Preferably, the rough place on the predicted forward line of the shield machine is adjusted in advance, so that the moving stability of the shield machine is ensured.
And a second step of: translation and preparation before stepping. The shield body of the shield machine is pushed to the receiving table in an empty mode, then brackets positioned on the left outer side face and the right outer side face of the receiving table are welded on the left side and the right side of each shield body, and meanwhile a jacking oil cylinder is arranged below the brackets. In order to ensure that the shield machine and the receiving table can be lifted together when the lifting oil cylinder works, welding points are also arranged at the contact positions of the shield machine and the receiving table.
And a third step of: the shield machine translates and steps through the station.
(1) And (5) the shield machine initially moves transversely. Firstly jacking up the shield machine through a jacking oil cylinder, paving a transverse moving track below a receiving table and on the side face of the receiving table, enabling the direction of a universal wheel to be consistent with the direction of the transverse moving track, retracting the jacking oil cylinder after the transverse moving track is paved, enabling the universal wheel to fall on the transverse moving track, hinging the other end of a stepping oil cylinder on the side face of the receiving table, enabling one end of the stepping oil cylinder to be propped against a self-provided counter-force support on the side face of the shield machine, and enabling the stepping oil cylinder to work so that the shield machine translates to the middle of a transition section of a corresponding platform.
(2) The shield machine is initially stepped.

In the third step, the right line shield machine line moves, the initial traversing distance is 1475mm, the initial stepping distance is 16m, the secondary translating distance is 6.775m, the right line shield machine starts to stop after stepping for 60m in the secondary stepping, then the left line shield machine starts to step in sequence, the left line shield machine stops after stepping for 40m in the secondary stepping, and after the rear template trolley is removed, the two shield machines continue to step synchronously. In the shield machine station crossing, the transition center from 6.775m to the initial hole is transversely shifted, the transition center from 16m to the initial hole is stepped, and finally the transition center from 1.475m to the initial position is transversely shifted, so that the secondary initial operation is ready to start.
