The "Slit Injection Forepoling" is a tunnel excavation auxiliary method that allows for the insertion of a cuttable bolt at a low angle from beneath the support structure into areas of concern for rockfall, such as uncemented ground. By performing construction from within the cross-section, it reduces the skin fall that occurs from the top and achieves reliable injection through leak suppression. It is highly effective for ground improvement. 【Features】 ■ The slit processing of the bolt allows for the removal of the bolt's end. ■ It enables insertion from beneath the support structure, proving particularly effective in uncemented ground such as sandy hills, demonstrating higher effectiveness than conventional methods. ■ Since it involves pouring from beneath the support structure, it suppresses leaks caused by roughness in the boreholes through pouring from the position of the sprayed concrete, allowing for reliable injection. *For more details, please refer to the PDF document or feel free to contact us.

The "Fadom Method" uses "Denka ES," which hardens rapidly when mixed with cement milk, as a ground improvement material for various applications. By combining it with a dedicated injection machine and a mouth closure system, the construction performance and stability of the cement-based injection system for tunnel auxiliary construction have been improved. The dedicated injection machine automatically controls the pump flow rate, making it less likely to disrupt the liquid balance and resulting in minimal loss. It allows for stable discharge with consistent mixing using a trough mixer. It excels in ground improvement effects, construction performance, and stability. 【Features】 - "Denka ES" can be expected to enable permeation injection when combined with ultra-fine particle cement, allowing for localized improvement around bolts and steel pipes. - The Denka Setter (setting retarder) allows for arbitrary adjustment of gel time. - The control panel is compact with built-in management gauges, enabling injection of multiple systems by a single operator. *For more details, please refer to the PDF document or feel free to contact us.

The "Lattice Gutter" is a product that improves the construction accuracy and quality during the assembly of steel reinforcement for tunnel support structures, consisting of a main frame and a lattice of reinforcing bars that connect them. It allows for changes in the number of suitable pieces and the diameter of the main frame reinforcing bars according to the cross-sectional shape. Additionally, by combining it with our product, the sheet gripper "NETIS No. KT-190096-A," it enables the assembly of reinforcing bars without damaging the waterproof sheet. 【Features】 ■ Allows for piece division and changes in reinforcing bar diameter suited to the site ■ Improves construction accuracy of reinforcing bars ■ Can also be used as an alternative to internal support structures ■ Lighter weight compared to internal H-type support structures and improves the filling capability of the lining concrete *For more details, please refer to the PDF document or feel free to contact us.

"Injection-type Forepolling" is an auxiliary excavation method that combines injection materials and bolt materials to perform pre-support and consolidation improvement of the ground. Its primary purpose is to prevent the collapse of the tunnel face and to stop the expansion of looseness during tunnel excavation.

The "Offsite Material Management System" is a system that allows for centralized management of offsite production in the cloud. It enables smooth information transmission and timely sharing of material status among the site, offsite, and manufacturers, thereby reducing the complexities of material management tasks, which are a challenge in offsite production. With a balance of simple operability and visibility, it includes alert functions to notify of delivery delays. By utilizing this system, we aim to resolve the challenges faced in offsite production. 【Features】 ■ Balances simple operability and visibility ■ Timely sharing of material progress status ■ Alert function to notify of delivery delays *For more details, please download the PDF or feel free to contact us.
