Measuring probe for monitoring residual deformations and temperatures of multilayer road structures

摘要

The utility model relates to the field of automated remote monitoring of the condition of roads during their operation, in particular, to obtaining objective data on the values of residual deformations and temperatures in the working layer of the subgrade and structural layers of pavement. The essence of the utility model is that the measuring probe for automated monitoring of residual deformations of multilayer road structures, including an external solid metal tube with placed outside magnetic assemblies, each consisting of two ring magnets with an interlayer disk, and an inner metal-plastic tube with measuring sensors. The cavity between the measuring sensors and the metal-plastic tube is filled with an organosilicon compound. Inside the metal-plastic tube contains a battery and a radio module, the upper probe tube, which is used as an antenna. Moreover, an additional Hall sensor has been added to the interlayer measuring boards inside the metal-plastic tube, while the Hall sensors are located at a distance of 10 mm from each other, which allows the determination of displacements according to the calibration schedule of the magnetic field strength only in linear sections, and the interlayer disks are made with several sizes, in the upper part of the plastic tube mounted mount for calibration device. The technical result is an increase in accuracy and an increase in the range of measurements of residual deformations due to the addition of an additional (3rd) Hall sensor to the measurement modules and calibration directly on the road. 8 ill.
