The invention discloses a lifting pile. The lifting pile comprises a base barrel used for being buried underground, a telescopic pile stretching out of or retracting back into the base barrel, a pulling unit used for pulling the telescopic pile to retract back into the base barrel or release the telescopic pile to stretch out of the base barrel, and a jacking unit used for storing energy when thetelescopic pile retracts back into the base barrel and releasing energy when the pulling unit releases the telescopic pile so as to jack the telescopic pile out of the base barrel. By the adoption ofthe above technical scheme, the structure is simple and reliable, and the effect that the burying depth of the base barrel is further reduced can be achieved. 本发明公开了种升降桩，包括基筒，其用于埋设于地下；伸缩桩，其从基筒伸出或缩回；牵拉单元，用于牵拉伸缩桩缩回基筒或释放伸缩桩以使其得以伸出基筒；顶升单元，用于在伸缩桩缩回基筒时储能，并在牵拉单元释放伸缩桩时释能将伸缩桩顶出基筒。上述技术方案结构简单可靠，进步地且能实现减少基筒埋设深度的效果。
