Non-destructive testing "Maintenance Management"

We will investigate the soundness of the overlay concrete, the condition of the foundation ground, and the presence of voids.

At Kyoa Development, we conduct maintenance management operations such as tunnel and bridge inspections. Since the conditions (backfill, foundation ground, concrete thickness, structure, etc.) vary for each target structure, experience and advanced know-how are required. Our company proposes maintenance management methods that achieve maximum effectiveness at minimal cost by utilizing our achievements in soil investigations and various exploration and testing techniques. 【Business Content】 ■ Tunnel Maintenance Management ・Visual and sound inspections ・Radar ■ Bridge Inspections ・Touch, visual, and sound inspections *For more details, please refer to the PDF document or feel free to contact us.

Non-destructive testing "Electrical exploration"

A versatile exploration method! It allows for a comprehensive and high-precision understanding of ground characteristics.

At Kyoa Development, we conduct "electrical exploration," which involves passing an electric current through the ground to measure differences in the flow of the current. This allows us to understand the presence of groundwater, stratification, the shape of landslide surfaces, geological conditions, underground cavities, and more. 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 approach. 【Features】〈Two-Dimensional Resistivity Exploration〉 ■ Capable of exploration in terrains with elevation differences ■ A method that does not involve vibration or noise during fieldwork ■ Fewer operational constraints as it does not use hazardous materials like explosives ■ Three-dimensional exploration is also conducted *For more details, please refer to the PDF materials or feel free to contact us.

Non-destructive testing "Auris Survey"

Suitable for buried object root depth surveys, boulder surveys, structural integrity assessments, and more!

At Kyoa Development, we conduct the "Auris Survey," which utilizes the reflection phenomenon of elastic waves to non-destructively investigate the length and integrity of structures. By using elastic waves in the high-frequency range of 10 kHz to 100 kHz, we can detect the locations of cracks and other issues within the structure. Additionally, we are registered with NETIS and have obtained patents for "Dynamic Diagnosis Methods for Piles or Structures" and "Shape Diagnosis Methods for Natural Structures." 【Features】 ■ Easily measure length ■ Capable of surveying bridge piers, PC piles, PHC piles, H steel piles, steel sheet piles, wooden piles, stone columns, bedrock, and more ■ Can measure the length of piles under footings and steel sheet piles under caulking (superstructure) ■ Able to investigate the presence of buckling, cracks, etc. *For more details, please refer to the PDF materials or feel free to contact us.

Non-destructive testing "Magnetic Survey"

It can be used for exploration in the depth direction, exploration just below the surface, and exploration below the seabed.

At Kyoa Development, we conduct "magnetic surveys" such as vertical magnetic surveys (land) and horizontal magnetic surveys (land and offshore). By measuring magnetic anomalies from the surface to underground, we can estimate the presence, depth, and planar distribution of buried objects without damaging the surface. While it is often used for bomb detection, it can also be utilized for the detection of iron objects such as iron pipes and sheet piles. 【Business Activities】 ■ Vertical magnetic surveys (land) ■ Horizontal magnetic surveys (land) ■ Horizontal magnetic surveys (offshore) *For more details, please refer to the PDF materials or feel free to contact us.

Non-destructive testing "Elastic wave exploration"

Seismometers are densely arranged along the survey line, enabling extensive and high-precision understanding of ground conditions!

At Kōa Development, we conduct "elastic wave exploration," which generates vibrations near the surface (using explosives or similar methods) and investigates geological structures and engineering information such as soil hardness through the differences in the speed at which elastic waves (P-waves) travel through the ground. We also evaluate stratification, rock classification, and geological area classification based on the results of the elastic wave exploration. Currently, high-density elastic wave exploration, which allows for detailed placement of receiving points and analysis of velocity inversion layers, has become mainstream. 【Features】〈High-Density Elastic Wave Exploration〉 ■ Can grasp a wide range of ground structures in a short time ■ Can detect velocity inversion layers that could not be analyzed with conventional elastic wave exploration ■ Ground experts analyze and evaluate the exploration results ■ Provides engineering information about the ground estimated from elastic wave speeds *For more details, please refer to the PDF document or feel free to contact us.

Non-destructive testing "Ultrasonic Testing"

Surveys can be conducted in narrow sea areas and shallow waters! We also introduce multi-channel shallow reflection methods that allow for deep investigations!

At Kōa Development, we conduct "acoustic wave exploration," which allows for detailed investigations and deep surveys by changing the sound source and frequency. By emitting sound waves towards the seabed and observing reflections at acoustic impedance boundaries, we can understand the geological structure beneath the sea surface. We carry out everything from measurement to analysis in-house, providing rapid and highly accurate exploration results. 【Features】 ■ Detailed investigations and deep surveys are possible by changing the sound source and frequency. ■ A wide range of surveys offered: - Investigation of burial conditions in ports and shipping routes using parametric acoustic wave exploration. - Surveys of active fault lines in coastal areas and other shallow marine investigations. - Geological structure surveys at depths of several hundred meters using boomer and sparker technologies. *For more details, please refer to the PDF materials or feel free to contact us.

Non-destructive testing "Diving exploration"

It is possible to accurately identify the detailed locations of hazardous materials on the seabed! Divers dive into the sea to directly investigate the seabed.

At Kyoa Development, we conduct "submarine exploration," which allows for detailed investigations that are difficult to understand from surveys conducted at sea (on ships). Divers go underwater to carry out visual inspections and use handheld simple magnetic survey devices for the investigation. It is possible to accurately identify the specific locations of hazardous materials on the seabed. 【Business Contents】 ■ Preliminary survey (understanding the target area) ■ Setting the exploration area ■ Conducting submarine exploration ■ Creating submarine exploration result diagrams ■ Preparing and submitting exploration reports *For more details, please refer to the PDF materials or feel free to contact us.
