Method for intensification of releasing of stuck pipe string freezing according to which over zone of freezing one forms wave pulses that are transferred to bottom of pipe string, due to that release of those takes place. To increase effectiveness of use of energy of impact for pulse-wave effect at zone of pipe string freezing one creates additional pulse-wave effect on freezing zone due to fact that wave pulses propagating to the upper part of pipe string come to rod of additionally installed unit, are transferred to disk springs, those reflect and direct them to bottom of pipe string. For realization of method one uses appliance for intensification of releasing of stuck pipe string, this is installed over jar and has body, rod and springs. To increase effectiveness of operation of the unit inside body movable pipe with rods is installed, there separated with springy element packs of disk springs with deformation restrictors forming gaps with inner wall of the body are placed.
