PURPOSE:To efficiently erect underground continuous wall by a method that, after preventing adherence of slime by covering horizontal reinforcements of reinforced cages for a preceding panel with protective plates, the reinforcements are set so as to lap with horizontal reinforcements of reinforced cages for a succeeding panel, and concrete is placed. CONSTITUTION:After reinforced cages 10A for the preceding panel 10 are set in a preceding excavated ditch 35, the preceding panel 10 is made by placing concrete. Then, projected horizontal reinforcements 13A of the cages 10A are covered by setting the protective plates 22 to the end of the panel 10. After a succeeding ditch 40 is excavated, the end of the panel 10 is cleaned in pulling up the protective plates 22. The reinforced cages 11A for the succeeding panel are set in the succeeding excavated ditches 40 so that the horizontal reinforcements 13B lap with the reinforcements 13A of the cages 10A of the panel 10. Then, the succeeding panel 11 is built by placing concrete. |
