Shield tunnel lining segment reinforcing body auxiliary installation method

The invention relates to a shield tunnel lining segment reinforcing body auxiliary mounting method which comprises the steps that the inner contour of a shield segment and the contour information of a reinforcing body are obtained, mounting holes for mounting and fixing the reinforcing body to the segment are preset in the reinforcing body, and the mounting holes are in one-to-one correspondence with to-be-drilled positions on the shield segment; judging whether the assembly error after the reinforcing body is installed and fixed to the duct piece meets the requirement or not, and if not, adjusting the reinforcing body; duct piece structure information and tunnel interior appendage information are collected, and a drilling limiting area is determined; whether the position to be drilled on the shield segment conflicts with the drilling limiting area or not is judged, if yes, a reinforcing body is adjusted or an adjunct in a tunnel is migrated, and if not, an alignment base point is selected on the segment; and
