Early-stage pipeline rearrangement method for subway tunnel

The invention discloses an early-stage pipeline row changing method for a subway tunnel, and the method comprises the steps: obtaining the type of a cable needing row changing, the tensile degree of the cable per unit length, the net distance between the pipeline and a tunnel segment after row changing, and the width of the installation position of a steel ring sheet before row changing of the pipeline; according to the obtained information of the pipeline needing to be rearranged and the width of the installation position of the steel ring piece, the length of the pipeline needing to be rearranged is obtained through calculation; the pipeline needing to be changed is fixed on the inner wall of the tunnel through the fixing points, the fixing points used for fixing the pipeline need to be cut in the process of changing the row of the pipeline, the number of the fixing points needing to be cut is calculated according to the calculated length of the pipeline needing to be changed, the calculated fixing points a
