Hideaki Nakagawa, Hiroyuki Oishi and Eisaku Muraoka

 

West Japan Engineering Consultants, Inc developed a Portable Borehole Camera system, which are lightweight, operation made easy and a low cost device. Although various borehole camera systems have a long history and various equipment has been developed, it is highly advanced function and high cost made it difficult to use in geologically unstable borehole where the wall may collapse due to jamming consequence. Numerous functions such as defining the locations and opening of the width of cracks, water investigation, check of destroyed condition of the incrinometer, underground geological observation, check of grouting condition, check of cavern and open crack, check of trumpeters zone and check on the geological condition of borehole deformation test are all made easy to perform even in poor and unstable geological condition.
