Utilizing ICT to streamline the measurement of dust concentration, which is essential for safety management, and the dissemination of measurement results.

• Tunnel construction

Equipped with various sensors prepared for the boom and linked to the cutting edge marking system, it achieves precise construction. It eliminates the intrusion into the cutting edge for root adjustment. 22nd National Land Technology Development Award - Excellence Award 10th Japan Robot Award - Minister of Land, Infrastructure, Transport and Tourism Award Ministry of Land, Infrastructure, Transport and Tourism New Technology Information Registration System NETIS Registration Number KT-230301-A

• Tunnel construction

A laser distance measuring device that integrates a laser distance meter and a display laser light is installed in multiple units around the operator's seat of the spraying machine, allowing for continuous measurement of the thickness during spraying using the laser distance meter. By displaying the excess or deficiency of the spraying thickness on the spraying surface with color (green/red) and irradiation patterns (steady/blinking) using the display laser light, the operator can work while grasping the spraying thickness in real-time. The data of the continuously measured spraying thickness from the laser distance measuring device is automatically saved in the control box and can be output to a report. This eliminates the need for measurement hole operations near the cut face that were previously conducted after spraying work, thereby improving work efficiency and safety.

• Tunnel construction

- Accurate control of drilling position and angle, as well as adjustments to the spacing and amount of explosives based on ground conditions, will improve quality and workability. - Early detection of weak areas allows for the calculation of locations at risk of surface collapse, enhancing safety.

The "B-type" is a laser projector system for tunnel construction. The marking method of this system (mechanical excavation) allows the operator to always confirm the cross-sectional shape by continuously projecting an afterimage of the tunnel face perimeter. It also enables excavation with reduced concrete encroachment. Additionally, in rock bolt projection, it is possible to display not only the position but also the direction as an afterimage. 【Features】 - Marking that does not disappear even during mechanical excavation - Eliminates the need to spray as it enters directly below the tunnel face - Requires simultaneous use with a laser marking system *For more details, please refer to the PDF materials or feel free to contact us.
