Developed the self-drilling lock 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 construction specifications. It is a casing and spacer combined type. The use of a self-drilling method with casing pipes improves construction quality. It is also suitable for construction in narrow areas, as it can be operated with a lightweight drilling machine or manually (using a leg hammer). Features: - A casing combined type self-drilling main construction bolt system using "high corrosion-resistant hollow bolts." - Possible to operate with a lightweight drilling machine or manually. - Ensures reliable grout filling. - Effective for construction in narrow spaces. "Hawk Nailing" is a self-drilling bolt system that uses high corrosion-resistant coated 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 manually (with a leg hammer), making it suitable for narrow areas where large machinery cannot access. ★ We will be exhibiting at the "6th Bridge and Tunnel Technology Exhibition"!
