PROBLEM TO BE SOLVED: To provide a wall body structure enabling the easy construction of a long double wall structure with high execution accuracy without making a wall-body component member driven for penetration into a mound. SOLUTION: The wall body structures 1, formed of rectangular cylinder- shaped box bodies 2, are disposed on the mound G in such a manner as to be adjacent to one another, for the purpose of constructing the long double wall structure. The box body 2 is framed for formation so as to have a hollow space 8 by being joined by a pair of both front and rear side walls 3 and 4 facing each other, both right and left retaining walls 5 and 6 facing each other, and a corner member 7. The side walls 3 and 4 and the retaining walls 5 and 6 are formed by joining many side wall component members 31 and 41 and retaining wall component members 51 and 61, and a packing material 9 is infilled into the hollow space 8 to a given height.
