PURPOSE:To prevent a row of piles from inclining and falling by driving a plurality of piles continuously under the ground, and driving piles in connection with existing piles into a space from which metal fittings are removed after connecting piles to the correction metal fittings connected to the existing piles of the tips to drive again. CONSTITUTION:Steel sheet piles P1 - P5 are force-fitted under the ground by a pile force-fit drawing machine A so that they are slightly fallen backward. Then, the steel sheet pile P5 is force-fitted in a state of falling slightly forward, and if the correction is required, a grip of a correction metal fittings 11 is interlocked with a grip of the steel sheet pile P5 to insert the fittings 11. After that, a steel sheet pile P7 is interlocked with a grip of the other end of the metal fittings 11, and after force-fitting, steel sheet piles P8 - P10 are successively force-fitted under the ground. The drawing machine A is withdrawn to put it on the upper end of the steel sheet pile P8 - P10, the steel sheet pile P7 is pulled out, and the metal fittings 11 is pulled out. Further, the steel sheet pile P7 is force-fitted again, and a new steel sheet pile is force-fitted into a space from which the metal fittings 11 is pulled out.
