Segment lofting and steel plate mounting process

The invention belongs to the technical field of tunnel construction processes, and particularly relates to a segment lofting and steel plate mounting process. The process comprises the following steps that according to the construction path deflection and deviation correction requirements, a proper standard ring and a lining ring are selected; according to the interval curve trend, the segment width and the segment position parameters are determined, and the size parameters of all blocks in the annular direction of the standard ring and the wedge-shaped ring are determined; pre-typesetting is carried out according to the interval curve trend; according to the lining ring splicing requirement, the segment block stacking number and the site construction area limitation in the pre-typesetting result; splicing and configuration of special segments; and splicing and configuration of negative ring segments. The invention aims to provide the segment lofting and steel plate mounting process which can improve the exis
