METHOD OF DETERMINATION OF DEFORMATION CHARACTERISTICS OF PROTECTIVE TIGHT SHELL Russian patent published in 2015 - IPC G01M99/00 

FIELD: measurement equipment.

SUBSTANCE: method of determination of deformation characteristics of a protective tight shell consists in marking by pre-set sections of the protective tight shell of control points and execution of cycle-by-cycle identifications of their position. Control points are bound to geodetic field compilation points, the measurement information is analysed. The field compilation geodetic substantiation is formed as many-tier both outside of the structure, and inside it in the uniform coordinates system. This coordinates system is combined with the coordinates system of the protective tight shell, the studied points are places in moment, transitional, momentless zones of structural elements of the protective tight shell on its external and internal surfaces, monitoring of geometrical parameters is performed step by step.. During the monitoring the internal and external geometrical parameters of the protective tight shell are simultaneously determined at all stages of observations. Positions of the studied points placed in a momentless zone are determined with an accuracy providing reliable determination of the total expected maximum value of deformation of reinforcement bars.

EFFECT: improvement of accuracy of deformation measurements.
