SET SEISMIC CROSS HOLE

Product catalog summary

Overview
The document describes the Seismic Cross-Hole Set by Solgeo, designed for borehole surveys to measure compression (P) and shear (Sv) seismic waves in various materials such as ground, soil, rock, concrete, and embankment dams.

Specifications

P Waves: Generated using the SOLGEO SPARKER, which operates at power levels from 100J to 300J and frequencies from 100 Hz to 6 kHz. It requires water-filled boreholes.
S Waves: Generated using the SOLGEO GEOSv, which produces both upwards and downwards signals to invert shear wave polarization without P wave noise. The Solgeo AVG is the paired receiver.
ATLAS Seismic Energizer: Provides pulses to Geos and Sparker probes with a simple user interface and integrated control of vertical shear wave polarity.

Applications

Seismic cross-hole (2 or 3 boreholes)
Seismic down-hole
Seismic tomography
Ground elastic modules estimation
Cavities/faults detection
Detection of infiltration

Components

Pressure regulator for pneumatic coupling of S-wave transmitter and receiver
Atlas energizer for P- and S-wave transmitters
GEOSv transmitter for vertically polarized shear waves
Sparker transmitter for compression waves
Interchangeable high-voltage connection cable
Inclinometer probe (Inclis30) for 3D borehole deviation measurement
Hydrophonic receiving probe for compression waves
Geophonic receiving probe for shear waves
Connection cable for receiver probes and inclinometer probe
2-channel high-sampling ALLinONE data logger

SET SEISMIC CROSS HOLE Two specific borehole sources are used to generate seismic signals and one (or more) receivers are used to detect the first arrival of the seismic wave; the distance between boreholes at each depths is measured using a borehole deviation survey (Inclis30). Wave velocity is calculated as the ratio between the distance at each depth and the measured time. SOLGEO SPARKER is an automatic source to generate P waves; different levels of power (from 100J to 300J), frequency contents from 100 Hz up to 6kHz; it must be used in boreholes filled with water. SOLGEO GEOSv is used to...
