description The utility model provides a device for rapidly excavating a shield tunnel freezing construction connection channel, which belongs to the technical field of tunnel engineering and comprises a tunnel arch frame, a hydraulic arm, a spiral heading machine, a telescopic belt conveyor and an unearthing trolley. The hydraulic arm is telescopic and bendable; the spiral heading machine comprises a rack, a spiral cutter rotationally mounted on the rack and a driving mechanism for driving the spiral cutter to rotate; the tunnel lagging jack is supported in the tunnel and corresponds to the design position of the connecting channel; the fixed end of the hydraulic arm is installed on a tunnel arch frame, and the operation end of the hydraulic arm is connected with a rack of the spiral heading machine and used for adjusting the position of the spiral heading machine to enable the spiral heading machine to conduct heading along the designed position of the connection channel. The top end of the telescopic belt conveyor is
