On the other hand, a large amount of cement is required for the construction of a dam, and in addition to enormous construction costs, a large amount of mortar, concrete, etc. are produced and transported, so that the operating amount of a batcher plant, a crane, etc. becomes large, which causes a failure or failure. It led to an accident. These are more of a concern because there is a tendency to build many diversifying dams such as snow dams, sediment removal dams, volcanic dams, and garbage disposal dams.

As shown in FIGS. 1 to 3, as a dam structure, a base concrete 3 is laid at a predetermined height over a riverbed 1 and both left and right banks 2 serving as a dam site. On the both sides of the side, the reinforcing bar retaining wall concretes 4 and 5 on the upstream and downstream surfaces are juxtaposed at a predetermined interval. In this way, the concave portion 6 is formed by the base concrete 3 and the retaining wall concrete 4, 5 on the upstream and downstream sides provided on the upper portion thereof, and whether the concave portion 6 is merely industrial waste or originally a harmful substance. The harmful substances 7 from which harmless substances have been removed are separately added. The mortar 8 is introduced from both sides of the concrete of the retaining wall of the industrial waste 7 in the recess 6 and, if necessary, from above, and the specific gravity of the mortar is the industrial waste 7.
When it is larger, it enters the gaps of the industrial waste and mixes, and these are integrally hardened as a mixed solidified product to be filled in the dam. At the upper part of the filling material, this is hermetically sealed, and the ceiling concrete 9 is cast and formed over the retaining wall concretes 4 and 5 on the upstream and downstream surfaces. On the vertical and horizontal connecting surfaces of the concrete dam, grouting is performed on the horizontal and vertical joints of the body so that the harmful substances do not flow out.

Next, main pipes 12 for mortar casting and branch pipes (not shown) from the main pipes are installed vertically and horizontally at predetermined intervals inside each retaining wall concrete at the upstream and downstream sides. After throwing in about 3 m of waste 7, mortar is placed. The placed mortar is hardened by filling the space between the industrial wastes 7 with no gap by its own weight. The alternating inputs of the industrial waste 7 and the mortar 8 are repeatedly carried out by stacking them every 3 m after solidification.
