METHOD FOR MONITORING THE POSITION OF SUPPLIES OF THE GROUND PIPELINES UNDER PERMANENT FROZEN CONDITIONS

摘要

1. A method of monitoring the position of pipelines of elevated laying in permafrost conditions, characterized in that it includes the installation of deformation grades on the foundation pile piles of the pipeline support at a distance of not less than 0.5 m from the earth's surface, the installation of underground deep benchmarks that are placed at a distance of not more than 1 , 5 km from each other and not more than 50 m from the supports, the installation of reference stations along the pipeline at a distance of 20-40 km from each other, which are configured to receive and transmit information to the server; of deep depth benchmarks and reference stations determine their coordinates in the state network, the obtained coordinates are transferred using the key to local coordinates, which are transmitted to the server, after which, in the local coordinate system, they carry out a zero cycle of measuring coordinates of deformation marks relative to ground depth benchmarks, determine the coordinates of the marks the zero vertical and vertical position of the pipeline, the coordinates of the marks are also transmitted to the server, and based on the results of all measurements, a design digital model of the pipeline is built then, during the operation of the pipeline, they carry out control measurements of the coordinates of the deformation marks characterizing the current planned height position of the pipeline, while the control measurements are made using mobile GPS / GLONASS receivers, which ensure the receipt and transmission of measurement data to the server, build the current digital model of the pipeline, which is compared with the design digital model of the pipeline, and sections of the pipeline are determined on which the deviation of its current position from the design project
