Not limited to 0, an auger or the like for crushing earth and sand may be provided, and an apparatus capable of crushing earth and sand may be used.

This sorting work is carried out for each section shown in FIG. 1, and the earth and sand excavated from the site within the section are sorted into three stages by particle size by using the debris sander 30 having the above construction. That is, as shown in FIG. 4 (A), the earth and sand excavated from the section 12 are soil 40 having a particle size of 5 mm to less than 50 mm and soil 4 having a particle size of 0 mm to less than 5 mm.
2, and the soil 41 having a particle size of 50 mm or more is sorted and placed in the adjacent compartments such as the compartment 14 and the like. Then, FIG.
As shown in (B), the soil 40 having a large particle size is backfilled in the excavation hole of the section 12. The soil 41 having a particle diameter of 50 mm or more is carried out of the site of the baseball field 10. Alternatively, this soil 41 is crushed by a crusher or the like, and the soil 40 or 4 of less than 50 mm is crushed.
If used together with 2, it will promote effective use of resources and
It is possible to minimize the carry-out items outside the site. Next, as shown in FIG. 4C, the soil 42 having a small particle size is replaced with the soil 40.
When the soil 42 is filled up with a gradient of a predetermined size on the soil 42 and the grading of the section 12 is completed, the next section 14 and the like are subjected to the same procedure as described above as shown in FIG. 4 (D). Landslide one by one. In addition, anything other than gravel, that is, 50 mm
The above-mentioned foreign matters such as stones, concrete debris, roof tile fragments and glass fragments are carried out of the premises of the baseball field 10. This amount is usually 10% or less of the earth and sand on the site. Further, the same amount of supplementary material may be carried in depending on the amount of foreign matter carried out.

The sorting work is performed for each section shown in FIG. 1, but the present invention is not limited to this. After the backfilling work for the entire site of the baseball field 10 is completed, the slope set for each section is set. The surface layer of the baseball stadium 10 made of the soil 42 may be leveled so as to provide the ground.
