<p>PROBLEM TO BE SOLVED: To provide a filler for artificial loan, which can prevent grains of the filler from dispersing and flowing out and can sufficiently secure impact absorptivity and water permeability, and an artificial loan using the same.SOLUTION: A mixture consisting of first grains 3a having grain diameters of 50 to 18 mesh, second grains 3b having grain diameters of 280 to 70 mesh, and hard balls 3c having diameters of 0.8 to 1.2 mm used as a filler 3 filled between piles 2. Thereby, the first grains 3a and the second grains 3b are moderately consolidated and the filler 3 is prevented from dispersing and flowing out due to wind and rain, and the filler 3 is prevented from being perfectly consolidated by the hard balls 3c. Consequently, impact absorptivity and water permeability by the filler 3 can be sufficiently secured.</p> |
