We utiize NO-DIG technology, which was developed based on NTT's R & D results, to continue to take part in improving social infrastructure efficiency, as well as to contributing to global environmental protection.
The device can identify underground facility
The device, under simple operation, can identify underground facility with high accuracy and will help preventing equipment accidents.
■SafetyBy using the direct method (low frequency), the device can measure without opening or closing the lid of manhole, etc, making it unneccessary for water fetching, pit entrance, ventilation, reducing the transport limit, which lead to reducing work accidents and improving work efficiency.
■AdaptationBy using the direct method (low frequency), the device can measure without opening or closing the lid of manhole, etc, making it unneccessary for water fetching, pit entrance, ventilation, reducing the transport limit, which lead to reducing work accidents and improving work efficiency.
■EfficiencyPossible rapid attendance (in case using long distance type transmitter)
■High performanceCan turn the transmitter ON / OFF using the mobile phone (in case using long distance type transmitter)
| Direct method |
Is the location detection method in which the transmitter (handy type, long distance type) is connected to the optical fiber cable tension plate (steel wire), etc. and send direct signal |
|---|---|
| Clamp technique |
Is the location detection method in which the device is hold to the optical fiber cable or metal cable by clamp, sending the signal through induction |
| Sonde technique |
Is the location detection method in which the Sonde-type transmitter, which can send signal itself is mounted to the end of the wire rod, joining the internal non-metallic conduit (empty pipe) |
Underground buried objects exploration (make company's equipment safety/for new company's contruction）
