Multichannel Seismograph Analysis Surface Waves Geophone Seismic Cable Seismic Survey Tools Site Shear Wave Refraction Reflection Seismic Study Seismograph
Main Applications and Features
The instrument uses hammering, electric spark or explosion as the excitation source to explore depths from a few meters to hundreds of meters, and also can use the time-delay function to obtain seismic data from deeper strata. It is very suitable for seismic work in reflection, refraction, surface wave exploration, pile detection, ground pulsation measurement, seismic reflection, vibration measurement and wave velocity (shear wave) test, etc. It is widely used in engineering geological exploration in water conservancy, electric power, railroad, bridge, urban construction, transportation, etc. It can also be used in resource exploration in petroleum, coal field, uranium mine and groundwater.
