Спосіб визначення геометричних параметрів колових підкранових колій

The main methods of controlling the geometry of circular runway of polar crane are reviewed. The existence of radiation in the Atomic Power Station premises offers insights into the process of geodesic works. People can access the reactor building only when the reactor is not working. Therefore the developed methods of geodesic measurements should provide the highest quality and reliability of obtained results, as well as partial or full measurements automation. The results of geodesic measurements are influenced by the air vibration, oscillation, and temperature drops between the floor and runway rails levels. Deformations of runway rails may lead to the outage of works. With the advent of new modern electronic tacheometers, the task was to develop a new method for measuring the crane track of the polar crane of the reactor compartment. The new method of defining the geometrical parameters of circular runways by the total station is suggested. The method involves defining the coordinates of points that are marked on the runway. The distances 20 mm from the runway edge with the 2.81 m interval are marked by the kern, after which 48 points with 3 mm diameter are drilled. Measurements are taken from three virtual stations with three fixed mount pillars with triggers, on which the electronic total stations or reflectors are installed. Mount pillars should be installed in such a way to protect them from knock down by the crane. For this purpose, they are installed on the distance of more than 0.7 mm from the protection sheathe, but close enough to take measurements. The geometrical parameters of the runway are analytically calculated according to the measurements results. By using the universal approximation algorithm for estimating the geometrical parameters of circular form constructions, the values of radius, diameters, and data for optimal alignment are found. Defining the geometrical parameters of circular runways by the recommended method increases the geodetic survey efficiency and decreases the time needed to receive a result. This, in turn, will save the resources and costs of the enterprise (Atomic Power Station).
