CONSTRUCTION METHOD OF DOUBLE SHEET PILE STRUCTURE AND DOUBLE SHEET PILE STRUCTURE
PROBLEM TO BE SOLVED: To provide a double sheet pile structure construction method and a double sheet pile structure capable of efficiently and stably constructing a double sheet pile structure even under a condition of deepwater where a double sheet pile structure is impossible with ordinary steel pipe sheet piles.SOLUTION: The double sheet pile structure is constituted of at least two separated parts which are vertically aligned, i.e. front sheet piles and rear sheet piles. The construction method of the double sheet pile structure includes: drilling the foundation ground at the water bottom; installing guide frames 10; installing separated lower sheet piles 11A, 12A via the guide frames; feeding solidified soil 21 between the installed lower front sheet piles and the rear sheet piles as a filling material; installing the separated upper sheet piles on the lower sheet piles; and feeding a solidified soil between the installed upper front sheet piles and the rear sheet piles as a filling material.
【課題】通常の鋼管矢板では二重矢板構造が成立しないような大水深下においても効率的かつ安定的に二重矢板構造物を構築可能な施工方法および二重矢板構造物を提供する。【解決手段】この二重矢板構造物の施工方法は、二重矢板構造物は前方矢板および後方矢板が上下に少なくとも二つに分割された構造を有し、水底の基礎地盤を床掘してから導枠１０を設置し、導枠を通して分割された下段の矢板１１Ａ，１２Ａを打設し、打設された下段の前方矢板と後方矢板との間に中詰材として固化処理土２１を投入し、下段の矢板に対し分割された上段の矢板を打設し、打設された上段の前方矢板と後方矢板との間に中詰材として固化処理土を投入する。【選択図】図５
