PURPOSE: A complex shell file, equipped with an optical fiber sensor which change intensity against the bending moment, and a construction method thereof are provided to measure semi-permanently through the optical fiber sensor. CONSTITUTION: A complex shell file, equipped with an optical fiber sensor comprises: a step of producing a plurality of composite shells(100-1,100-2,100-3) in advance in a factory; a step of forming a composite shell pile(200) by welding complex shells in the field; a step of linearly-excavating the ground with welding complex shells embedded by using equipment like an auger; a step of injecting an inner filler into an excavation hole; a step of embedding the composite shell pile to the excavation hole; and a step of reinforcing the head of the complex shell file by using a reinforcing cap. |
