SEU@CPTU-1 Multi-function Digital Pore Pressure Static Penetration System

The SEU@CPTU-1 multi-function digital hole pressure static penetration probe system has the advantages of novel mechanism, complete functions, high parameters, high precision, sensitivity and stability compared with the traditional in-situ static penetration test in China. It has a wide range of applications and complete theoretical system support. It is the most advanced multi-functional static penetration theory and technology products at home and abroad. It is worthy of popularization and application to improve the level of static penetration technology in China.

The SEU@CPTU-1 complete system consists of four parts: multi-function probe, data acquisition instrument, data analysis software and static penetration penetration device. It can measure cone tip pressure, side friction resistance, pore water pressure and shear wave velocity. Parameters such as soil resistivity; sensitive and accurate soil discrimination and division, and a series of parameters of in-situ consolidation coefficient, permeability coefficient, dynamic parameters, bearing characteristics, stress history and other undisturbed soils.
