The tideland which the sludge accumulates the hydrophilic improvement mannered null rivers

摘要

PPROBLEM TO BE SOLVED: To improve the hydrophilic property of a tideland in a river by utilizing the soil, which is obtained by dredging or the mud on its bottom dug up for a percolation column produced when restoring the tideland, as a sand covering material for making effective use of waste and restore the improved tideland so as to obtain such firmness that allows a person to walk on the tideland at the same time. PSOLUTION: In this hydrophilic property improving method for the tideland, a stream of river water is formed between an underground sand layer and a surface layer in the river rs, the percolation column 1 made of lime ash granulated particulates is inserted into the riverbed rb and the tideland rf where organic mud is accumulated to supply oxygen into the mud accumulated on the riverbed rb, and the soil dug up when drilling an intrusion hole 3 at the construction work site when inserting the percolation column 1 is mixed with the lime ash granulated particulates to produce the hydrophilic soil structural material, which is spread all over the tideland rf in which the percolation column 1 is inserted as the sand covering material 2.
