METHOD OF CONSTRUCTION FOR THE LOST BANK RECOVERY IN THE FIRST STAGE RAPIDLY BY A FREE-FALLING PILE USING POTENTIAL ENERGY AT THE APPOINTED HEIGHT

摘要

PURPOSE: A method of construction for the lost bank recovery using a free-falling pile is provided to minimize the loss of lives and properties by restoring the lost bank in the first stage and constructing a pile structure composed of a free falling pile or many piles deeply to the ground of a bank not to be carried away by the speedy current. CONSTITUTION: The method of construction for the lost bank recovery using a free-falling pile(20) comprises: a weight pile(20) formed in the shape of a column whose length for preventing the lost of a bank(11) is twice as long as the height of a bank and the lower diameter is shorter than the upper diameter; and a helicopter(30) lifting up the pile(20) above the appointed height and piling to the ground by free-falling the pile(20) from the appointed height using potential energy.
