TBM Spraying System Subshot System
The material loss during mixing with the mixer is minimal, and it helps reduce rebound and dust.
The "Subshot System" continuously supplies special fiber-reinforced mortar "Denka PF Mortar" using a mixing pump and combines it with a liquid quick-setting agent "Denka Subshot L" to enable continuous spraying construction from the rear carriage of a TBM (Tunnel Boring Machine) and other equipment. This allows for rapid construction, reduction of underground work, and improvement of the working environment. Additionally, it minimizes material loss during mixing and kneading, reduces rebound, and decreases dust. 【Features】 ■ Continuous spraying construction from the rear carriage ■ Enables rapid construction, reduction of underground work, and improvement of the working environment ■ Minimal material loss during mixing and kneading ■ Reduces rebound and decreases dust *For more details, please refer to the related link page or feel free to contact us.
