This invention provides a digging and flushing device for a submerged shaft boring machine. The cutting head is driven to rotate within a housing, using its surface cutting teeth to break up the rock and soil at the bottom and walls of the shaft. A slurry pump is mounted on the housing. By placing a first flushing component at a first predetermined position between the slurry pump inlet and the cutting head, and a second flushing component at a second predetermined position after the cutting head has rotated past the slurry pump inlet, the first flushing component performs high-pressure flushing in the suction chamber area where soil is first generated and most prone to adhesion. This disrupts the adhesive structure of the soil at its source, preventing it from adhering to the cutting head surface and forming mud cakes. Even if a small amount of soil is not flushed away by the first flushing component, the second flushing component performs secondary cleaning within the digging chamber, further reducing the risk of mud cake formation. This dual flushing mechanism significantly improves the adaptability of the cutting head in strata prone to mud cake formation, such as argillaceous clay and silty mudstone. The synergistic effect of both components achieves full-process flushing coverage for each rotation cycle of the cutting head.

And when the third section is blocked, high-pressure water of the third flushing pipeline can effectively flush away blockages regardless of a siphon closestool or a direct flushing closestool, so that the problem of blockage is solved.
