PROBLEM TO BE SOLVED: To easily secure the continuity of steel wall connecting member in a cross part in the case of inserting the steel wall connecting member into the underground continuous walls provided in two directions and crossing to each other in order to improve the proof stress. SOLUTION: After constructing the underground continuous wall 1 in one of two directions crossing each other to a part in this side of a crossing part 30 crossing the underground continuous wall 2 provided in the other direction, an enlarged width wall 3 continued to the underground continuous wall 1 and having a wall thickness larger than that of the wall 1 is constructed to a position crossing the underground wall 2 provided in the other direction.
