description To install a linear body at a desired position while effectively utilizing an internal space of a tunnel.SOLUTION: A tunnel excavator 100 comprises a skin plate 10 capable of supporting an inner wall of the natural ground, a cutter head 20 that is attached to the skin plate 10 and excavates the ground by rotation, a projection 81 which is provided on the skin plate 10 and which forms a groove 5 extending in the axial direction of the shield tunnel T on the inner wall of the ground as the skin plate 10 advances, and a delivery unit 90 for delivering the linear body 4 into the groove 5.SELECTED DRAWING: Figure 1 【課題】トンネルの内部空間を有効活用しつつ線状体を所望の位置に設置する。【解決手段】トンネル掘進機100は、地山の内壁を支持可能なスキンプレート10と、スキンプレート10に装着され、回転により地山を掘削するカッタヘッド20と、スキンプレート10に設けられ、スキンプレート10の前進に伴って地山の内壁にシールドトンネルTの軸方向に延びる溝5を形成する突起81と、溝5内に線状体4を送出する送出部90と、を備える。【選択図】図1
