The invention discloses a dual-power tube pushing machine. The machine comprises two propelling mechanisms, the same pipe holding base is arranged on the two propelling mechanisms, the pipe holding base comprises a fixed base, the fixed base is connected with the two propelling mechanisms at the same time, a pipe penetrating through hole is formed in the fixed base, the hole center line of the pipe penetrating through hole is parallel to the propelling direction of the propelling mechanisms, a clamping pipe holding cylinder is arranged in the pipe penetrating through hole, the hole center lineof the clamping pipe holding cylinder is parallel to the hole center line of the pipe penetrating through hole, a wedge mechanism is arranged between the outer cylinder wall of the clamping pipe holding cylinder and the fixed base, and when the clamping pipe holding cylinder and the fixed base axially and relatively move, the wedge mechanism enables the clamping pipe holding cylinder to radiallyshrink inwards. A hydraulic motor is adopted to serve as pipe pushing power, the wedge mechanism is adopted for clamping a pipeline, and the obvious technical effects of reducing equipment manufacturing cost and manufacturing difficulty, and reducing device size are achieved.
