Segmentation system for preventing sludge blockage in slurry shield tunneling machine

The invention discloses a cutting system for preventing sludge blockage in a slurry shield tunneling machine, which is arranged in the slurry shield tunneling machine and comprises an in-bin cutting structure and an in-pipe cutting structure, the in-bin cutting structure is arranged in a residue soil bin and is positioned at the lower part of the residue soil bin, and the in-pipe cutting structure is arranged in a residue discharge pipe. According to the in-bin dividing structure, deposited and caked muck in the muck bin is divided, and the situation that the muck is deposited at the bottom of the muck bin, the whole muck bin is blocked, and then normal discharging of the muck is affected is avoided; the cutting structure in the pipe is used for cutting the sludge blocks entering the deslagging pipe, so that the situation that the large-size sludge blocks are formed again to block the deslagging pipe is avoided, and the situation that the normal deslagging operation is affected due to deposition at corners an
