STEEL SHEET PILE CONTINUOUS WALL CONSTRUCTION METHOD
To provide a construction method that does not interrupt the digging range by an auger when constructing a steel sheet pile continuous wall in which steel sheet piles including joints on both sides of a main body are connected in the horizontal direction to the ground using the auger together.SOLUTION: A steel sheet pile n04 is applied in which an extension length L5 from a main body a02 of a rear joint a03 has at least a length obtained by combining a joint margin L3 of a front joint a04 and the rear joint a03 with an extension length L2 from the main body a02 of the front joint a04. Preferably, an extra length L4 is taken. A drilling rotational diameter range n15 of a radius R by an auger head m13 is configured to include a front end n12 of the front joint a04. That is, (radius R)≥(length L1)+(length L2). The same drilling rotational diameter range is configured so as not to include a position n16 ahead of a rear end n13 of the steel sheet pile n04 by a length corresponding to the joint margin L3. That is, (radius R)<(length L1)+(length L2)+(length L4).SELECTED DRAWING: Figure 4
【課題】継手を本体の両側に備える鋼矢板を横方向に連結した鋼矢板連続壁を、オーガを併用して地盤に構築するにあたり、オーガによる掘削範囲を途切れさせない工法を提供する。【解決手段】後方継手ａ０３の本体ａ０２からの延出長さＬ５は、前方継手ａ０４の本体ａ０２からの延出長さＬ２に、前方継手ａ０４との後方継手ａ０３との継手しろＬ３を合せた長さを少なくとも有する鋼矢板ｎ０４を適用する。好ましくは余裕分の長さＬ４をとる。オーガヘッドｍ１３による半径Ｒの掘削時回転径範囲ｎ１５が前方継手ａ０４の前端ｎ１２までを含むようにする。すなわち、（半径Ｒ）≧（長さＬ１）＋（長さＬ２）である。同掘削時回転径範囲が、鋼矢板ｎ０４の後端ｎ１３から継手しろＬ３に相当する長さだけ前方の位置ｎ１６までを含まないようにする。すなわち、（半径Ｒ）＜（長さＬ１）＋（長さＬ２）＋（長さＬ４）である。【選択図】図４
