Construction of the maintenance cycle

It is necessary to build a certain maintenance cycle, and to manage it to continue using public infrastructure in the long term and safely.
Inspection → Diagnosis → Measures → We will be active as the first runner to connect a record well.
 

Inspection of the structure

Our "inspection of the structure" which is pride most
These duties are apt to seem most simply, but it is basics in basics. The structure is successive and is environmental and sooner or later, by factors such as the external force, deteriorates.
With the inspection, I never overlook observing such situation surely, future danger.

[various inspection methods]

[the results of the Structure inspection]
2017
・The Kanto district maintenance station jurisdiction Bridge inspection duties

(Kanagawa, Chiba, Saitama, Gunma)

Investigation, diagnosis of the structure

I am asked well. "What is the difference between inspection and investigation? "

Our recognition
Perform observation (confirmation) of present status with the inspection superficially now.
The complexion is seen by all means, and a heartbeat sound and the affected part which ached are palpated when I have an examination in a doctor.


It thinks with "inspection".


Then what is an investigation diagnosis?
One or ... Which will deteriorate how in future what you worsened for where is the worst at the bad point that I observed in inspection

Similarly, when I compare it to a doctor
I check the disease that I cannot confirm with eyes by using drawing blood and X-rays, an electrocardiogram, the MRI.
It is exactly like that and investigates the cause of the investigation into structure by various instruments and knowledge to study every day and is right thinking with suggesting the best measures.


[investigation into steel structure item]
・Magnetic Particle Testing
・Ultrasonic Testing
・Penetrant Testing
・Ultrasonic thickness measurement

[investigation into concrete structure item]
・Test hammer examination
・Neutralization examination
・Compressive strength examination
・Corrosion degree examination of the internal reinforcing rod
 

Measurement, examination of the structure

Loading test

It is "When I check a Japanese dictionary What is" power

・The action that lets the standstill of the object or an exercising state cause a change, and causes transformation to an object. This is described.

Structures are always doing small movement.

It…
If a person becomes cold, a body shrinks, but the structure shrinks by a change of the temperature (temperature) equally, too.
There is the feeling that height sometimes shrinks with the very heavy thing, but the structure turns to support it and is twisted.
In addition, when is tense, the person shrinks, and shake, but is different from the strain of the person in the strain of the sazugani structure, but wind and an earthquake…It always shakes with the traffic of the car (vibration) and is.

We right measure these small movement and causative "power" using every instrument as seen in eyes.

"The power "is available for control to some extent.
However, there is not it when the control in the process with the structure deteriorating with age does not judge the current situation to include a structure now precisely.
I come to be able to connect to the preventive maintenance by measuring the present current situation by a small unit.

・Vibration Measurement

・Stress frequency measurement

3D measurement technology

I will raise the inspection which is our main force, an investigation diagnosis, the added value of a measurement, the examination by adopting a 3D technology.

Also, I reduce shortening in a working hour, reduction of the human error by the difference of the skill of the member of inspection more and, the reduction of the risk for the accident by the work at the high place, work with the traffic regulation, the work between the night, carry it out by utilizing a 3D technology of non-contact type three dimensions measuring instrument and fotogurametori.

However, the 3D technology needs a high technique in spite of being the hardware passing softly. We make an effort every day so that these techniques are used to the main force in the future and will allow you to meet the needs of the customer surely.
