Turning invisible risks into visible peace of mind. GrandShear sees underground installations without excavation, preventing accidents before they happen.
The Grand Sia is a probe designed around the axes of [explosive power], [mobility], and [exploration capability]. [Explosive Power] ● No assembly or setup preparation is required. ● Can be used immediately without any time loss. [Mobility] ● Easy to handle with a well-balanced weight distribution front and back. ● The control PC can be detached from the main unit and used separately even during measurements (connected via wireless LAN). [Exploration Capability] ● Clear images using a chirp method. ● Easy-to-view images due to diverse processing functions.

basic information
We will confirm whether the route of the buried pipes is correct and check for any unknown pipes that are not shown in the drawings. ■ Exploration before excavation work on roads and sites ■ Exploration before excavation work on station platforms ■ Exploration to prevent damage accidents caused by excavation work [Ground radar detects buried objects, cavities, and water underground through reflected waves] Ground radar emits electromagnetic waves into the ground. If there are metal pipes, plastic pipes, cavities, or water in the soil, it can be identified by the reflected waves that bounce back. Furthermore, by processing the data of the measured reflected waves, clearer images of the underground conditions can be obtained. 【Exploration Process】 1. Collection of preliminary information Obtain drawings from the owners of the pipes buried on-site, such as electric, gas, and water pipes. 2. Collection of on-site information Assume the condition of buried pipes based on local manholes, drainage ditches, gutters, and streetlights. 3. Construction design Predict the route of the buried pipes based on the collected information and design the construction. 4. Exploration using ground radar 5. Test excavation and excavation work

Applications/Examples of results
"During road construction, we accidentally drilled into gas and water pipes!" "During plumbing work, we accidentally cut electrical wires!" To prevent such accidents, prior excavation has mainly been conducted until now. However, there are cases where buried pipes can be accidentally damaged during preliminary checks. By using ground-penetrating radar, it is possible to confirm the location of buried pipes more easily without digging holes in the ground. In urban areas, existing buried pipes can overlap in complex ways, making it difficult to accurately grasp the underground situation using only documents like burial plans. In such locations, it is particularly reassuring to use ground-penetrating radar to check for buried pipes. [Applications] Before excavation work on roads or properties. Before excavation work on station platforms. To prevent damage accidents caused by excavation work.

Company information
Many of the social infrastructures, such as roads, tunnels, bridge piers, railways, water supply and sewage systems, and ports, which were intensively developed after the period of high economic growth, will reach over 50 years since their construction around 2030, raising concerns about the aging of social infrastructure. Additionally, due to the declining birthrate and aging population, Japan is facing a decrease in its population, leading to challenges such as labor shortages and worsening fiscal conditions. As a result, there is a growing need for the establishment of maintenance cycles for future social infrastructure, with increasing demands for "inspection," "diagnosis," "repair," and "renewal." Measurement technology services, based on the "knowledge," "experience," and "technology" cultivated since its establishment in 1995, provide services including the sale, repair, and calibration of non-destructive testing equipment and buried object detection devices, as well as customization and development of equipment and software, rental services, consultation, instructor dispatch, and seminar hosting, aiming to contribute to the development of social infrastructure and a society where people can live with peace of mind.
