Title: Innovations in Tunnel Boring Machines: The Contributions of Junpei Kawade

Introduction

Junpei Kawade, an inventive mind based in Ichikawa, Japan, has made significant contributions to the field of tunnel boring through his innovative patents. With a total of two patents to his name, Kawade's work focuses primarily on enhancing the attitude control systems of tunnel boring machine shields, which are crucial for efficient tunneling operations.

Latest Patents

Kawade's latest patents showcase his commitment to improving tunneling techniques. The first patent, titled "Attitude Control Means of Tunnel Boring Machine Shield," presents an improved attitude control system that utilizes a laser beam transmitter situated in an already bored tunnel. This system allows for the detection of any deviations from the set tunneling direction. When such a deviation is identified during operations, specifically while the forward end cutter head is rotating and the shield is propelled towards the tunnel face, strategic adjustments are made by selectively driving multiple jacks installed at the rear of the shield. This real-time correction of deviation significantly enhances the efficacy and accuracy of tunnel boring operations.

The second patent, "Method and System for Performing Attitude Control of Tunnel Excavating," outlines a comprehensive approach to attitude control for tunneling machine shields. The system involves a similar mechanism, where a variety of jacks at the tail end of the shield are selectively activated based on detected deviations from the intended path. An indicating and controlling unit first displays the deviation, prompting the operation of circuits linked to the jacks. This precision ensures that only those jacks necessary for correcting the deviation are utilized, thereby optimizing the tunneling process.
