Self-Drilling IBO Bolt Application

The self-drilling IBO bolt system is an innovative rock reinforcement solution developed especially for weak and unstable ground conditions. Unlike conventional bolting systems, IBO bolts do not require pre-drilling, thus saving time and significantly reducing labor and machinery costs. The hollow structure of the system allows air and water to circulate freely during drilling, which allows the waste material accumulated during the drilling process to be easily removed. When the drilling process is completed, injection starts immediately and the injection fluid passing through the bolt fills all the gaps between the bolt and the ground, ensuring complete integration with the ground.

Another important advantage of this system is that it provides excellent results on weak and unstable ground. It is used safely especially in soft grounds such as clay and gravel and in high-risk areas such as tunnels, excavations and slope stabilization. Simultaneous drilling and bolt placement increases operational efficiency in large projects.

Prominent Features

• Does Not Require Pre-Drilling: Even in difficult ground conditions, the IBO bolt system can be used without pre-drilling. This feature provides speed and efficiency compared to classical methods.
• Ground Safety: During the injection process, the liquid fills all the gaps around the bolt and provides high strength in the ground.
• Time and Cost Savings: It provides significant savings in machine and labor usage and speeds up the operation processes.
• Durability and Flexibility: Rust-resistant versions are suitable for permanent projects, while more cost-effective versions are suitable for temporary projects.
• Chemical Resistance: It guarantees optimum durability with the chemical cement filling in its outer structure.

Areas of Use

Self-drilling İBO bolt has a wide range of uses such as tunnel excavations, dam constructions, slope stabilization, retaining walls and reinforcement of noise barriers. It is used to provide ground stabilization at tunnel entrances and weak tunnel faces, increasing project safety. It also plays an important role in dam constructions, excavation roads and strengthening slopes.

As a result, the self-drilling İBO bolt system is one of the most effective and efficient solutions used in high-risk and weak ground conditions. It is a preferred system in projects as it saves labor, time and cost, and at the same time, it maximizes the safety of the projects.
