1. A method for generating a non-harmonic oscillations for driving and extracting the pile elements and the tongue, characterized in that the duration of the loading and unloading phases are different due to the difference of the vibrator speed up and its speed down within one cycle of oscillation, which is achieved by rotating the pair of rollers with unbalance having a larger static torque at an angular velocity twice lower rotational speed with the unbalance shaft pairs having smaller static moment, while the ratio of static variables eskih different pairs of points is 8 and the initial phase setting unbalances different pairs of identical, or differ by 180 ° in different modes of plant operation that determines the difference speeds up or down within one tsikla.2. A method for generating nonharmonic vibrations for driving and extracting the pile elements and the tongue, characterized in that the magnitude of the driving force, generating downward movement and the magnitude of the driving force, generating upward movement vary within a single cycle of oscillation, which is achieved by rotating the pair of rollers with unbalance having greater static Currently with the angular velocity twice lower rotational speed with the unbalance shaft pairs having smaller static moment, the magnitude relationship of the static moments of different n ap is 16, and the initial phase position of the unbalanced masses with a large static torque to be different from the location of the phase unbalance smaller eccentric moment to 45 ° or by 135 ° in different modes of plant operation, which determines the direction of action greater driving force: up or down within a tsikla.3.
