NTTインフラネット List of Products and Services

Our company conducts "road surface condition surveys" using specialized small vehicles. We accurately detect fine cracks that cannot be captured by the human eye and scientifically diagnose the health of the road. This enables preventive maintenance management, leading to a reduction in lifecycle costs from a long-term perspective. Planned preventive maintenance can simultaneously achieve the longevity of road assets and the optimization of maintenance costs. 【Features】 ■ Inspection support technology performance catalog [Pavement Edition (crack rate, rut depth, IRI)] Publication No: PA010022-V0024 ■ NETIS registration number: TH-200003-A ■ 2024 Civil Engineering Research Center performance verification test (certified) ■ Using images obtained from stereo cameras, it is possible to measure road ancillary facilities, road width, and the height and dimensions of road signs. *For more details, please download the PDF or feel free to contact us.

• Geological Survey

"GAIA FITS" is a flood detection system that monitors the safety of residents 24 hours a day, 365 days a year. It continuously monitors the situation on-site in real-time and immediately notifies in case of abnormalities, automatically implementing traffic restrictions. It enables a reliable disaster prevention system even with limited personnel. 【Features】 ■ Disaster-resistant solar power: Ensures continuous operation even during power outages ■ Communication method via mobile phone networks: Flexibility in installation environments ■ Float-based detection: Operates appropriately based on water level detection ■ Nationwide support network: Continuous maintenance management system closely tied to the community *For more details, please download the PDF or feel free to contact us.

• Monitoring and Control Equipment

The "MMS" provided by NTT Infranet adopts a stereo camera system instead of the conventional laser method, enabling simultaneous acquisition of three-dimensional measurements and high-resolution images. By checking this image, it is possible to inspect equipment by discerning its color (rust) and patterns (cracks, text, etc.). Detailed understanding of the deterioration condition of equipment, which was difficult with the laser method, has become possible. 【Features】 ■ Winner of the 1st Infrastructure Maintenance Award (Minister of Internal Affairs and Communications Award) ■ Allows three-dimensional measurement, acquisition of equipment coordinates, and confirmation of aging deterioration of target equipment on the obtained images ■ High-resolution image acquisition enables measurement of thin objects like cables and suspension wires with millimeter-level measurement accuracy *For more details, please download the PDF or feel free to contact us.

• Information and communication equipment and infrastructure

"Triple IP" is a Geographic Information System (GIS) used for the maintenance and management of communication civil engineering facilities (such as manholes and utility poles) by the NTT Group. It is a system that accumulates and stores various data, allowing users to "overlay display," "search," and "extract" that data. Additionally, by adding various necessary layers, the system can be developed further. Users can check facility information and drawings while on the go (using a tablet) and send photos and videos of the site conditions (using a tablet or smartphone). [Features] - Centralized management and visualization of equipment and inspection data - Integration with a smartphone app for on-site inspections, enabling timely registration of inspection results - Possible integration with MMS travel information *For more details, please download the PDF or feel free to contact us.

• Information and communication equipment and infrastructure

We would like to introduce our "Sewer Smart Maintenance Tool." This technology consists of a system that centrally manages equipment and inspection information for sewer manholes and pipelines on a map, along with smart tools such as a 360° camera for sewer manhole inspections. It enables safe and efficient inspections of sewer manholes, allowing for the visualization and centralized management of inspection data. 【Features】 ■ With a 360° camera and dedicated app, it is possible to safely and efficiently capture and record the interior of sewer manholes and pipe openings without entering the manhole. ■ The diagnostic results of the equipment can be easily recorded on-site, and automatic creation of inspection reports is also possible. ■ Inspection results are centrally managed on a map for visualization. *For more details, please download the PDF or feel free to contact us.

Our company provides the "On-Site Reception Web System." This service digitizes the application process for underground facility surveys, construction consultations, and on-site requests, allowing for the consolidated reception of applications for telecommunications, electricity, gas, water supply, and sewage. Additionally, the system enables 24-hour reception, real-time sharing of application information, and centralized management of construction application information. 【Features】 ■ Consolidated reception for telecommunications, electricity, gas, water supply, and sewage ■ 24-hour reception via the system, real-time sharing of application information, and centralized management of construction application information ■ Automatic determination of the presence of underground facilities (optional) ■ Real estate inquiries/automatic responses to real estate inquiries (optional) *For more details, please download the PDF or feel free to contact us.

• Construction and process management software

This technology is a rust prevention method that applies a penetrating rust inhibitor to the surface of reinforced concrete to non-destructively protect the internal rebar from rust. While traditional methods have existed for applying coatings to the surface of reinforced concrete, they have been effective in suppressing the entry of external deterioration factors but have had little effect on already existing deterioration factors (such as chloride ions and areas of carbonation), resulting in insufficient rust prevention effectiveness. In this technology, a newly developed high-penetration rust inhibitor (Sabiran A) is applied to the surface of existing concrete and allowed to penetrate sufficiently into the interior (the surface tension of Sabiran A is 1/2.7 that of conventional products), non-destructively suppressing the latent deterioration of the rebar caused by internal deterioration factors. Furthermore, by applying a water-tightness enhancing agent (Sabiran P), the method simultaneously suppresses further entry of external deterioration factors, thereby providing long-term and stable rust prevention effectiveness for the rebar within the reinforced concrete. ■ Technical Explanation of the Improved Penetration of Sabiran A The rust prevention effect of Sabiran is achieved through the action of a rust inhibitor composition that contains the following composite surfactants: - Specific ether-type nonionic surfactants (maximum surface tension reduction capability) - Water-insoluble specific surfactants (significant wettability enhancement capability)

• Renovation and repair methods

The "KS Method" is a repair technique designed to stop water leakage from joints and cracks in concrete structures such as underground joint trenches, tunnels, box culverts, and manholes. It is a resin-based sheet-type waterproofing method that excels in long-term durability. 【Features】 ■ With a double structure of waterproof sheets and protective nets, it demonstrates resistance to groundwater pressure and can adapt to external water pressure of 0.1 MPa or less (equivalent to a water depth of 10 m). ■ It follows horizontal displacements (up to 20 mm) caused by earthquakes, preventing re-leakage from the repaired area. ■ It does not require special construction tools, minimizing the need for cable relocation even in tunnels with congested cables, thus demonstrating high workability. *For more details, please download the PDF or feel free to contact us.
