The invention belongs to the technical field of pipe jacking guide rolling, and particularly discloses a loss-reduction self-compensation type guide rolling machine for small-caliber pipe jacking construction, which comprises a shear fork type lifting seat, a loss-reduction type guide rolling device and a self-compensation type fixed docking mechanism. According to the situation that when the small-caliber jacking pipe rolls in a guiding mode, the outer wall is prone to being damaged by soil and gravel adhering to the outer wall, the technical effect of removing the soil and gravel adhering to the outer wall of the small-caliber jacking pipe in an air-flowing mode is achieved only through rolling force during guiding rolling under the condition that no external energy source exists; in order to facilitate subsequent butt joint between the small-caliber jacking pipes, a self-compensation type fixed butt joint mechanism is arranged, and the technical effect of stable butt joint of small-caliber pipelines in any
