Products Discribtion

WZG Series Earth Seimic Reflection & Refraction Seismograph Equipment

In order to respond to ground noises and shaking such as caused by quakes, volcanic eruptions, and explosions, we need professional geophysical instrument-seismometer. It can record the motion of ground during an earthquake, which is very small vibration. Depends on the the different usages, 12/24/24/48/96 or more seismic cables may be needed for reflection/refraction survey. Based on transient multi-point Rayleigh wave exploration, shallow reflection/refraction measurement, wave speed shear wave measurement, pile foundation meaurement and many other surveys WZG can do, it is widely applied in building base, doadben and foudation engineering detetion, tunnel construction detection, large and medium reservior monitoring, bridge engineering inspection and many other aspects.

Features & Function

Features:

* Quick sampling: true 24 A/D, fatest sampling interval-50μs
* Perfect reproduction of the original signal: superior amplitude and phase coherence, ultra-low distortion performance, advanced high-cut filter with  better than 72dB out-of-band suppression
* High-speed data transmission: instantly complete the transmission of large quantities of seismic data; in the process of background noise                  monitoring, it can accept the trigger signal at any time and enter the formal sampling process.
* Powerful software: advanced graphic technology; screen can display 128 channels wave train; convenient amplitude equalisation display mode; at a glance static time markers and so on.
* Flexible configuration and easy expansion: users can choose DOS or WINDOWS processing software according to their own situation, and can also upgrade the instrument to a 48-channel seismometer by purchasing a data acquisition plug-in board and software.
* Support for coverage measurements: by using our company's PZF series of electronic cover switch, it will be very convenient to achieve a variety of field coverage measurements, greatly improving the efficiency of field shallow reflection seismic exploration operations.
* Great durability: outstanding resistance to vibration, moisture and dust.

Functions:

* Inspection of foundations, road foundations and foundation works:
1. Foundation and roadbed cavity surveys and lava exploration
2. Stratification of the quaternary cover
3. Classification of foundation soil types and investigation of diseased geological bodies
4. Investigation of the physical properties of the foundation geotechnical media
5. Effectiveness of foundation reinforcement and 1uality inspection of backfill compaction of road base
6. Investigation of bedrock burial and hidden geological formations
* Tunnel engineering inspection:
1.Tunnel route survey and classification of cavern surrounding rock
2. Concrete lining quality checks
3. Undertunnelling and pre-tunneling
4. Vibration monitoring
* Operational observation of large and medium-sized reservoirs:
1. Detection of dyke hazards
2. Measurement of siltation in reservoirs and checking the effectiveness of silt removal
3. Construction inspection of large and medium-sized water hub berm throwdowns
* Bridge Engineering Inspection:
1. Investigation of abutment foundation types
2. Inspection of concrete quality of bridge abutment pile foundation
3. Bridge vibration monitoring
* Environmental and geological hazards detection andevaluation:
1. Investigation of landslides, karst, mudslides, air-mined areas, active fractures
