日本铁路技术研究所等单位已对超高压水在岩石钻掘中的应用技术进行过研究,但是,由于产生数千个大气压超高压水的设备过大及其所用的密封装置存在寿命问题,所以距现场的实际应用还有一段时间。后来,利用由美国“弗罗茵达斯特利”公司研制的超高压水发生设备才基本上实现了超高压水的实际应用,并使用了手持式钻孔机,气腿式钻孔机和安有悬臂导向装置的钻孔机为主 Japan Railway Technology Research Institute and other units have studied the application of ultra-high pressure water rock drilling technology, but due to the thousands of atmospheric ultra-high pressure water equipment is too large and the sealing device used life problems exist, so There is still some time away from the practical application of the site. Later, the use of ultra-high-pressure water generation equipment developed by the United States “Floindley” company basically realized the practical application of ultra-high pressure water, and the use of hand-held drilling machine, air leg drilling machine and safety Cantilever-oriented drilling machine based
