Developed the self-drilling rock bolt system "Hawk Nailing" as per this specification.
Self-drilling bolt system used in conjunction with casing pipes. Achieves reliable grout filling. A lightweight and compact system suitable for construction in narrow spaces.
◎This is a self-drilling "high corrosion-resistant hollow bolt" for the main specification. It is a casing and spacer combined type. The use of a self-drilling method with casing pipes improves construction quality. It is also possible to use lightweight drilling machines or manual labor (leg hammers), making it suitable for construction in narrow areas. Features: - A self-drilling main bolt system using "high corrosion-resistant hollow bolts" combined with casing. - Construction is possible with lightweight drilling machines or manually. - Ensures reliable grout filling. - Effective for construction in narrow spaces. The "Hawk Nailing" is a self-drilling bolt system that uses high corrosion-resistant plated hollow rock bolts (with a diameter of 32) combined with casing pipes. It enables reliable grout filling, which has been a challenge in previous self-drilling methods. Additionally, it allows for construction using compact drilling machines or manual labor (leg hammers), making it feasible for construction in narrow spaces where large machinery cannot access.
