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.
Adopting a our self-developed position measuring system and the mechanism of excavation and soil discharge used in the mud presssure techique, this method can implement long-distance curve piping with high accuracy to a wide range of soil conditions from rock to soft ground.
Reverse Ace system provides a NO-DIC solution that replaces the damaged and aging piples with new pipes without excavation.
Non-destructive exploration is the exploration technology that does not damage the structures.
This device is used to explore the rebar of concrete structures. It is possible to explore maximum depth up to 0.40m.
This device, with functions that have not been available before, is ultrasound inspection equipment that can measure accurately the concrete internal features.
This device checks safely the continuous transport of the complex cut shape of cardboard.
This device has a camera attached to the transmiting and receiving antena, confirming the status in the pipes as well as and use electromagnetic wave checking the cavity arround the pipes.
This is the image processing software technology that substitutes for concrete building visual inspection This software will automatically detect the cracks from images captured by a digital camera.
A non-destructive testing technique which uses the elastic impact wave method to determine if the grout in the sheathing tube of a PC internal bridge has been sufficiently filled.
It is now possible to detect differences in level with a single digital image instead of measuring tapes and verniers. No installation required. You can begin using it right away by simply inserting the USB flash drive containing the software.
An unmanned helicopter equipped with a high-spec camera. Since it is controlled remotely, it can access high-up places or places inaccessible to humans.
By using an electric drive system, we were able to achieve both increased speed and less effort compared to the manual gear.
Hand hole reinforced by aramid fiber sheet.Reconstruction enables the aging of a hand hole.Construction is possible in narrow situations with many cables.
By directly transmiting strong pulling force (20t), left-cable removal method forcibly remove abandoned cables the pipes that were not removed, which will make effective use of pipes facilities that could not be used before.
A-FRP method is the method to repair the pulling pipe by repair the corroded part which is up to 50 cm from the ground by using aramid FRP products to the reinforcing material of joints of pulling pipes which especially corrode serverly.
Corresponds to a long span of 250m.Real-time measurement of the propulsion thrust during safety construction.
It is the emergency battery to use in harsh environments such as high humidity.
A way to see in night time construction or work in the dark.Easy to carry with one hand.Can be used continuously for 8 hours.
It is a lightweight, compact, high-performance filtering device for drainage to the public sewer, such as the accumulated water in a manhole.
Protect roads from sudden increases in water like torrential rains.
