Ground investigation technology - Ground penetrating radar survey

Ground investigation technology - Ground penetrating radar survey

Underground buried pipes, underground cavities, concrete diagnosis - high mobility and rapid exploration are possible.

Ground-penetrating radar (GPR) is a non-destructive exploration method that utilizes electromagnetic waves. A radar antenna placed on the surface (100 MHz to 1.6 GHz) emits electromagnetic waves towards the ground, and receives the waves that are reflected back from various underground objects (material boundaries). The received reflected waves are processed and displayed as subsurface images. Compared to trial excavation surveys, it is cost-effective and allows for continuous exploration. It has high mobility and enables rapid surveying. It can explore regardless of the material of the target objects (pipes, cavities, rebar, structures, etc.). Exploration is possible up to a depth of about 3 meters (this may vary slightly depending on soil conditions). For more details, please download the catalog or contact us.

FCR Vibration Position Exploration - Exploration from Inside the Pipe

FCR Vibration Position Exploration - Exploration from Inside the Pipe

Subsurface Position Exploration: Predicting the Location of Unknown Pipe Openings from Inside the Pipe - Identifying Blockage Points [FCR Method Association]

If only the pipe entrance is known, it is possible to identify the route, estimate the location of the unknown pipe entrance, and proceed with excavation, dredging, and repairs of the unknown pipe entrance. Additionally, if there are blockages along the way, their locations can be identified, and support for quick excavation repairs will be provided. 【Exploration from inside the pipe】 If entry onto the railway is not possible, or if the exploration depth exceeds 5 meters, exploration from inside the pipe is optimal. Construction conditions: Each measurement unit must be insertable into the pipe.

Non-destructive testing "Electrical exploration"

Non-destructive testing "Electrical exploration"

Exploration methods with wide applicability! We will grasp extensive and high-precision ground characteristics.

At Kyoa Development, we conduct "electrical exploration," which measures the differences in the flow of electric current by passing current through the ground. This allows us to understand the presence of groundwater, stratigraphic composition, the shape of landslide surfaces, geological conditions, and underground cavities. Traditionally, vertical exploration, which measures the resistivity in the depth direction at specific points, was the main method used. However, in the field of civil engineering geology, two-dimensional resistivity exploration has become the mainstream method. 【Features】 〈Two-Dimensional Resistivity Exploration〉 ■ Capable of exploration in terrains with elevation differences ■ A method that does not involve vibrations or noise during fieldwork ■ Fewer operational constraints as it does not use hazardous materials such as explosives ■ Three-dimensional exploration is also conducted *For more details, please refer to the PDF materials or feel free to contact us.

Compared to resisting two-dimensional exploration

Compared to resisting two-dimensional exploration

Measurement is possible even in areas with vibration noise! Measurements and analysis can be done in a shorter time than before.

"Resistivity Survey" is an exploration method that estimates underground structures (mainly resistivity structures) by measuring the potential generated by electric currents flowing through the ground. It allows for detailed surveys to wide-area surveys depending on the electrode spacing (maximum depth of about 300m). Measurements and analyses can be conducted in a shorter time than conventional methods. It can be used for cavity and landslide surveys, as well as groundwater, hot spring surveys, and tunnel and river embankment investigations. 【Features】 ■ Possible to conduct detailed surveys to wide-area surveys depending on electrode spacing (maximum depth of about 300m) ■ Non-destructive survey considerate of the Earth ■ High-precision automatic measurements ■ Measurements and analyses can be conducted in a shorter time than conventional methods ■ Capable of measuring in areas with vibration noise *For more details, please refer to the PDF materials or feel free to contact us.

Reinforcement inspection, piping inspection, buried pipe inspection, etc. "StructureScan"

Reinforcement inspection, piping inspection, buried pipe inspection, etc. "StructureScan"

Non-destructive testing that does not create holes in floors or walls is possible! Resin pipes such as CD pipes are clearly displayed! We conduct exploration with the knowledge and technical skills unique to a manufacturer’s representative!

Our company provides services for rebar detection, piping detection, and buried pipe detection prior to core drilling, anchor installation, cutting, and chipping work. Since electromagnetic waves (weak) are harmless, there is no need for measures such as setting up controlled areas or prohibiting entry like with X-rays. Additionally, since there is no need to apply film to the wall, inspections can now be conducted in areas where film cannot be applied, such as on the floor. 【Features】 ■ X-ray (radiography) inspections can handle wall thicknesses up to 350mm, and 3D scans can handle up to 500mm. ■ Depth information of the inspection area can be obtained through slice images like in CT scans. ■ No need for measures such as setting up controlled areas or prohibiting entry like with X-rays. ■ Resin pipes such as CD pipes are clearly displayed. ■ 3D visualization inspection takes only 4 minutes. *For more details, please refer to the PDF document or feel free to contact us.

X-ray inspection

X-ray inspection

It is possible to check the condition inside concrete with film! It works on the same principle as medical X-ray imaging.

X-ray inspection is a method that involves irradiating concrete with X-rays from an X-ray generator, capturing the internal condition on a film attached to the back side of the concrete. Using the same principle as medical X-ray imaging, the developed film allows for the examination of the internal state of the concrete, which can then be used to mark the locations of embedded objects on the concrete surface. This enables construction work, such as core drilling and anchor installation, to be carried out without damaging or cutting through embedded electrical and plumbing pipes or rebar. *For more details, please refer to the related link page or feel free to contact us.*
