STEEL SHEET PILE, AND REMOVAL METHOD OF UPPER STEEL SHEET PILE
To provide a steel sheet pile and a removal method of an upper steel sheet pile allowing release connection between a lower steel sheet pile and the upper steel sheet pile to be easily and stably carried out.SOLUTION: A steel sheet pile 3 driven in the ground so as to separate it to an excavation side and a soil side is provided with: an upper steel sheet pile 4 of an upper part of the steel sheet pile 3; a lower steel sheet pile 5 of the steel sheet pile 3; a first anti-displacement member 21 abutting an inner surface 4a (surface of the excavation side) of the upper steel sheet plate 4 and an inner surface 5a of the lower steel sheet pile 5 (surface of the excavation side) so as to be disposed over the inner surface 4a of the upper steel sheet plate 4 and the inner surface 5a of the lower steel sheet pile 5; and a second anti-displacement member 22 abutting an outer surface 4b (surface of the soil side) of the upper steel sheet plate 4 and an outer surface 5b of the lower steel sheet pile 5 (surface of the soil side) in a state it crosses over the outer surface 4b of the upper steel sheet plate 4 and the outer surface 5b of the lower steel sheet pile 5. The first anti-displacement member 21 is fixed on both of the inner surface 4a of the upper steel sheet plate 4 and the inner surface 5a of the lower steel sheet pile 5. The second anti-displacement member 22 is fixed on both of the outer surface 4b of the upper steel sheet plate 4 and the outer surface 5b of the lower steel sheet pile 5.SELECTED DRAWING: Figure 6
【課題】下側鋼矢板と上側鋼矢板との連結を簡易かつ安定的に解除する。【解決手段】地盤に掘削側と地山側とを仕切るように打ち込まれる鋼矢板３は、鋼矢板３の上部をなす上側鋼矢板４と、鋼矢板３の下部をなす下側鋼矢板５と、上側鋼矢板４の内面４ａ（掘削側表面）と下側鋼矢板５の内面５ａ（掘削側表面）とに跨る形で上側鋼矢板４の内面４ａと下側鋼矢板５の内面５ａとに当接する第１のずれ止め部材２１と、上側鋼矢板４の外面４ｂ（地山側表面）と下側鋼矢板５の外面５ｂ（地山側表面）とに跨る形で上側鋼矢板４の外面４ｂと下側鋼矢板５の外面５ｂとに当接する第２のずれ止め部材２２とを備える。第１のずれ止め部材２１は、上側鋼矢板４の内面４ａと下側鋼矢板５の内面５ａとの双方に固定される。第２のずれ止め部材２２は、上側鋼矢板４の外面４ｂと下側鋼矢板５の外面５ｂとの一方に固定され、他方に固定されていない。【選択図】図６
