To provide a small-scale continuous wall construction method and a water seal device used therefor capable of fully placing concrete even to the joint portions of the continuous wall, eliminating concrete portions defectively placed and improving waterproof performance.
In a small-scale continuous wall construction method for building an underground continuous reinforced concrete wall, a groove for water seal plate is notched in a longitudinal direction over a whole length in the length direction of the surface, a water seal plate 7 equipped with a stopper portion in the middle of the groove for water seal plate is connected to the groove for water seal plate, a pair of locking pipes 3, 4 are provided by extending plate members 14, 15 for preventing the moving-round of the poured concrete at both the sides of the water seal plate, and these locking pipes are driven in such a manner that the water seal plates and plate members face each other in the longitudinal groove and the tip portions of the plate members come into contact with the wall of the longitudinal groove.
