摘要
(US20170030527) The invention relates to engineering geodesy for monitoring a height and deformation of a pipeline.  The invention includes use of a complex of interrelated monitoring measures that include monitoring a control position of deformation control benchmarks using optic geodetic devices and mobile satellite geodetic receivers.  A state geodetic network is used only at an initial stage for reference of the network sites to the local system of coordinates.  Geodetic measurements are then converted to a local system of coordinates.  The invention decreases an amount of time and labor for detection of the oil pipeline coordinates for operational needs and simplifies a planned high-altitude position data exchange, storage and transfer during measurement.

(US20170030527) 1. A method for monitoring positions of an above-ground pipeline located in areas subject to permafrost conditions, comprising: installing deformation control benchmarks on piles of support foundations of the above-ground pipeline, the deformation control benchmarks being positioned at least 0.5 meters (0.5 m) above a ground surface;   installing deep benchmarks spaced apart by 1.5 kilometers (1.5 km) or less and spaced at least 50 m from any of the support foundations;   installing reference stations along the above-ground pipeline such that the reference stations are spaced from each other by between 20 km and 40 km from each other and are adapted to communicate with a server;   detecting initial coordinates of the deformation control benchmarks and the deep benchmarks during installation;   detecting initial heights of the above-ground pipeline at the locations of the benchmarks;   transmitting the detected initial coordinates and the detected initial heights to a server for building a digital pipeline model;   detecting subsequent coordinates and subsequent heights of the above-ground pipeline using a rover;   transmitting the detected subsequent coordinates and the detected subsequent heights of the above-ground pipeline to the server; and   determining any deflection of the above-ground pipeline by comparing the detected initial heights of the above-ground pipeline and the detected subsequent heights of the above-ground pipeline by the server. 2. The method of claim 1 wherein the detected initial coordinates correspond to coordinates in a state coordinate system based on state geodetic network benchmarks and wherein the method further comprises converting the coordinates in the state coordinate system to coordinates in a local coordinate system based on the deep benchmarks. 3. The method of claim 1, wherein determining any deflection of the above-ground pipeline further includes determining that a deflection has occurred when a difference between the detected initial heights and the detected subsequent heights are greater than a predetermined value. 4. The method of claim 1, wherein detecting subsequent coordinates and subsequent heights is performed at least once per month for a first year of pipeline service and at least twice per year thereafter. 5. The method of claim 1, wherein a device equipped with a GNSS receiver and a means of wireless connection is used as a mobile receiver for the transmitting steps. 6. The method of claim 1, wherein detecting subsequent coordinates and subsequent heights of the above-ground pipeline using a GPS/GLONASS transmitter is performed by an optic control device. 7. The method of claim 1, wherein the deformation control benchmarks are made of rolled steel that forms a sharp angle and are attached to a metal pilework or a support pile in such way that a top of the sharp angle is a top point of the deformation control benchmark and are detected during pipeline service. 8. The method of claim 1, wherein each pile of the above-ground pipeline includes a separate deformation control benchmark. 9. The method of claim 1, wherein the deep benchmarks include a metal pipe and has a head made of the stainless steel with a polished spherical surface, the metal pipe being installed into a bore of a concrete anchor and equipped with a protective case made of a metal pipe and filled with a sandy non-frost-susceptible soil. 10. The method of claim 1, wherein the deep benchmarks are installed to a depth that corresponds to a location where maximum seasonal soil thawing occurs rounded up to a nearest meter and is at least 11 meters. 11. The method of claim 1, wherein height sensors are installed on pipeline compensators at a location of maximum possible change of a position of the above-ground pipeline. 12. The method of claim 1, wherein each reference station includes a multi-frequency navigation units of GLONASS consumer or GLONASS/GPS of a phase mode, a multi-frequency GLONASS or GLONASS/GPS geodetic GNSS aerial device with multi-path and re-reflected signal suppression systems, an eccentricity value of a phase center that is no more than 2 mm, a device for fixing the reference station on a fixed object, a computer with a controller function to set up equipment of a permanent reference station, and software to perform main functions of the reference station. 13. A system for monitoring positions of an above-ground pipeline comprising: deformation control benchmarks installed on piles of support foundations of the above-ground pipeline;   deep benchmarks installed in such a way that their height remains relatively constant regardless of effects of permafrost conditions;   reference stations installed along the above-ground pipeline that include GNSS transmitters for creation of a local geodetic network; and   a server coupled to the reference stations and to a rover and configured to: receive initial coordinate and height data from the rover regarding a height and a location of the deformation control benchmarks,   receive subsequent coordinate and height data from the rover regarding a subsequent height and a subsequent location of the deformation control benchmarks, and   determine whether deflection of the above-ground pipeline has occurred by comparing the initial coordinate and height data to the subsequent coordinate and height data. 14. The system of claim 13, wherein the deformation control benchmarks are made of rolled steel that forms a sharp angle and are attached to a metal pilework or a support pile in such way that a top of the sharp angle is a top point of the deformation control benchmark and are detected during pipeline service. 15. The system of claim 13, wherein each pile of the above-ground pipeline includes a separate deformation control benchmark. 16. The system of claim 13, wherein the deep benchmarks include a metal pipe and has a head made of the stainless steel with a polished spherical surface, the metal pipe being installed into a bore of a concrete anchor and equipped with a protective case made of a metal pipe and filled with a sandy non-frost-susceptible soil. 17. The system of claim 13, wherein the deep benchmarks are installed to a depth that corresponds to a location where maximum seasonal soil thawing occurs rounded up to a nearest meter and is at least 11 meters. 18.
