Soil Static Lateral Pressure Coefficient Tester for Soil Lab Testing Axial loading 0-10kN
Equipment composition
This Soil Static Lateral Pressure coefficient of viscosity
instrument mainly consists of an air pump, control cabinet, air pressure reaction frame, displacement sensor, lateral pressure sensor, and computer software acquisition system. It displays and stores data graphs of pore pressure, deformation, rebound, pore pressure versus deformation, pore pressure versus time, deformation versus time, rebound graphs during loading and unloading, and the maximum, minimum, and average values of the data over time. Supporting Test Apparatus: K0 consolidation apparatus.
Computer Software Acquisition System: Real-time acquisition and monitoring of changes in displacement and lateral pressure.
Soil Static Lateral Pressure coefficient Instrument Features:
Constant, stepwise loading can be achieved through air and water pressure. Dedicated software can automatically collect and monitor displacement and pressure in real time. With various container devices, one instrument can perform multiple tests.
