Elastic wave pile bottom karst cave detector, a specialized instrument for the construction industry

TS-RD1203 (A) Elastic Wave Pile Bottom Cave Detector is based on the principle of elastic wave reflection. The probe is equipped with a high-power elastic wave excitation device and a multi-channel elastic wave detector. During testing, the probe is placed at the bottom of the hole, and the system automatically excites the elastic wave. When the elastic wave propagates to the rock layer at the bottom of the hole and encounters structures such as caves, cracks, and weak strata, it is reflected back. The elastic wave detector receives the reflected signal and can determine the depth position of the abnormal structure based on the changes in the strength and propagation time of the received reflected signal.

n Product Introduction

TS-RD1203（A）The elastic wave hole bottom cave detector is based on the principle of elastic wave reflection. The probe is equipped with a high-power elastic wave excitation device and multiple elastic wave detectors. During testing, the probe is placed at the bottom of the hole, and the system automatically excites the elastic wave. When the elastic wave propagates to the rock layer at the bottom of the hole and encounters structures such as caves, cracks, and weak strata, it reflects back. The elastic wave detector receives the reflection signal and can determine the depth position of the abnormal structure based on the changes in the strength and propagation time of the received reflection signal. By adjusting the probe at different positions at the bottom of the hole, multi-point detection can be carried out in different directions at the bottom of the hole, achieving full coverage of hole bottom detection and ensuring sufficient coverage、Effectively detect the horizontal distribution and depth of karst caves at the bottom of the hole.
