The invention relates to a shield entry spring hinge plate sealing device, which is an annular device and is arranged on the inside wall of a receiving well close to one side of a tunnel portal of an entry. The axis of the device is overlapped with the axis of the tunnel portal of the entry. The device comprises a steel ferrule, a rubber ring and a plurality of telescopic components, wherein the steel ferrule comprises an annular bottom plate; an annular side wall is formed by encircling the periphery of the annular bottom plate; the annular bottom plate is fixedly arranged on the inside wall of the receiving well, and the inner ring surface of the annular bottom plate is larger than the outer ring surface of a shield machine; the rubber ring is sandwiched between the inside wall of the receiving well and the annular bottom plate, and the inner ring surface of the rubber ring is smaller than the outer peripheral surface of the shield machine; the plurality of telescopic components are uniformly distributed on the steel ferrule along the circumference; each telescopic component comprises a hinge plate and an air spring; the first end and the second end of the hinge plate are hinged to the first end of the annular bottom plate and the first end of the air spring respectively; and the second end of the air spring is hinged to the annular side wall. By matching the rubber ring with the telescopic components, a shield shell and a segment of the shield machine are tightly pressed to achieve a sealing effect in the shield tunneling and leaving process, so that the water and mud leakage phenomenon in a tunnel ring is avoided.
