PROBLEM TO BE SOLVED: To reduce the labor for construction while securing construction accuracy when the sidewall of an underground tank is constructed using a slip form. SOLUTION: When an underground wall 31 is constructed at a position corresponding to the outer periphery of the sidewall 21 and the inside of an underground continuous wall 30 is excavated, a guide column 40 is constructed at a position corresponding to the inside of the sidewall 21 in plan view, and the guide column 40 is connected to the underground continuous wall 30 with a connection member 41. While a slide form device 100 having a mold part 150 is raised by a climbing jack 130 with the horizontal movement thereof arrested by holding the guide column 40, concrete is placed between the underground continuous wall 30 and the mold part 150. Since the guide column 40 is connected to the underground continuous wall 30 and supported thereon, the construction accuracy can be secured. Since the guide column 40 is buried in the sidewall 21, the labor for removal is eliminated and the construction efficiency can be increased. COPYRIGHT: (C)2010,JPO&INPIT
