Background
Along with the rapid promotion of urban construction in China, urban rail transit construction projects represented by subways are rapidly promoted. At present, in the construction of subway projects, a shield method becomes a preferred construction method due to the advantages of high mechanization degree, small influence on surrounding environment and the like.
In the process of tunnel shield construction, in order to ensure the accuracy of the advancing direction of the shield machine, besides the need of perfect geological survey and reasonable engineering design and tunneling parameters, the real-time monitoring is also needed, namely, a total station is arranged in the tunnel, the advancing direction of the shield machine is guided through the total station, and meanwhile, the forming gesture of the spliced duct piece is also needed to be measured, so that the gesture of the shield machine is adjusted in time.

Therefore, after checking the coordinates of the bracket, the bracket can be moved forward to a station to transfer the coordinates to a new bracket. The traditional retest method comprises the following steps: and removing the total station on the existing bracket, and retesting the coordinates of the existing bracket by erecting the total station in the tunnel. The retest method has to stop the work of the guide system and stop tunneling so as to detach the total station on the bracket; the retest work has a certain influence on shield tunneling, consumes relatively much time, needs to frequently perform layout and actual measurement of control points in the tunnel, greatly increases the workload of measuring staff, and influences the progress of a construction site.
