**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.*

In roads and railway tunnels currently in use, there have been cases where the invert is damaged due to the uplift of the ground over a long period, such as from expansive soil, which hinders vehicle passage. To prevent such situations, an invert displacement gauge can be used to measure the amount of uplift in the subgrade during construction, allowing for countermeasures to be implemented as necessary and confirming the convergence of displacement after the measures are taken. 【Benefits of Implementation】 - By using it regularly, you can check for the presence of potential slab bulging behavior, and if such behavior is confirmed, numerical analysis can be conducted using the measurement data to select countermeasures such as invert struts. - The subsequent uplift can be approximated using an exponential function to predict the residual displacement that the structure will experience after countermeasures are implemented. - The analysis reproduces the residual displacement to verify the stress on the countermeasures. - Combined with A measurements in the arch section, it allows for the confirmation of the long-term stability of the entire tunnel cross-section. *For more details, please refer to the PDF document or feel free to contact us.*
