WZG-24/48C Seismic Refraction Equipment seismic refraction equipment engineering
The equipment supports a variety of excitation sources including hammers, sparks, and explosions. Its exploration depth can extend from just a few meters to several hundred meters, with the capability to achieve even deeper seismic data collection through time-lapse functionality. This apparatus is suited for a wide range of applications such as seismic reflection and refraction surveys, surface wave analysis, foundation pile testing, micro-seismic monitoring, seismic imaging, vibration measurement, and shear wave velocity testing. It plays an essential role in engineering geology exploration across sectors like hydrogeology, power generation, railways, bridges, urban construction, and transportation. Additionally, this seismograph is instrumental in resource exploration, aiding in the discovery of petroleum, coalfields, uranium deposits, and groundwater resources.
