step 5, connecting the lower end of the transverse moving oil cylinder with a connecting lug plate B through a pin shaft, operating the transverse moving oil cylinder to extend out, and operating the transverse moving inner sleeve to extend out towards a steel lining A block, so that the steel lining A block rotates by a distance B from a point E on the steel lining A block as a circle center to a point F and is tightly attached to the surface of a concrete duct piece on the side part of the tunnel, and fixing the steel lining A block;
step 6, continuing to operate the auxiliary oil cylinder to extend out, so that the supporting arm extends out, the steel lining A block rotates by taking the point F as the circle center, and after the point E moves for a distance G, the top of the steel lining A block is tightly attached to the surface of the tunnel concrete pipe sheet;
step 7, temporarily fixing the steel lining A block and the concrete pipe sheet by adopting expansion bolts through connecting holes which are preset on the steel lining A block and the concrete pipe sheet;
step 8, operating the transverse moving oil cylinder to retract until the transverse moving inner sleeve is completely retracted to a middle position, removing a connecting pin between the telescopic outer sleeve and the transverse moving oil cylinder, and manually retracting the telescopic outer sleeve to the shortest outward direction;
step 9, operating the auxiliary oil cylinder to enable the auxiliary oil cylinder to be completely retracted and retracting the supporting arm;
step 10, starting a hydraulic motor with a brake, and enabling the steel lining mounting system to rotate clockwise by a degrees to an initial position, namely a middle position, under the drive of a chain;
step 11, operating the lifting oil cylinder to retract until the lifting system is completely lowered to the minimum;
the installation of the steel lining A block is finished;
similarly, reversely operating, installing a steel lining B block, and connecting the lower end of the transverse oil cylinder with the C connecting lug plate through a pin shaft when the steel lining B block is installed in the step 5;
finally, installing a steel lining C block, and in the step 1, respectively connecting a lifting point D, E of the steel lining C block with a lifting arm end on the flat car by using a pin shaft, lifting the steel lining C block by using a lifting device and placing the steel lining C block on a support wheel of a steel lining installation system;
step 2, connecting the connecting lug plate on the steel lining mounting system with a lifting point D, E of the steel lining C block;
step 3, operating the lifting oil cylinder to extend until the steel lining C block positioned on the lifting system reaches the surface of the concrete pipe sheet at the top of the tunnel and is tightly attached to the surface of the concrete pipe sheet at the top of the tunnel;
step 4, temporarily fixing the steel lining C block and the concrete pipe sheet by adopting expansion bolts through connecting holes which are preset on the steel lining C block and the concrete pipe sheet;
step 5, operating the lifting oil cylinder to retract until the lifting system is completely lowered to the minimum;
at the moment, the installation of the steel lining C block is finished;
completing the installation of the ring steel lining;
after the steel lining assembly is installed, the joint of the steel lining A block and the steel lining B block is welded, the joint of the steel lining B block and the steel lining C block is welded, and finally the steel lining A block, the steel lining B block and the steel lining C block are firmly connected by adopting chemical bolts.
