PURPOSE:To simplify the drawing work of steel sheet piles for sheathing as well as raise the economical advantage of the work by a method in which a steel sheet pile is pulled out by an adequate length while pressing the steel sheet pile and the surface of the adjacent ground by a press plate, the steel sheet pile is again penetrated into the ground, and the steel sheet pile is orderly drawn out while tamping broken soil into the voids of the ground. CONSTITUTION:A press plate 3 is laid on the ground's surface 2 adjacent to a sheet pile 1, soil is pressed downwards, the sheet pile 1 is pulled up by an adequate length and again penetrated into the ground, and the sheet pile is orderly drawn out while tamping broken soil 5 into voids 4 formed in the drawing work. |
