Latest Patents

One of Toshiyuki Ueno's latest patents details a novel method for excavating and constructing tunnels. This inventive process is specifically designed for working beneath railways or roads, effectively navigating the challenges of construction on banking or level land. The method involves the excavation of pits on either side of the roadway, allowing an excavator to dig into one pit and emerge from the opposite wall through the ground in between. Central to this invention is a hollow casing unit that attaches to the rear of the excavator, which is equipped with a screw conveyor.

As the excavator progresses, additional casing units are sequentially connected, forming a continuous system that adapts to the excavation process. This innovative mechanism allows for the formation of the outer wall of the tunnel, as runs of casing units outline the required shape. Once the sand and soil have been removed, reinforcing steel bars and a mold are positioned inside the tunnel, with concrete poured into both the casing units and the space between the mold and wall. This approach ensures that these units become integral to the structure of the tunnel itself.

Career Highlights

Throughout his career, Toshiyuki Ueno has collaborated with esteemed organizations such as the Japanese National Railways and Kyokuto Boeki Kaisha, Ltd.
