PURPOSE:To improve construction efficiency and economical efficiency, by a method wherein, after a reinforcing cage is built in a trench dug adjacent with a preceding unit wall in a manner that it is overlapped with an existing reinforcing bars in concrete, concrete using delay-cured cement is placed in the groove. CONSTITUTION:After a trench 22 is excavated adjacent with a preceding unit wall 15, a reinforcing cage 23 is built in a manner that the cage is overlapped with renforcing bars 18 in the unit wall 15 through engagement of a connection part 24 of the reinforcing cage 23 with a joint recess 20 of the unit wall 15. Thereafter, concrete 26 using delay-cured cement is placed through a tremie 25. Through repetition of the same process, a series of an underground continuous wall is constructed. |
