Wave Speed Exploration Seismograph Seismic Wave Velocity Tester

Application:

a) Determination of the thickness of the overburden layer and the undulation shape of the bedrock interface.

b) Determine the position, width and distribution direction of hidden faults and cracked fracture zones.

c) Detect the development status of karst, gobs, burnt areas, collapsed columns, and underground caves.

l) Divide the sequence of loose sedimentary strata.

e) Investigation of landslides and subsidence and other geological disasters.

f) Geological mapping.

g) Quality inspection of foundation and determination of geotechnical elastic parameters.

h) Leakage detection of dams and reservoir dams.

For the excitation of seismic waves, the seismic source should be reasonably selected according to the requirements of the seismic task and the seismic geological conditions of the work area. The principle of determining the source system is that the effective seismic wave is strong and the interference wave is relatively weak; the frequency band is wide: when the source point is excited, the seismic record has good repeatability.

When using hammering vibration source, falling hammer vibration source, and mechanical impact vibration source, a special backing plate should be laid at the shock point to prevent secondary triggering caused by rebound.

To excite the SH wave, use the tap plate source, make the long axis of the plank perpendicular to the survey line, and the midpoint of the long axis be located on the survey line or the extension of the survey line, and make the plank closely coupled with the ground. In order to increase the excitation energy, appropriate weights can be stacked on the plank.
