  The present invention relates to an earth and sand mold forming method and an earth and sand mold forming apparatus used to construct a concrete structure such as a sabo dam.

In concrete structures such as sabo dams, as a form of super hard-mixed concrete (RCC: Roller Compacted Concrete), the earth and sand formwork is formed by compacting the local earth and sand at the construction site of the concrete structure. A concrete structure is constructed by placing concrete using a formwork.
In the conventional earth and sand mold forming, as shown in FIG. 1, the local earth and sand 2 are piled up on both sides in the width direction of the concrete structure 1 to be constructed, and are compacted in parallel to the longitudinal direction of the concrete structure 1. A pair of earth and sand molds 3 and 3 are formed. This earth and sand mold 3 has a slope 3a inclined at a constant gradient on the side surface on the concrete placing side.
Concrete 4 is placed and compacted in a flat inverted trapezoidal space formed by such a pair of left and right earth and sand molds 3 and 3. Next, the next earth and sand molds 3 and 3 are formed on the flat upper surfaces of the earth and sand mold 3 and the concrete 4 in a state in which the interval is narrowed, and the concrete 4 is placed in the space between the left and right earth and sand molds 3 and 3. And tighten. A concrete structure is constructed by sequentially repeating the formation of the earth and sand mold 3 and the placement and compaction of the concrete 4 as described above.

Conventionally, in order to form the earth and sand mold 3 having such a structure, as shown in FIG. 1, a dedicated bucket 8 for shaping a slope is provided at the tip of an arm 7 of a traveling construction machine 6 such as a backhoe. The top surface 3b and the slope 3a of the earth and sand mold 3 are struck by the lower surface of the bucket 8 (see Patent Document 1).
