PROBLEM TO BE SOLVED: To provide a steel sheet pile concrete block that enables work for the assembly, installation and removal of a temporary cofferdam and temporary soil retaining works to be easily executed in an emergency on the occurrence of disasters such as an earth slide and a collapse of a river bank, and a construction method for the same.SOLUTION: A precast concrete block, in which a steel sheet pile and concrete are integrated together, enables repeated use and improve cut-off properties. A large number of steel sheet pile concrete blocks for a temporary cofferdam and temporary soil retaining works, both the longitudinal ends of which have joint parts, are connected together. Field work can be rapidly and easily executed only by transportation and installation to enable shortening of a construction period and cost reduction.SELECTED DRAWING: Figure 1
【課題】 土砂崩れや河川堤防決壊の災害発生緊急時において、仮締切工や仮土留工の組立設置、撤去作業を容易に実施可能とする鋼矢板コンクリートブロックとその構築方提供する。【解決手段】 鋼矢板とコンクリートを一体化させたプレキャストコンクリートブロックにより、繰り返しの使用を可能にし、止水性の向上、その長手方向の両端部に継手部を有する多数個を接続させた仮締切工、仮土留工用の鋼矢板コンクリートブロックを提供し、現場での作業を運搬設置のみで施工を迅速・容易にし、工期の短縮・コスト削減を可能にした。【選択図】図１
