In the construction of a tunnel by a shield method, slag is discharged in the construction of a soil pressure balance shield, and a belt conveyor is adopted to convey the slag into a slag car; for slurry balance shield construction deslagging, hose reels or hydraulic steel sleeves are adopted for extension. However, in the construction of the shield method connecting channel, the shield main machine and the rear matched trolley are designed separately, the shield main machine continuously moves forward along with the assembly of the lining, and the matched trolley stays in the tunnel and does not move forward along with the shield main machine to enter the connecting channel, so that the existing slag discharging mode in the construction of the shield method tunnel cannot be suitable for the construction of the shield method connecting channel; the belt conveyor is of a fixed length and cannot be suitable for a continuously prolonged muck running line; the hose reel is for transporting liquid and is not suitable for transporting the flow plastic slag; although the hydraulic steel sleeve can be extended, the extension proportion is smaller, repeated extension is needed, and the hydraulic steel sleeve cannot adapt to the working rhythm of the shield main machine.
