Product description :

ZD11 Hammering Shear Wave Speed Tester is A set of high-resolution, digital wave speed testing instruments with time-sampling, superposition, filtering, signal enhancement, noise suppression, real-time calculation on site, display of measured waveforms and test results. It is mainly composed of wave speed tester, three-component detector, trigger detector and special connection cable.

Application

Field investigation shear wave velocity test

Field investigation micro-tremor excellence cycle test

Shear wave and compression wave test for engineering survey;

Applicable standards

Code for Seismic Design of Buildings  GB 50011-2010

Code for Investigation of Geotechnical Engineering  GB 50021-2001

Code for Testing of Dynamic Characteristics of Foundation GB/T 50269-2015

Features:

10.4-inch high-definition and high-brightness color touch screen, with special touch pen;

The acquisition operating system is WinCE 6.0, and the analysis software supports winXP, win7, and win10 systems.

Data and graphics are saved in * .bmp, * .Excel, * .word formats, and word report formats can be issued;

Convenient operation, stable performance, industrial-grade motherboard, high signal-to-noise ratio, strong anti-interference ability, adapt to harsh environment;

Imported chassis, the whole machine is sealed, beautiful and firm, the structure is reasonable, and it has good anti-vibration, moisture-proof, waterproof, dust-proof performance;

The instrument uses a built-in rechargeable lithium battery, which can continuously complete work for no less than 16 hours, and is equipped with a dedicated charger

Working principle:

When the shock plate is struck on the ground and an impact force is applied to the ground, P waves and S waves propagate downward along the borehole formation. When the P waves and S waves propagate to the position of the detector, the detector can convert the P wave and The S-wave first arrival time and vibration waveform are converted into electrical signals and recorded by the instrument. The wave velocity value of the stratum between the two points can be calculated from the first arrival time difference of the adjacent P · S waves.
