DRAWING: Figure 1
【課題】止水性能を確保できるとともに、施工の手間と時間を軽減できる仮締切構造体の施工方法を提供する。【解決手段】作業エリアの周囲の水底２に上端が開口した中空杭１０を複数打設する杭打設工程と、中空杭１０よりも作業エリアから離間した側の水底２に、第一防水シート４０が固定されたシート支持部材２０を設置するシート支持部材設置工程と、各中空杭１０に柱体３０を挿入する柱体挿入工程と、柱体３０同士の間に第二防水シート５０を着脱可能に掛け渡す第二防水シート設置工程と、第二防水シート５０を第一防水シート４０に着脱可能に連結する防水シート連結工程と、を備える。【選択図】図１
