The invention relates to the technical field of shield tunneling machine equipment, in particular to a shield tunneling machine special for soft stratum construction, which comprises a shield tunneling machine main body, an annular seat is welded on the side surface of the shield tunneling machine main body, an annular groove is formed in the outer side surface of the annular seat, and limiting grooves are symmetrically formed in the side wall of the annular groove; the tunnel reinforcing device has the beneficial effects that through movement of the arranged shaking mechanism, the curved surface block pushes the limiting block to move upwards, the limiting block pushes the whole reinforcing mechanism to move upwards, the reinforcing plate extrudes the side wall of a tunnel, the side wall of the tunnel is fixed, the side wall of the tunnel is fixed, and the side wall of the tunnel is fixed; therefore, the side wall of the tunnel is reinforced, and the stratum of the side wall of the tunnel is prevented from f
