Preceding Sky Edge Subsidence Plan_KT-180071-VE
Understanding the preceding subsidence ahead of the cutting edge, enhancing collapse prevention and the advancement of A measurement.
**Overview** When excavating unstable ground such as loose soil or poor-quality rock (like fractured zones), there is a risk of the face becoming unstable and collapsing. This is believed to be caused by insufficient strength of the ground, posing dangers not only to workers but also potentially causing significant impacts to third parties, such as surface subsidence. The advanced ground subsidence gauge installs measuring instruments within long steel pipe supports to measure subsidence in front of the face at 50 cm intervals, continuously monitoring shear strain and pre-displacement of the ground, which are precursors to collapse. It detects face collapse through real-time, high-precision measurements and is equipped with an alarm system. **Features** The SAA is very slim and has flexible joints, making it easy to insert into long steel pipe supports for displacement measurement. By using a dedicated measurement guide pipe installed within the steel pipe during insertion, it allows for repeated use, thereby reducing measurement costs. Measurement does not require a multi-channel data logger; it can be conducted directly via a dedicated interface to a PC, resulting in a simple system configuration that easily accommodates multiple connections. *For more details, please refer to the PDF document or feel free to contact us.*
