This paper reports the development and testing of an innovative type of earthmoving machine. The track-type belt conveyor (TTBC) can remove soil horizontally from deep excavations. The TTBC is more flexible than traditional conveyors used in factories, because it is self-moving (via two tracks) and foldable. Moreover, several TTBCs can work together to transport a continuous stream of soil over long horizontal distances, which can significantly improve earthmoving efficiency. Field tests were performed to assess the practical feasibility of single and multiple TTBCs. They were used in a long, narrow, deep excavation below a railway station. The site was constructed using a top-down method with a single soil exit at one end. The tests showed that the new TTBC is flexible and efficient for removing non-cohesive soils from deep excavation sites.
