PURPOSE: A protector with a measurement device is provided to measure a distance from the protector to a tunnel and to display the measured results through a monitor. CONSTITUTION: A protector(1) with a measurement device comprises a protector body(10), rails(20), and a measurement device. The protector body is installed inside a tunnel. The rails are installed on both surfaces of the protector body in a longitudinal direction. The measurement device comprises a power unit(31), a measurement bar(33), a controller(35), and a monitor(37). The power unit is moved along the rails. The measurement bar has a distance measurement sensor and is moved along the rail by the power unit. The controller collects signals measured from the distance measurement sensor and converts the signals into numerical data or three-dimensional image data. The monitor is installed on the inner surface of the protector body and displays the numerical data or three-dimensional image data.
