12/24/48 channels High Resolution seismograph, Geological Survey Equipment, Geological prospecting instruments.
Description
- WINXP operation system, 24 digits
- Hammering, electric spark or explosion as excitation seismic resource
- Test range from meters to thousand meters, time extension function for even deeper information
- Test modes: reflection, refraction, surface wave, pile integrity test, micro-tremor test, high density seismic imaging, vibration test, shear wave test
- Widely used in engineering geology exploration and mineral resource exploration
Application fields
- Surface wave exploration: covering layer layered survey; differentiation band survey; underground cavity and geology flaw investigation; roadbed and other structure body flaw detection;
- Reflection and refraction survey: basement layered, buried depth, water engineering advanced geology base investigation;
- Multi-wave high density imaging: foundation, roadbed cavity detection, karst exploration;
- Micro-tremor test: tall building and bridge vibration test, foundation investigation, earthquake safety assessment;
- Pile integrity detection: pier and pile detection;
- Blast vibration test: city vibration and explosion assessment;
- Shear wave test: rock elastic mechanical parameters test.
