Saber EX Lock Bolt
The expansion-type rock bolt made of reinforcing steel pipes, developed by K.F.C. Co., Ltd., contributes to the longevity of tunnels.
This is a new concept tunnel rock bolt that expands due to high water pressure and has a mechanism for securing itself to the surrounding rock. 【Features】 ★ Reliable construction without filling materials ★ It secures itself to the surrounding rock with the expansion pressure of the steel pipe, without using filling materials like mortar. Even in areas with water inflow, it secures itself reliably without the influence of cement component leakage. ★ Speedy construction ★ Since no fixing materials like mortar are needed and it secures itself simultaneously with construction, it contributes to shortening the construction cycle and achieving early strength development. ★ High corrosion-resistant rock bolt ★ The entire length of the bolt is treated with high corrosion-resistant plating, boasting high durability. This contributes to the long lifespan of tunnel structures. *For more details, please download the PDF or contact us.
