secondly, pouring and forming the top surface of the section of the tunnel by using a second lining trolley (4), pouring and forming the bottom surface of the next section of the tunnel by using an inverted arch form trolley (2), and performing interference-free excavation at the front end of the tunnel;
thirdly, the second lining trolley (4) retracts the mould, so that the second lining template is separated from the top surface of the tunnel; the self-propelled trestle (1) drives the two lining trolleys (4) to simultaneously move forwards to a work area on the inverted arch template trolley (2) after construction is finished, or the two lining trolleys (4) actively move to the work area on the inverted arch template trolley (2) after construction on the self-propelled trestle (1);
fourthly, the inverted arch template trolley (2) drives the inverted arch template (3) to move to the next working area for construction;
and fifthly, circulating to the first step until the tunnel construction is completed.
