Split Rock Friction Anchor

Jiufu friction anchor bolt is a threaded anchor system designed for underground engineering support. It is suitable for use in tunnels and mines, especially in machines, walls, or rocks, and can also be used in metal mining operations. Its operating principle is to improve the stability and safety of rocks by tightening when lateral ground movement occurs, prevent unstable situations such as rock collapse or crushing and soil landslides, and ensure the safety and stability of engineering projects.

Product Description

Split rock friction anchor system is also a split anchor system, which is composed of high-strength steel pipe (alloy steel strip) or thin steel plate and a perforated tray. From the appearance, it can be seen at the end of the anchor rod. A U-shaped cross-section and longitudinally grooved bolt. It is mainly used for support engineering projects and can be used in underground copper mines, recent mining, tunnel construction, bridges, dams and other infrastructure projects. In addition to the above areas, it can also be used to stabilize the ground and prevent erosion. The installation method of friction bolts is simple and the difficulty coefficient is low. It is an important advanced material in the field of engineering support projects today.

Product Installation

Installation method:

1.Drill holes according to specifications: Use a rock drill to drill holes in the ceiling or walls. The diameter of the hole will be slightly smaller than the diameter of the bolt.

2.Pay attention to keeping clean: Compressed air is recommended to clean the holes and remove dust and loose particles.

3.Insert the bolts: Insert the split friction bolt into the hole that exactly lines up with it, making sure the tray is resting on the surface of the ceiling or wall.

4.Installation: Place the installation tool on the bolt head and tap with a hammer until the bolt is fully installed. Tool and hammer strikes must be perfectly aligned with the bolt axis to avoid distortion. The bolt head deforms slightly to make contact with the ceiling or wall surface, creating friction that helps maintain stability.

5.Verification check: Verify bolt installation to ensure it is placed correctly and has the proper tension.

Product Advantages

1.Made of high-strength steel pipe, it is a new type of anchor.

2.Optional galvanized and stainless steel materials.

3.Suitable for mining support and other fields to improve rock stability and safety.

4.Versatility: Whether it is mining, tunneling or other underground projects, friction anchors can adapt to various complex geological conditions.

5.Easy installation: The installation process is simple, saving time and labor costs as well as the cost of composite materials. Simplicity of installation ensures efficiency without compromising performance. Friction bolts are therefore a cost-effective option.

6.Immediate load-carrying capacity: Friction bolts provide immediate load-carrying capacity after installation due to the friction generated between the bolt and the surrounding rock.

7.Reduced risk of accidents: Friction bolts are less likely to cause accidents because they don’t need to be hammered into place. This reduces the risk of rock fracture and reduces worker exposure to vibration and dust.

8.No need for anchoring agent.

Product Aarameters

Hebei Jiufu split rock friction anchor system, also known as split anchor system, consists of high-strength steel pipe (alloy steel strip) or thin steel plate. From the appearance, a U-shaped cross-section and longitudinal groove bolts can be seen at the end of the anchor. It is mainly used for support engineering projects and can be used in underground copper mines, recent mining, and infrastructure projects such as tunnel construction, bridges and dams. In addition to the above fields, it can also be used for ground stability and erosion prevention. Friction bolts are simple to install and have low difficulty coefficients. They are important advanced materials in today's engineering support projects.

Components:

1.High-strength, high-elastic steel pipe with longitudinal gaps

As a new type of anchor, the friction bolt rod body is made of high-strength, high-elastic steel pipe or thin steel plate, and is slotted longitudinally along the entire length. The end of the rod is made into a cone for installation.

2.Matching tray

The split kit can also have a flat or curved plate at one end to distribute the rock load over a larger surface area, thereby increasing its support capacity. Once the bolt is inserted into place, concrete masonry, filler or grid can be placed to complete the support and stability.

There are four different types of commonly used pallets to choose from.

3. Welding ring

Used to prevent the pallet from sliding off.
