As an important part of coal mine roadway support, split set stabilisers not only have a beautiful appearance, but also have high strength compression resistance. So what are the main factors that affecting the anchor force of split set stabilisers?

The anchor force of the split set stabiliser is related to many factors. Within a certain range, the greater the elastic deformation stiffness and the amount of elastic deformation of the slotted steel pipe, the elastic deformation of the borehole wall along the longitudinal length of the slotted steel pipe is generated. The greater the radial pressure, the greater the anchor force of the split set stabiliser. The split set stabiliser is a full length anchor, which provides anchoring force immediately after installation. The split set stabiliser anchor force will gradually increase as the surrounding rock deformation of the roadway increases.

The well-known conventional split set stabiliser body is a high-strength steel pipe that is slit along a full length longitudinally rolled from thin steel strip. The cross section of the seam pipe is a ring "C" with a gap. The working principle is to use external force to drive the split set stabiliser into a rock or soil borehole with a diameter smaller than the outer diameter of the anchor body by 1-3 or directly into the soil layer. The seam pipe is compressed, and the outer wall of the pipe and the hole are drilled. The hole wall is squeezed tightly; the elasticity of the longitudinally slitted steel pipe is used to generate radial pressure on the hole wall to cause friction resistance between the anchor rod and the hole wall over the full length of the rod body, plus the support force of the outer tray of the anchor rod, So as to strengthen the rock and soil to achieve the purpose of stable support.

The above are the main factors that affecting the anchor force of split set stabilisers. If you have any needs, please contact us!
