TS48-1 towed 3D high-resolution seismic detection system
Product introduction
TS towed array 3D high resolution seismic detection system uses the reflection wave, surface wave and inverse scattering wave generated by seismic wave in the uneven geological body to detect the characteristics of underground space geological body. The main detection targets are the collapse of urban roads within 25 m of the shallow layer, large underground water pipelines, karst caves, bomb shelters, dikes, etc.
The TS towed array 3D high resolution seismic detection system has four models: TS48-1 (48 channels), TS36-1(36 channels), TS24-1 (24 channels) and TS12-1(12 channels).
System features
TS towed array 3D high resolution seismic detection system is designed to solve the problems of small detection targets and many interference sources in the city. A high frequency acceleration sensor is designed, which has a bandwidth of 0.1 Hz to 6000 Hz and a sensitivity of 2.5V /g. The wideband characteristics can ensure the acquisition of rich wideband information, and the single shot data have reflected wave, surface wave, back- scattering wave and direct wave signals at the same time. The high sensitivity property can ensure the acquisition of weak signals and improve the detection depth. To improve the construction efficiency, the towed gravity detector is designed, which can be quickly assembled and disassembled on site. Combined with the configured aerodynamic source and electromagnetic shock source, the effective bandwidth of the measured data can reach 1500 Hz, and the limit resolution can reach 0.5 m.
The main control tablet computer can be separated, large screen high brightness LCD display, battery built-in.
48 acceleration sensors can be mounted, according to the detection target and detection accuracy requirements, can be arranged into a single row of 48 channels, double rows of 24 channels, three rows of 16 channels, four rows of 12 channels and six rows of 8 channels geometry. TS48-1 array is a 3D detection system, especially suitable for the investigation of urban road collapse and dike structure hidden dangers, multiple measurement lines can realize three-dimensional imaging.
