Data Recorder Seismic Instruments 24 Channels Acquisition Seismograph
High Resolution Seismic Data Recorder 24 Channels Acquisition Seismograph
Application
Foundation, subgrade and foundation engineering detection: foundation, subgrade cavity investigation and karst exploration, stratification of Quaternary overburden layer, classification of foundation soil types and investigation of diseased geological bodies, investigation of physical properties of foundation rock and soil media, foundation reinforcement effect and subgrade backfill Rolling quality inspection, bedrock buried depth and concealed geological structure survey.
Tunnel engineering detection: tunnel route survey and cavern surrounding rock classification, concrete lining quality inspection, tunnel bottom inspection and advanced detection, vibration monitoring.
Detection and evaluation of environmental and geological hazards: investigation of landslides, karsts, debris flows, gobs, and active faults.
The functions of the equipment include: transient multi-point Rayleigh wave exploration, shallow reflection measurement, shallow refraction measurement, wave velocity (shear wave) measurement, multi-wave high-density seismic image, pile foundation inspection, civil engineering quality inspection, site constant Time fretting measurement, vibration blasting measurement, etc.
