PROJECT FOR CREATING A NEW IMPROVED SYSTEM OF HYDRODYNAMIC LEVELING

They were studied and analyzed by the National Polytechnic University of Armenia and created by HDLS – 10D and by the National University of Architecture and Construction of Armenia of Geodesy of Problematic Laboratory, improved with Practical and laboratory test works performed three samples of DHLS respectively. Based on the methods of their measurement and calculation of vertical movements, the authors proposed a project of a new improved system of the HDLS in which the following changes were made to the previous systems: a mobile tank was installed in the working fluid tank, which is half immersed in the working fluid. The movements of the mobile tank are regulated at a constant speed by a micromotor installed above the working tank. Three electrode needles were installed in the reference sensor, the lowermost of which is for the comparative damping of the movement of the faster-moving line of curvature of the initial part of the piezometric movement line of the liquid, the second as a reference for the measurement of the reference sensor to take, and the third to stop the movement of the working fluid after the end of the first cycle of measurements, which equalizes the surface of the working fluid in all sensors, after which the reverse measurement process is performed from the still surface of the liquid with uniform movement by the motor. Due to the same speed of movement of the working fluid, the measurement process from the still surface of the liquid, and the same cross-section of the sensor connections and polyethylene pipes, the resistance to fluid movement decreases, as a result of which the degree of measurement accuracy of the system increases.
