Product Description

Newly Designed Digital Engineering Seismograph  For Refraction,Reflection And Masw Surface Wave

 

   The WZG-24C distributed high-precision engineering seismograph uses a 32-bit high-precision Σ-Δ ADC, supports 10,000-channel two-dimensional and three-dimensional seismic exploration, and can support 4,000 channels at a 1ms sampling interval. The instrument uses a 24-bit acquisition board and a USB interface for an external computer, which is flexible and lightweight; the exploration depth ranges from a few meters to several thousand meters; it is suitable for seismic work in reflection, refraction, surface wave exploration, pile foundation detection, ground pulse measurement, seismic imaging, vibration measurement and wave velocity (shear wave) testing; it is widely used in engineering geological exploration in the fields of water conservancy, electricity, roads, railways, bridges, urban construction, transportation, groundwater, etc., as well as resource exploration in the fields of oil, coal fields, coalbed methane, shale gas, metal mines and non-metallic minerals.

Scope of application

Investigation of foundation, roadbed cavities and karst exploration; classification of foundation soil types and investigation of diseased geological bodies; investigation of physical properties of foundation rock and soil media; inspection of foundation reinforcement effect and roadbed backfill rolling quality; investigation of bedrock depth and hidden geological structures.

2. Inspection of tunnel engineering

Investigation of tunnel routes and classification of cavern surrounding rocks; inspection of concrete lining quality; inspection of tunnel bottom and advanced detection monitoring; vibration monitoring.

3. Operation observation of large and medium-sized reservoirs

Detection of hidden dangers of embankments; measurement of reservoir siltation and inspection of silt discharge effect; inspection of construction of embankment dumping of large and medium-sized water conservancy hubs.

4. Inspection of bridge engineering

Investigation of bridge pier foundation types; inspection of concrete quality of abutment pile foundations; vibration monitoring of bridges.

5. Detection and evaluation of environmental and geological disasters

Investigation of landslides, karst, debris flows, goafs and active fractures.

6. Exploration of metal and non-metallic minerals

7. Two-dimensional and three-dimensional exploration of coal fields, coalbed methane, shale gas, oil and other resources
