Abstract: Provided are a sensor fixing device embedded in a concrete structure and a method thereof. The present invention can fix a sensor for monitoring a concrete structure not to be exposed to the outside of the concrete structure by embedding a sensor fixing device in the concrete structure beforehand when the concrete structure is formed, and can embed the sensor fixing device for fixing the sensor in the preformed concrete structure by crushing the concrete structure. Since the sensor is embedded in the concrete structure and is strongly in contact with the inner surface of concrete by elastic springs having high stiffness, the present invention can accurately acquire the moving data of the concrete structure. Also, the present invention does not need an advanced work for attachment when the protruding sensor is attached, and can remove a main cause that spoils the appearance due to the protruding sensor.
