According to the method, the vertical projection point is set by using the laser plumb aligner, and the prism is directly replaced at the position of the laser plumb aligner, so that the trouble of hanging the steel wire is avoided, the influence of external environment on the stability of the steel wire is not required to be considered, the workload of frequently adjusting the prism is reduced, the prism is fully automatically observed by using the total station, the reflection patch is not required to be stuck on the steel wire, the manual aiming measurement is performed, the influence of measurement errors caused by human factors is avoided, the efficiency is improved, the time is saved, the measurement work can be separately performed on the ground and underground, and the investment of personnel and equipment is saved.

However, the operation of the scheme also has some problems, because the prism needs to be replaced at the hole site, and meanwhile, the complete alignment needs to be ensured in the hole site operation process, the operations can seriously affect the precision of the whole casting point, the small deviation in the hole site instrument installation process can cause the inaccuracy of the whole measurement result, and the stability of the whole hole site can also seriously affect the result.
