A ground investigation system optimal for trackbed evaluation that supports the safe operation of railways.
In the railway industry, proper evaluation of the subgrade is essential to ensure the stability and safety of the tracks. Deterioration of the subgrade can lead to decreased train performance and increase the risk of derailment accidents. Detailed ground surveys are particularly required in areas with aging subgrades or where ground conditions are prone to change. The ground survey system "RI Cone" enables rapid and high-precision ground surveys in situ, providing crucial information for assessing the integrity of the subgrade. 【Application Scenarios】 - Ground surveys of subgrades in new track construction and renovation projects - Deterioration diagnosis of existing subgrades - Stability evaluation of embankments and cuttings - Assessment of liquefaction risk 【Benefits of Implementation】 - Quickly grasp the strength and soil quality of the subgrade, allowing for appropriate measures to be taken - Accurately evaluate the effectiveness of ground improvement, contributing to the efficiency of construction - Identify liquefaction risks in advance and strengthen safety measures - Enhance the safety of railway operations

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.
