Deviation correction method for open-ground long-distance curve pipe jacking project

The invention discloses a deviation rectifying method for a ground-open long-distance curve pipe jacking project, and relates to a pipe jacking deviation rectifying process, which comprises the process steps of drawing a culvert pipe track contour line, selecting a monitoring point, excavating a monitoring well, setting an equidistant point, excavating a vertical shaft, excavating a monitoring hole, installing a range finder, and monitoring the excavation precision of a pipe jacking by using the range finder. The method comprises the following steps: drawing a culvert pipe track contour line on an open ground above a long-distance curve jacking pipe, selecting a proper point to excavate a monitoring well at a central line of the culvert pipe track, excavating vertical shafts at equidistant points on two sides of the culvert pipe track, and excavating a monitoring hole penetrating through the monitoring well between the two vertical shafts. The pipe-jacking excavation precision is monitored through the range f
