Application of a Rapid Non-Core Drilling Exploration Ahead of the Tunnel Face using Water-Powered Hammer Drilling on...
Abstract: Generally speaking, in order to survey the geological conditions existing ahead of the face, tunnel excavation must be discontinued temporarily, and therefore it is necessary to bore over a long distance in as short a time as possible. To overcome these requirements, we have developed an exploration system with a water-powered hammer of down-the-hole drilling type, which is capable of surveying...

On-Site Visualization as a new monitoring scheme for tunnelling engineering
Abstract: This paper proposes a new monitoring scheme which is characterized by use of new type of instruments capabe of not only processing data, but also visually outputting them for immediate recognition of measured information by vision. Therefore, time required for all workers to notice occurrence of an event could be as small as the theoretical speed limit for data transmission, namely the speed of...
