Технологическая схема определения геометрических параметров подкрановых конструкций инженерных сооружений на подрабатываемых территориях

Abstract

During the operation of mining deposits located on the territories under development, engineering structures as whole or individual building structures are subjected to deformation processes in the vertical and horizontal planes due to displacements of the Earth's surface. To ensure their normal opera-tion, it is necessary to perform a certain set of geodetic and surveying works with a given cycle to determine the deformation state of both the territories being worked on and the engineering structures located on them, as well as the technological equipment used. At the same time, the efficiency and reliability of the measurement results obtained largely depends on the accepted technological scheme for performing a set of works. In addition, the volume of geodetic measurements performed must comply with the requirements of regulatory documents. Such building structures of engineering structures include crane structures, including columns, crane beams and tracks. To determine their geometric parameters, the relevant regulatory documents regulate the measurement procedure. However, this recommended technique, firstly, is technologically outdated, secondly, its use in a number of cases does not provide the required measurement accuracy and, thirdly, does not allow performing the entire volume of engineering and geodetic measurements in the territories being worked on. The article presents a technological scheme for determining the geometric (deformation) parameters of crane structures with the use of total stations, which provides the required measurement accuracy and, depending on the current situation in the territories under construction, can be realized by the proposed scheme.
