Friction Bolt Anchor – Multi-Use

Jiufu has recently introduced a tensile testing machine, which can test the yield force and fracture force of raw materials during the production process, effectively ensuring the raw material quality of mine friction bolts.

Split anchor, also known as split anchor stabilizer, is an indispensable advanced material in underground mine support. It is a very specific support product, an advanced material used for roof support in projects such as underground copper or gold mining.

Product Description

Describe:

47mm friction bolt and split set is mainly used as a primary support in mechanised jumbo development and production mining.

It is one of the standard friction bolt and split set widely used in worldwide project of mining, tunnel and dam as rock support material.

Product Features:

1. The raw material is made of high-strength alloy steel strip.

2. Easy to install.

3. No anchoring agent is required.

4. The friction between the anchor rod and the rock is high.

5. Has high shear and tensile strength.

6. Equipped with high-strength plates.

Application areas are as follows:

In different fields of application, from mining to tunnel construction and infrastructure, bolts are an effective solution for rock support and stabilization.

1. Underground mining.

2. Infrastructure.

3. Tunnel construction.

4. Erosion control.

Friction Bolt Anchor – Multi-Use

Composition

1. The JIUFU Friction Bolt is manufactured from high strength steel tube which has a slot along its entire length. A ring, or collar, is welded on the outer end to hold a domed plate to the rock surface.

2. The 47mm Friction Bolt is suitable for installation with hand held rock drills.

3. Friction bolts can be load tested by fitting a special ring to the bolt prior to its installation. Pull tests can then be conducted with a hollow ram hydraulic jack.

4. Further corrosion protection can be provided by hot dip galvanizing.

Installation

Friction Bolt is a new type of anchor rod for full-length anchoring, which main part is a high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, The radial pressure is applied to the hole wall and the friction to prevent the sliding of the surrounding rock within the full length, plus the supporting force of the Mining Plate, So that the surrounding rock is subjected to forces in three directions to ensure the stability and safety of the surrounding rock.

When the surrounding rock is significantly displaced, the anchor rod does not lose its supporting resistance, and it has better characteristics than the expansion shell Rock Bolt.

Advantages

1. Friction bolts are simple to operate and easy to use. It has anchored underground anchor and shotcrete support.

2. It has strong strength, high tensile strength and strong expansion force.

3. Hot dip galvanizing provides further corrosion protection.
