The working principle of the heading mechanism will be described below by taking the pushing assembly 1 on the center ring cutter head 7 as an example. Since the left and right side motions of the pushing assembly 1 are identical, the excavation process of the center ring cutter 7 will be described by taking only the left side motion as an example.
In the initial state, the pushing cylinder 61 and the left pushing cylinder 63 on the steel pipe ring 6 are in the contracted state, and the left press block 21 is in the fixed state under the action of the left spring 22 and the left positioning block 31. At this time, the left spring 22 is in an original long state or in a slightly compressed state, supports the longitudinal elastic member 33 of the movable portion 2, and is in a compressed state by the gravity of the movable portion 2.
In a specific embodiment, the movable part 2 is a clearance fit with the fixed part 3, and the movable part 2 is vertically positioned by means of a longitudinal elastic member 33 mounted to the fixed part 3.
At the beginning of the movement, the pushing cylinder 61 mounted on the steel pipe ring 6 drives the cylinder box 62 to move downwards, which contacts the beam 24 and gradually pushes the movable part 2 downwards. When the left pressing block 21 is pushed out by a certain distance (the pushing distance is greater than the preset depth of the cutter), the pushing oil cylinder 61 stops acting, and the left pushing oil cylinder 63 arranged in the oil cylinder box 62 pushes the left pressing block out; when the left press block 21 contacts the left stopper 23, the left push cylinder 63 stops, the push cylinder 61 starts to contract, and the movable portion 2 moves upward under the elastic force of the longitudinal elastic member 33.

Meanwhile, the jacking cylinder 61 is fully retracted, and the cylinder box 62 is driven to return to the initial state again. At this time, only the cutter of the center ring cutter head 7 in the cutter head is in contact with the excavation surface, so the driving part 5 only needs to drive the center ring to perform excavation.
