STEEL PLATE IMPERVIOUS WALL, JOINT PART PROTECTIVE BODY, AND METHOD OF CONSTRUCTING THE STEEL PLATE IMPERVIOUS WALL

摘要

A steel plate impervious wall with excellent imperviousness and workability, a joint part protective body, and a method of constructing the steel plate impervious wall, the steel plate impervious wall (1) comprising a steel plate (2) having joint parts (22) manufactured by bending one sheet of steel plate (2) near both end parts in a generally cylindrical shape so as to form clearances between the bent parts and the end sides of the steel plate (2), bottom covers (3) installed at the lowermost ends of the joint parts (22), characterized in that a small diameter joint part (222) and a large diameter joint part (221) are formed by forming the joint parts (22) so that the inner diameter of one joint part (22) is formed larger than the outer diameter of the other joint part (22) to insert the small diameter joint part (222) of the steel plate (2) installed adjacent to the other steel plate (2) into the large diameter joint part (221) of the steel plate (2); the method comprising the step of inserting the steel plate (2) into excavated grooves (7) filled with solidifying material (4). When the installation of the steel plate (2) adjacent to the other steel plate (2) is temporarily stopped, the joint part protective body (5) is fitted to the large diameter joint part (221) of the steel plate (2) positioned at the final end.
