INSTALLATION FOR FIELD TESTING OF SOILS OF THE SUB-BALLAST FOUNDATION OF THE RAILWAY TRACK Russian patent published in 2022 - IPC E01B35/04 E02D1/08 G01N3/36 G01N3/40 

FIELD: railway tracks.

SUBSTANCE: invention relates to the field of the upper structure of the railway track, in particular to installations for field testing of soils under the ballast base of the railway track. The installation contains a stamp with a rod, a static support, a hydraulic jack with a hydrostatic pressure sensor and a system for measuring the settling of the die. The upper part of the rod is connected to the support through a jack. The measurement system is connected to the stamp through a rod. The device for setting the stamp into the ground is made in the form of a hollow cylindrical cutter with an open end. Cutting and loosening elements are made on the outer surface of the cutter. A stamp with a rod is installed inside the cutter with the possibility of movement by a drive. The die setting device is suspended on a rigid bracket and can be rotated around a vertical kingpin fixed on a static support. The rotation of the stamp around the axes is carried out by a hydraulic cylinder. The axes of rotation of the cutter and the axes of inclination of the device lie in the same plane and are perpendicular. The die settling measurement system is connected to the end face of the upper part of the double-sided jack rod.

EFFECT: complexity of testing is reduced.
