[0045] Then, a reinforcing material 4 composed of cement mortar, concrete mixed with admixtures and other consolidation materials is poured from bottom to top through the central groove 201 to fill the gap between the miter assemblies 2;

[0046] Finally, after excavating the foundation on the back side of the water retaining assembly 3, the cast-in-place concrete 5 is constructed using the water retaining assembly 3 as some templates. The cross-section of the cast-in-place concrete 5 is triangular or trapezoidal, and its right-angled sides are in contact with the water retaining assembly 3. After the strength reaches the standard requirements, the template is removed and the earth behind the embankment is backfilled to construct the embankment top structure 6.
