Tunnel investigation using images: "Mobile Tunnel Imaging System"

Tunnel investigation using images: "Mobile Tunnel Imaging System"

Capture structures while driving! Accurately detect changes such as cracks and water leaks!

The "Mobile Tunnel Imaging System" is designed to serve as foundational information for the accurate maintenance and management of structures. By using multiple digital video cameras and lighting to capture images while in motion, it can accurately detect changes such as cracks and water leaks by visualizing the condition of concrete surfaces. 【Features】 ■ Significant reduction in inspection work time Shooting speed: 10 km/h to 80 km/h ■ Improved safety of inspection work and work environment (Can shoot at high speeds without lane restrictions) ■ Highly reliable development diagrams (can also be effectively utilized when conducting visual inspections separately) ■ Understanding the condition of ancillary structures *For more details, please download the PDF or feel free to contact us.

Geological survey of small cross-section tunnels

Geological survey of small cross-section tunnels

Quantitative surveys of ground loosening and cavities around small cross-section tunnels have become possible.

**Necessity and Background** - In waterway tunnels that have been constructed for some time, cavities may form behind the lining due to water leakage. These cavities can cause loosening in the consolidated ground, change the earth pressure acting on the lining, and potentially lead to the destruction of the lining. - Therefore, it is necessary to quantitatively investigate the cavities behind the lining in tunnels that have been in existence for a long time. **Product Overview** - Investigations can be conducted from inside small cross-section tunnels. - The penetration rate, thrust, and rod rotation speed of rotary percussion drills and rotary boring machines within the tunnel are measured and recorded, allowing for a quantitative investigation of previously unknown small cavities and the loosening condition of the ground. *Please refer to the leaflet for more information.* **Features** - Collection of detailed N-value data of the ground - N-values can be obtained every 1 cm (compared to 1 m in general geological surveys). - Quick investigation - No need for temporary facilities and no use of core tubes, allowing for a rapid survey. - All-direction investigation - Drilling can be conducted in all directions from inside the tunnel. - Investigation in small-diameter tunnels - Investigations can be conducted in tunnels with a diameter of 2 meters or more. - Investigations from the ground surface are also possible. - Target geology - All types of geology. *For more details, please refer to the technical documentation or contact us.*
