This invention discloses a four-track, three-line method for muck removal and transportation in variable cross-section tunnel anchors. For tunnel anchors with steep axial inclination angles, four shared tracks are used to form three lines: one is a large-gauge integrated equipment and material transport line, and two are small-gauge circulating muck removal lines. First, the integrated equipment and material transport line, driven by a power mechanism, pulls a transport platform to transport the relevant equipment and materials for excavation at the tunnel face.
