SOIL LAYER STRUCTURE AT RECLAIMED LAND NEAR SEASIDE FOR PLANTATION

摘要

The present invention relates to a soil layer structure for creating an environment suitable for plantation in a soil containing high-concentration salt such as a seaside reclaimed land. The soil layer structure according to the present invention includes: a downward drainage body inserted into a soil on a lower side from an inner surface of a pit and having an inner pore along a length direction, the pit being formed by digging of the soil containing high-concentration salt; a capillary lifting prevention layer buried in a bottom surface of the pit and preventing inflow of salt-containing water from below that is attributable to a capillary phenomenon; a soil layer placed on the capillary lifting prevention layer and formed from pit-filling soil; and a first blocking layer interposed between the soil layer and the capillary lifting prevention layer so that filling of the pore in the capillary lifting prevention layer with the soil layer-forming soil is prevented.
