Achieving rapid and high-precision ground surveys in their original position!
In the infrastructure industry, as the aging of structures progresses, it is important to accurately understand the condition of the ground and to carry out appropriate maintenance and management. In particular, changes in ground strength and deterioration of soil quality directly affect the safety of structures, necessitating prompt and detailed investigations. Traditional survey methods not only take time and incur costs but can also make it difficult to obtain accurate data. The ground survey system "RI Cone" enables rapid in-situ ground surveys, supporting the safe operation of infrastructure structures. 【Usage Scenarios】 - Foundation ground surveys for infrastructure structures such as bridges, tunnels, and roads - Diagnosis of ground deterioration in existing structures - Measurement of the effectiveness of ground improvement works 【Benefits of Implementation】 - Cost reduction and shortened construction periods through rapid surveys - Accurate diagnosis through high-precision data acquisition - Early detection and countermeasures for liquefaction risks

basic information
【Features】 - It is possible to quickly and in detail obtain and calculate physical property values such as ground strength, soil classification, density, and water content ratio in situ. - It allows for the assessment of consolidation conditions in soft ground such as dredged fill sites, verification of ground improvement effects, and liquefaction determination. - It can be applied to ground with an N value of about 20 when combined with a dedicated penetration vehicle. 【Our Strengths】 Since our establishment in 1974, we have developed numerous technologies that utilize RI (radioisotope) measurement techniques in the construction field. As an "RI measurement device manufacturer," we handle everything from development to manufacturing, rental, and maintenance in-house. As a "construction consultant," we conduct field surveys utilizing RI technology, in addition to standard ground investigations and soil tests. We are the only company well-known in the industry for demonstrating comprehensive strength through these two pillars, contributing to the assurance of quality on construction sites.

Company information
Since our establishment, we have developed many measurement technologies that utilize various types of radiation emitted by radioisotopes, particularly gamma rays and neutron rays, in the construction field, specifically the RI method. The characteristics of the RI method are "non-destructive," "rapid," and "high precision." Currently, based on the development of unique measuring instruments that leverage these characteristics and the proposal of investigation methods, we focus on consulting that comprehensively addresses issues related to ground and soil construction by combining soil and geological surveys. Additionally, we also engage in the sale and rental of these RI instruments. Please feel free to contact us if you have any requests.
