BOTTOM-CLINGING GROUND SUBSTANCE STRUCTURE FOR MAKING SEAWEED BED AND METHOD FOR INSTALLING THE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide both a bottom-clinging ground substance structure for making a soba seaweed bed capable of settling marine algae and organisms by setting a bottom-clinging ground substance structure having a low ground pressure on the bottom of the sea of silt soft ground on which no marine alga settles and furnishing the structure with a seaweed bank plates on which marine algae and organisms can settle and a method for installing the bottom-clinging ground substance structure. SOLUTION: This bottom-clinging ground substance structure 1 for making a soba seaweed bed exhibits a trapezoidal shape as a whole on a side view and is provided with multistage incision parts 2 from both the sides of the trapezoidal shape so as to form seaweed bed making bodies 6 in the height direction of the trapezoid. Both the top faces of the seaweed bed making bodies 6 constituted in a multistage form are provided with seaweed bank plates 3, respectively.
