Hollow Bar Anchor Bolt

Hollow bar anchor is pull rod that transfer anchored structures or geotechnical loads to a stable formation. Pressure grouting of the anchor bar through the hollow bar body can achieve the purpose of consolidating the broken rock mass, blocking the groundwater and the anti-corrosion of the rod body, and rapidly forming the supporting force to control the stability of the surrounding rock.

Hollow bar anchors are mainly produced by high-strength seamless pipes.

Threaded hollow bars are widely used in construction, mining, and tunneling industries for various applications. Some common uses and advantages of threaded hollow bars include:

1. Ground stabilization: Threaded hollow bars are used for ground stabilization in rock and soil. They are inserted into the ground and grouted to provide support and reinforcement, particularly in areas prone to landslides, collapsing walls, or sinkholes.

2. Anchoring systems: Threaded hollow bars can be used as part of anchoring systems to provide stability and support to structures. They are commonly used to secure retaining walls, slopes, and deep excavations, minimizing the risk of structural failure.

3. Foundation reinforcement: Threaded hollow bars are used to strengthen foundation structures in construction projects. By embedding the bars in concrete or soil, they increase the load-bearing capacity of foundations and prevent settlement or shifting.

4. Tunneling and mining: Threaded hollow bars are essential in tunnel construction and mining as they provide ground reinforcement and support to prevent collapse or cave-ins. The bars can stabilize the rock or soil while also serving as the base for other support structures.

Advantages of threaded hollow bars:

1. Versatility: Threaded hollow bars come in various sizes and lengths, making them suitable for a wide range of applications. They can be easily customized to fit specific project requirements.

2. High load-bearing capacity: These bars are designed to withstand heavy loads and provide substantial support and reinforcement to structures. They can effectively distribute and transfer the load to prevent any structural damage.

3. Corrosion resistance: Threaded hollow bars are often made of high-strength steel or other materials with excellent corrosion resistance. This makes them suitable for use in harsh environmental conditions, including marine or underground applications.

4. Installation efficiency: The threaded design of these bars allows for quick and easy installation. They can be installed with various types of drilling equipment, reducing labor and installation time.

5. Reliability and durability: Threaded hollow bars are known for their strength and durability, ensuring long-term stability and performance. They are built to withstand heavy loads, vibrations, and external forces.

Overall, threaded hollow bars offer a reliable and efficient solution for ground reinforcement and structural stability in various construction and mining applications.
