EARTH SYSTEM SCIENCE Co., Ltd.
EARTH SYSTEM SCIENCE(ESS) is offering the comprehensive technologies in natural science with challenging spirits, aiming at the creation and conservation of the friendly and confortable natural environments in the world.
ESS provides MIRA and AURIS.
MIRA (Ultrasonic Tomography) is a now destructive method of inspecting the inner structure of concrete, reinforcement, caves, rock pocket, etc.
On the rear of the MIRA body, there are 48 allay type sensors (8×12matrix).
First is ultrasonic wave sat from CH1 is received at CH2-12.
Second, the ultrasonic wave is sent from CH2 and received at CH3-13.
Switching ultra-shear waves and receiving reflection waves at high speed.
MIRA receives 66 combinations (11+10+…+2+1) 1056route( 66×4×4) of signals and analyzes them, it can be used at 1.5m depth of structure because of using the ultra-shear wave that has strong penetrating power.
MIRA (Ultrasonic Tomography)
MIRA （Ultrasonic Tomograph）Technology
●Non Destructive Inspection for Inner Structure of Concrete
●Could Detection Reinforcement , Cave , Rock Pocket and Combined Duct
●Strong Penetrating Power , Could Inspect 1.5m Thickness of Concrete
AURIS（High Frequency Stress Wave Method）Technology
●Inspecting Sounding of Pile, Ground Anchor, Concrete Structure Non Destruction
●Light and Compact, Optimum to Inspection Crack or Sounding of Rock Slope, Dam Unit
●Inspection Depth of Rolling Stone or Pumice stone at Slope to Quantitative Evaluation
Example①：Inspection of Thickness of Reinforcement Concrete and
Reinforcement Rod and Polyvinyl Pipe
Example②：Inspection of Reinforcement Rod Arrangement and
Thickness of Tunnel Concrete
AURIS（High Frequency Stress Wave Method）
AURIS (High Frequency Stress Wave Method) isexploration to inspect extremity of structure or
crack of. Hit the target structure put the sensor (oscillation receiver element) to make a stress wave.
Measure the waveform and wave propagation time,select and receive specific frequency band
the most primacy reflect.
Using high directivity and high attenuation statistic at surface of structure, could detection reflection wave from extremity of structure and crack high probability.
