CONSTITUTION:Frame parts 3 and 3' having a nearly ?-shaped form and legs 4 on its lower sides are set in place, and holding frames 1 and 1' and 2 and 2' are attached to the sides of the upper and lower parts of the frame parts 3 and 3', respectively. Under the condition, a sheet pile A can be stably set under the guidance of the holding frames 1 and 1' and 2 and 2'. The sheet pile A thus set can play the part of holding part for another sheet pile and therefore, the frame parts can be removed. |
