PROBLEM TO BE SOLVED: To provide a rigid structure continuous vertical wall that has a rigid structure comprising two or more wall forming steel sheets surrounding important facilities with a low maintenance cost, and can maintain an environment over a long term.SOLUTION: A steel continuous wall structure comprises two or more wall forming steel sheet piles 310. The wall forming steel sheet piles 310 are placed vertically to the ground and several pieces of piles are laterally connected at any angle and form the wall structure while defining a predetermined zone. In the lengthwise wall forming steel sheet piles 310, a pair of spiral fitting joints 320J spirally wound in a plan view toward the vertical lower part of both left and right edges is formed over a predetermined range in the longitudinal direction. The spiral fitting joints 320J of the adjacent wall forming steel sheets 310 are stacked and fitted in a spiral portion to each other and connected, and thereby the rigid structure continuous vertical wall of a state connected in a desired angle is formed. |
