Tunnel excavation apparatus to which spectroscopic analysis method is applied

A tunnel excavation apparatus to which a spectroscopic analysis method is applied, comprising:

• a main body;
• a first driving unit that is connected to the main body and moves the main body forward;
• an excavation unit that is rotatably installed in front of the main body and contacts the ground to excavate the ground;
• a second driving unit that is installed on the main body so as to be connected to the excavation unit and rotates the excavation unit;
• a ground component measurement unit that measures a component of the ground excavated by the excavation unit using a laser induced breakdown spectrometer;
• and
• a control unit that controls an operation of the tunnel excavation apparatus to which a spectroscopic analysis method is applied according to the component of a ground, and wherein the ground component measurement unit sucks spoil powder of the ground excavated by the excavation unit, accommodates the spoil powder inside, and then discharges the spoil powder outside, and
• irradiates a laser to the spoil powder of the ground accommodated inside with the laser induced breakdown spectrometer to measure the component of the ground, and wherein the ground component measurement unit includes a first suction mechanism that sucks the spoil powder of the ground excavated by the excavation unit, an accommodating mechanism that has a chamber formed to accommodate the spoil powder of the ground sucked by the first suction mechanism and has a transparent window formed on one side through which a laser is transmitted, the laser induced breakdown spectrometer that irradiates the laser to the spoil powder of the ground accommodated in the chamber through the transparent window to measure the component of the ground, and a second suction mechanism that sucks the spoil powder of the ground accommodated in the chamber and discharges the spoil powder from the accommodating mechanism.
