In the early 1970s, by Professor James Scott in the USA and Solan in the UK, split sets are widely used to reinforce rock masses because of their unique mechanical properties and many benefits.

A split set is an anchor rod commonly used in soil mechanical support structures. Its structure is slightly different from ordinary bolts, and its main feature is that a filling link is formed between the pipe joint and the soil, and the tension of the anchor is transmitted through this link.

Structural characteristics of the split set

1. Raw material is high-strength alloy strip steel.

2. Easier installation.

3. No need for an anchoring agent

4. The friction between the bolt and the rock mass is large

5. High shear and tensile strength

6. Equipped with a high-strength tray, the tray is evenly stressed

7. The height of the roadway is greater than the length of the anchor.

Combined with the structural characteristics of the split set, it is not difficult to find that the advantage of the split set is that it can better combine with the soil, and the tension of the anchor can be relieved through the filling process, making it more stable and reliable. In addition, this type of anchor bolt also has the advantages of easy construction, convenient construction, and environmental protection, so it is widely used in various soil mechanical support projects. In practical applications, split sets are often used for weak or loose soil support, such as landslides, rock avalanches, steep slopes, and other occasions.

The working principle of the split set

The split set is a full-length bolt that actively reinforces the surrounding rock. The major part is a high-strength alloy steel pipe with longitudinal slots. When installed in a hole slightly smaller than the diameter of the pipe, it can immediately apply radial pressure on the hole wall and friction force to stop the sliding of the surrounding rock at its full length, together with the bearing force of the anchor tray pallet, thus putting the surrounding rock in a three-way force state and achieving rock stability.

In short, as a commonly used soil mechanical support structure, the split set has the advantages of simple structure, easy construction, wide temperature range, and environmental protection. It is suitable for soil mechanical support projects in various situations. Its features make it popular in the modern construction field, and it is a reliable, efficient, and economical way of engineering support.
