PURPOSE: A pile set system for recovering a lost bank is provided to shorten the time required for restoration by deeply piling into the ground of a bank using a pile set composed of many piles instead of a free-falling pile and to minimize the loss of lives and properties by restoring the lost bank in the early stage rapidly using a pile set. CONSTITUTION: The pile set system for recovering a lost bank comprises: a pile set composed of many piles(20) to stop the lost of a bank in the first stage; and a helicopter lifting up the pile set to the appointed height and free-falling the pile set from the appointed height using potential energy. The pile set for the lost bank recovery is formed by the one-dimensional arrangement of many piles(20) used for the lost bank recovery, and a pile joiner(21) is used between piles and made of solid materials to keep the shape of a pile set if a pile set falls from the appointed height and drives into the ground of the lost bank.
