ジオマシンエンジニアリング List of Products and Services

The technology allows for the installation of φ139.8mm large-diameter steel pipes over long distances using a drill jumbo, which is a general-purpose excavation machine for mountain tunnels, without the need for specialized machinery. Traditionally, it was considered difficult to install such large-diameter steel pipes into the ground using a drill jumbo, but various innovations and the development of specialized tools have made this possible. 【Features】 ■ Improved workability ■ Enhanced settlement suppression effect ■ High construction precision ■ Reduction in process and costs ■ The bending rigidity of the steel pipe is about three times that of AGF (in the case of double-pipe specifications) *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The perforation exploration device can be installed on conventional general-purpose machines such as drill jumbos and boring machines to digitize the perforation conditions. Data analysis is also straightforward, allowing for a comprehensive evaluation of geological characteristics and estimation of rock strength. 【Features】 ■ Compatible with almost all hydraulic rock drills used domestically ■ Can be installed on machines other than drill jumbos ■ Capable of single-shot exploration *For more details, please contact us or download the PDF to view.
