PROBLEM TO BE SOLVED: To rationally construct an embankment for a high Tsunami in a short period in the weak ground of a seabed.;SOLUTION: A tide embankment for a Tsunami is provided so that a steel pipe 1 is driven in 2-3 rows at an equal interval in parallel in a shape of an embankment as if an express highway is constructed, and is respectively extended when a predetermined height is not produced by one steel pipe 1, and next, the steel pipe 1 is laterally and longitudinally connected by a steel frame 6, and next, sediment 4 is inputted to the inside and the outer periphery of a frame, and is landfilled up to the almost sea surface vicinity, and next, a steel sheet pile 7 is closely driven along a row of a front face and a back face of the steel pipe 1 for forming the embankment, and its upper part connects the steel pipe and a sheet pile by horizontally extending a steel sheet pile connection material 7, and a sea surface upper part of the top end of the embankment installs a wall 3 by a panel and concrete along a row of the front face and the back face, and next, the sediment 4 is inputted and filled up to the top end between its walls, and the sediment is piled up in a natural slope shape up to the sea bottom from the top end on the front face of the embankment, and the back face is piled up with the sediment in a natural slope shape under a sea surface, and a pipe and a thinning material 5 are also driven in large numbers in a seabed.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
