Subsurface Position Exploration: Predicting the Location of Unknown Pipe Openings from the Track - Identifying Blocked Areas [FCR Method Association]
If only the pipe outlet is known, it is possible to identify the route, estimate the location of the unknown pipe outlet, and proceed with excavation, dredging, and repairs of the unknown pipe outlet. Additionally, if there are any blockages along the way, their locations can be identified, and support for quick excavation repairs can be provided. 【Exploration from the Track】 If access to the track is possible and the exploration depth is within 5 meters, exploration from the track is feasible. Construction conditions: It is necessary that a dedicated survey device or a Super Yellow, etc., can insert the transmitter "sonde" into the pipe.
Subsurface Position Exploration: Predicting the Location of Unknown Pipe Openings from Inside the Pipe - Identifying Blockage Locations [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.

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.

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.

To prevent damage accidents! Before construction, check the rebar condition and cover thickness of the concrete structure.
"Reinforcement Detection of Concrete Structures" allows for the confirmation of the reinforcement condition and cover thickness of existing concrete structures before any modifications are made, in order to prevent accidents such as rebar cutting or damage to embedded objects. There are two types of detection methods: electromagnetic wave radar method and electromagnetic induction method, which are selected based on the cover thickness and the target objects. [Features] ■ It is possible to confirm the reinforcement condition and cover thickness of concrete structures before construction. ■ There are two types of detection methods: electromagnetic wave radar method and electromagnetic induction method. *For more details, please refer to the PDF document or feel free to contact us.
