As shown in FIG. 5, the front edge of the water flow suppressing portion 1 may be a straight slope 7 in plan view. That is, as shown in FIG. 5, the water flow restraint portion having the planar linear slope 7 is positioned so that the wide portion 14 and the narrow portion 15 face the inner surface of the bottom of the U-shaped concrete block 10. By connecting the concrete blocks 10 in an opposite relationship alternately to each other, the bent flow is formed, and the substantial water flow becomes a curved flow to form a meandering flow.
[0014]
As shown in the drawings, the water flow suppressing portion 1 is vertically low on the front end edge 11 side as described above, and the rear end portion 12 side attached to the side wall of the concrete block 10 is gradually raised. In particular, a steeply inclined surface 6 is formed at the front edge 11 portion. That is, such a water flow suppressing portion 1 is installed on one side as shown in FIG. 15 or is provided on both sides as shown in FIG. 3 so that a narrow water flow region is formed between the front end portions by the steeply inclined surfaces 6 and 6. However, a gradually widened water basin is formed between the upper surfaces of the restraining portions 1 and 1 continuously.
[0015]
A cobblestone natural stone material is embedded on the upper surface of the restraining portions 1 and 1 as described above, or a natural stone-like three-dimensional pattern 8 such as a cobblestone is formed, and in the water basin gradually made wider as described above. A refreshing stream can be formed by the flowing water stream.
