Latest Patents

Masao Okabe holds a patent for a method and apparatus designed to determine angular and transversal displacements of a shield machine and a succeeding pipe. This invention is particularly useful in pipe-jacking tunneling. The patent outlines a system that includes a first light emitter on the shield machine, which projects a light beam along the central longitudinal axis. This beam is directed towards a pair of targets, each equipped with a scale, to form light spots. A second light emitter, located at the rear of the tunnel, projects another light beam to create further light spots. By reading these spots, the system can accurately measure displacements relative to a predetermined central axis of the tunnel.
