Abstract
PURPOSE: To prevent the consolidation of soil and sand between a casing and the already constructed pile by driving a casing with an opened window into around the already constructed pile to enable the pile to be drawn out by shutting from the friction between the pile and the surrounding ground.
CONSTITUTION: The cylindrical casing 2 with the opened window 1 is driven in the ground by a vibro-pile hammer in such a way as to cover the already constructed pile 3 inwardly. Then, through the opened window provided in the casing 1, the soil and sand 5 between the casing 2 and the pile 3 is led to the ground 4 outside the casing 2, and then the pile is drawn out by a crane. Thus, the pile can be easily drawn out because no consolidation of the soil and sand 5 occurs and the friction is shutted from between the pile and the surrounding ground. Also, the pile can be drawn out by injecting a fluid into the inside of the casing.
