CONNECTION STRUCTURE OF SIDE PLATE MEMBERS OF CYLINDRICAL BODY FOR STORAGE INFILTRATION TANK, CYLINDRICAL BODY FOR STORAGE INFILTRATION TANK HAVING THE CONNECTION STRUCTURE, BOX BODY FOR STORAGE INFILTRATION TANK, AND METHOD FOR CONNECTING SIDE PLATE MEMBERS TO CONSTITUTE THE CYLINDRICAL BODY FOR STORAGE INFILTRATION TANK

摘要

PROBLEM TO BE SOLVED: To provide a connection structure of side plate members of a cylindrical body for a storage infiltration tank, which allows for easy connection.SOLUTION: The side edge parts 5 and 6 of side plate members 3 and 4 to constitute a cylindrical body 2 for a storage infiltration tank are provided with a displacement restricting part 11 and a displacement restricted part 21, and a slide engaging part 15 and a slide engaged part 25. The side plate members 3 and 4 are relatively displaced in a first direction perpendicular to the axis of the cylindrical body 2 so that the displacement restriction part 11 engage the displacement restricted part 21. The side plate members 3 and 4 are further relatively displaced in a second direction perpendicular to the first direction so that the slide engaging part 15 engages the slide engaged part 25, forming a connection structure 1 of the cylindrical body 2.
