High-speed forepolling "SP-IF method"
It's an economical high-speed forepolling method that advances by "digging 3 meters at a time" with ease.
The "SP-IF method" is an economical high-speed fore-poling that allows for easy work with "advancement of 3 meters at a time." A 2.5m hollow FRP bolt is connected to the rear end of a 4m self-drilling bolt, allowing for a total fore-poling length of 6.5m. It achieves a minimum of two layers of top-end bolt reinforcement at all excavation locations. 【Overview】 ○ Implemented for every three steel supports (advancing 3m at a time) ○ Narrow excavation while cutting away the subsequent FRP pipe ○ Striking the drive coupler to avoid damage to the FRP bolt ○ SP-IF excavation length: 3.0m For more details, please contact us or download the catalog.
