The invention relates to a transporting method and structure for tunnel construction through a shield method. The transporting method comprises the steps that a locomotive rail is laid on a segment atthe bottom in a tunnel, and one end of the locomotive rail extends into a shield vehicle frame; a pi-shaped piece is erected on the part, close to the other end of the locomotive rail, of the segmentat the bottom in the tunnel and extends to the position close to a working well, and a plane is formed in the top surface of the pi-shaped piece; a construction material is transported from the working well into the tunnel through a car travelling on the plane of the pi-shaped piece; the construction material on the car is hoisted to a rail locomotive travelling on the locomotive rail; and the construction material is transported into the shield vehicle frame through the rail locomotive. The transporting method and structure for tunnel construction through the shield method have the beneficial effects that car transporting and rail locomotive transporting are combined, the advantages of the two transporting modes are exerted, and the transporting difficult problems under the small-clearance and large-slope working condition are solved.
