We can provide suggestions on inspection works and evaluation methods for the damage of various types of structures. This also includes a detailed examination for evaluating the cause of damage and planning for repair or strengthening work.
“Infrastructure patrol” with patrol inspection vehicles equipped with video inspection systems to find damage on the road surface.
High altitude inspection work
Check the altitude directly by visual inspection using heavy machinery etc.
We use a pole camera at places where direct visual inspection is difficult to confirm damage.
The interior of a high altitude structure is also subjected to impulsive sound inspection with a dedicated device.
Inspection and evaluation by digital image processing
The state of the structure is accurately recorded, inspected and analyzed based on the captured digital image
Inspection of filling condition of grout
The filling condition of grout in the transverse prestress tent of the prestressed concrete bridge is evaluated by the impact elastic wave generated by the hammer.
Check with infrared camera
By capturing the difference in temperature of the structure with the infrared camera, we check the U ribs where water accumulated and repair it.
Magnetic particle testing test
Magnetic particle flaw detection uses the "leakage magnetic flux" phenomenon generated from the scratched part. By magnetizing the specimen, the magnetic powder (or fluorescent magnetic powder) of the ferromagnetic material scattered on the surface is adsorbed to the scratched part. By observing this we will detect fine cracks.
Impact Acoustic Method
If you cannot visually inspect the inside of the structure etc. directly, we will conduct an inspection using the reverberation sound when hit with a hammer or the like.
Left:Generating the acoustic wave by hammer Right:recording acoustic wave
Semi-Automatic Ultrasonic Inspection (SAUT) for Steel Plate Deck
When a fatigue crack of a right angle type steel plate is detected, the inspection result is recorded by a slide operation of semi-automatic ultrasonic inspection (SAUT).
Remote monitoring technology of fatigue crack
Fatigue crack propagation of steel structure can be remotely monitored over a long period by remote technology.
