Micronetwork for Shift Determinations of the New Type Point Stabilization

Abstract

The article describes stage geodetic measurements in the local spatial micronetwork in order to track shifts of a new type of point stabilization. The new point stabilization system is realized by ground screws. The design of stabilization should be applied in the creation of the setting out network for line construction. Verification of the stability was performed at 9-point local spatial micronetwork. Stability of network points was verified by 4-stage measurements in the period from November 2016 to November 2017. The average planimetric standard deviation of the points is 0.2 mm. The positioning allowable deviation is 1.6 mm. The height shift allowable deviation is 0.7 mm. No shift occurred at any point beyond the allowable deviation. The newly designed way of point stabilization is sufficiently stable and guarantees high precision in setting out networks.
