The topsoil is laid down and leveled with bulldozers. At that time, the surplus soil is transported from the site to another location, where the surplus soil is disposed of, and topsoil with uniform gravel and particle size is carried in from outside the site. [0003] However, in the above method, it is necessary to rely on truck transport or the like to carry out the remaining soil or to bring in the topsoil having a uniform size of gravels and particles. It may lead to an increase in traffic volume, which may lead to environmental destruction. In addition, even if the topsoil with a uniform size of gravel is brought in from the outside, these gravel and soil use natural resources, so there is a shortage of good-quality gravel and soil as recently. Below, the cost is high. The present invention has been made in consideration of the above facts, and
It is an object of the present invention to provide a recycled clay method capable of effectively utilizing resources or reducing construction costs. [0005] A reclaimed clay method according to the present invention comprises a leveling step of digging up soil in a site to be laid and loosening the hard topsoil of the site, and following the leveling step, Excavating soil from the, the separation step of separating the soil by particle size, and, following the separation step, a backfilling step of backfilling the holes drilled for each of the separated soil,
It is characterized by having. According to the recycled clay method of the present invention, first,
In the leveling process, a cultivator is used to excavate the surface of the entire site to loosen hard topsoil. next,
In the separation process, soil is excavated from the site using excavation means,
The soil is separated for each particle size by a separation means. next,
In the backfilling step, the separated soil is backfilled into holes drilled for each particle size. [0007] Thus, it is possible to minimize the carry-out of the residual soil and the like and the carry-in of the gravel for the base and the soil for the surface layer, etc., and it is possible to carry out the land preparation work in the same site or in a narrow adjacent land. Therefore, it is possible to prevent environmental destruction and waste of resources due to the construction work. FIG. 1 shows a baseball stadium 10 constructed using the recycled clay method according to the present invention. The site of the baseball stadium 10 is provided with a slope for drainage of rainwater or the like (in FIG. 1, the direction of arrow A is shown as a downward slope direction). Also, the baseball stadium 10 is divided into a number of sections such as triangular sections 12, 14,... In plan view at the design stage of development, and the direction and angle of the gradient are set for each section. It is a configuration to do. In the present embodiment, the entire site of the baseball stadium 10 is divided into 16 sections. However, in practice, the section can be divided according to the area of the site, and each section is not limited to a triangular shape as shown in FIG. And other shapes can be applied.
