Description

This utility model relates to the field of engineering geodesy and can be used to control the position of underground and surface pipelines.

From the existing level of technology there is a known method for determining the horizontal and vertical position of an underground trunk pipeline (RU 2527902, publ. 09/10/2014). This method describes a device for determining the horizontal and vertical position, which is a vertical rack, rigidly fixed to the pipeline and moving with it. A corner is welded to the rack, on which a deformation mark is applied. The devices are located on the main pipeline at a distance of no more than 1 km from each other. The stand is welded to the clamp, which is bolted to the pipe. A communication unit with an in-line inspection device is installed on the device. The disadvantages of this technical solution are the presence of an in-line inspection device, communication units with an in-line device, as well as the binding of benchmarks using GPS / GLONASS satellite systems, which complicates the monitoring process.

Closest to the claimed technical solution is a method of monitoring the position of pipelines of elevated laying in permafrost conditions (RU 2582428, publ. 04/27/2016), which describes the deep benchmark. At a distance of not more than 50 m from the pipeline, deep soil benchmarks are installed, which consist of a metal pipe, a reference head made of stainless steel with a polished spherical surface, and concrete “anchors” installed in the well, while the benchmarks are equipped with protective casings from a metal pipe, filled with sandy non-porous soil. During the operation of the pipeline using mobile GPS / GLONASS receivers, control measurements of the coordinates of the deformation marks characterizing the current planned and vertical position of the pipeline are carried out, the measurement data is transmitted to the server and the current digital pipeline model is built. The disadvantages of this technical solution are the complex installation process of the benchmark, as well as the lack of attachment to the pipeline, which does not allow to accurately determine the position of the pipeline.

The task to which the claimed utility model is directed is to create a device easy to manufacture, install and use, with the help of this device an increase in the accuracy of determining the results obtained on the displacement of pipelines is achieved.

This problem is solved due to the fact that the claimed device for determining the plan-height position of the pipeline consists of a metal pipe and a square metal plate mounted on it, which is perpendicular to the scanning beam, when the plate is attached to the pipe, there are stiffeners, the plate also has an opening for leveling rails, and below the plate on the pipe is installed a geodetic benchmark.

The technical result provided by the given set of features is to determine the displacement of pipelines in difficult mining and geological conditions with high reliability of the results.

The claimed utility model is used for geotechnical monitoring using airborne laser scanning.

The essence of the utility model is illustrated by drawings, where in FIG. 1 - shows a General view of the device for determining the plan-height position of the pipeline; in FIG. 2 - shows a diagram of the installation of the device on the pipeline.

The device for determining the plan-height position of the pipeline is a metal pipe 1 with a square metal plate 2 placed on it, which is perpendicular to the scanning beam. When fixing the plate to the pipe, there are stiffeners 3. The plate also has a hole (slot) 4 for leveling rails. A geodetic reference point 5 is mounted under the plate on the pipe. The device is attached with a clamp connection 6 to the underground pipeline 7

The slot 4 in the plate 2 is necessary for the use of leveling rails. The leveling rod is used for the control determination of the height position of the device for determining the plan-height position of the pipeline. Leveling rail - a standardized geodetic device, which consists of two bars of the I-section, interconnected by metal fittings, which allows folding the rail for transportation. The rail has graduation on both sides.

The geodetic benchmark (mark, sign) is used to link the device for determining the planned height position of the pipeline into the geodetic network created for monitoring, control instrumental measurements, as well as to determine the altitude possible displacement during instrumental measurements (leveling) and the planned determination of possible displacement (theodolite course ) when it is impossible to use an air laser scanner due to weather and other conditions. The geodetic benchmark consists of a ball, a embedded plate welded to a device for determining the plan-height position of a pipeline and a metal corner or a metal tube (body).

The plate of the device for determining the height-and-height position of the pipeline is painted in light colors, mainly white, since white gives the greatest reflection of the laser during scanning, and is also well identified on a high-precision aerial photograph, which is necessary during monitoring. Laser scanning combined with aerial photography captures changes in the inclination or lowering / uplift of the plate when the position of the pipeline underground changes.

Preferred dimensions for the metal plate are 40 × 40 cm, 40 × 50 cm or more.

The use of this device for determining the plan-height position of the pipeline makes it possible to obtain displacements of the underground pipeline under the influence of exogenous and endogenous geological processes on the pipeline. The recommended number of laser reflection points for more accurate scanning is nine pieces per square meter, the quality of photography with new types of cameras achieves a pixel of up to 6 mm in size from a height of 200 m. The density of the point cloud when scanning at low altitudes of the aircraft will be high and will allow to obtain large the number of reflections from the surface and from the plate; when the position of the pipeline in space changes, the position of the plate will change. When you re-scan and combine multiple scans, you will see a change in the position of the plate.
