Shortened construction time and reduced costs with Drill Jumbo construction. No need for specialized drilling machines or personnel.
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.

Company information
When developing a new product, it is necessary to hold individual meetings in each area such as machinery, hydraulics, electricity, and programming, and coordinating these can be quite challenging. Additionally, when it comes to helping those in each field understand the usage and construction conditions, a significant amount of time is required for explanations. Our company is capable of addressing each of these areas. Furthermore, we can leverage our extensive experience in on-site construction to provide technology and proposals, enabling us to offer quicker responses and development products that meet your needs.
