Landing method by coral gravel accumulation, permeation structure and structure therefor

摘要

PROBLEM TO BE SOLVED: To provide an emergence method utilizing coral gravel accumulation, and a permeable structure and a structure for the same.SOLUTION: An emergence method utilizing coral gravel accumulation is a method for achieving emergence by accumulating coral gravel. A permeable structure 10 having a plurality of openings 13 capable of capturing the coral gravel 1 is installed in the direction of enabling the passage of a water mass. The coral gravel is accumulated by capturing the coral gravel in such a manner as to make the water mass pass through the openings of the permeable structure.SELECTED DRAWING: Figure 1
