PURPOSE:To form a sheathing continuous wall capable of completely stop water by a method in which grooved guiders are provided over the whole lenght of the sides of a cylindrical main part, and a projected line portion to be guided, having a T-shaped cross section, is provided on the opposite side of the grooved guiders. CONSTITUTION:A grooved guider 12 is provided over the whole lenght in the axial direction of a cylindrical main part 11 consisting of a steel pipe of an outside diameter of 100-600mm. and a rolled plate, and also a projected line portion 13 to be guided, having a T-shaped cross section, is provided over the whole length on the opposite side of the grooved guider 12. In forming a sheathing continuous wall, vertical holes 1A are excavated on a projected line C, most preceding sheathing part 10A is penetrated into the hole 1A, and the next sheathing part 10B is et into the hole 1B while inserting the projected line 13 into the guider 12 of the preceding sheathing part 10A. In the same way, sheathing parts 10C-10N are erected into the holes 1A-1N to form a continuous wall.
