RAIN WATER STORAGE INFILTRATION FACILITY USING TABLE-LIKE UNIT MEMBER HAVING DOUBLE LEGS

摘要

PROBLEM TO BE SOLVED: To propose a new method to use a unit member having double folded legs.SOLUTION: Large and small concave parts are generated between facing unit members when the table-like unit members, each of which has a board body, legs opening to the board body, and double legs having legs further extending from holes formed on the bottoms of the legs toward the board body, are disposed so that the legs or the board bodies face each other. A rain water storage infiltration facility according to this invention uses the table-like unit members having double legs, and makes use of a storage space formed by connecting large and small concave parts generated between the unit members with a column member of a size capable of being inserted in the concave part.SELECTED DRAWING: Figure 1
