The invention relates to fundamental construction, in particular to a pulling-out method of underground piles. A pulling-out method of underground piles by sleeving, vibrating and punching is characterized by including the following steps: firstly, a sleeve is made, a long steel pipe is used as the sleeve, the external wall of the long steel pipe is provided with a water pipe and a ventilating pipe, one end head of the long steel pipe is in a sawtooth shape, and the internal wall of the long steel pipe is provided with a steel wire; secondly, the pile head position of an underground pile is determined, and soil is removed and backfilled; thirdly, a steel sleeve is vibrated and sunken, a caterpillar-band hoist is used for hanging a vibrating hammer to vibrate the sunken sleeve to enable the sleeve to sleeve the underground pile, and after the sleeve is positioned, the vibrating hammer is removed; fourthly, the pile is pulled out, after the sleeve sleeves the pile completely, the caterpillar-band hoist is used for contracting the steel wire to hoist; fifthly, the steel sleeve is pulled out by vibrating, the vibrating hammer is started up, and the caterpillar-band hoist is used for hoisting to pull out the steel sleeve with vibrating; and sixthly, a pile hole is levelly filled, and a disturbing area is processed. The invention can successfully pull out underground piles to remove the obstacle for construction.
