Dilatometer, dilatometer system and control method for performing a dilatometer test

摘要

Dilatometer comprising a blade having a first blade surface and a second blade surface converging at a blade tip. The dilatometer includes a rigid piston movably disposed in a first recess in the blade, pushing means for applying pressure in the first recess to cause the piston to protrude from the first blade surface through a piston opening, and a displacement sensor disposed in the first recess. first recess and configured to measure a displacement of the protruding piston. The dilatometer includes a pore water inlet unit located on the piston and configured for the inlet of pore water, a water space connected to the pore water inlet unit via a discharge guide, and a pore water pressure sensor located in the water space and configured to measure a pore water pressure.
