SPLIT SETS

Ay-Yıldız Engineering Split Set systems are high-strength friction rock stabilizers used to secure rock masses in tunneling and mining operations. Their special slotted steel tube design creates a strong frictional anchor when installed into a borehole that is slightly smaller than the tube’s outer diameter. As the tube compresses along its entire length, radial spring forces develop and provide excellent holding capacity.

Fast ans Simple Installation : Split Sets offer rapid installation in soft, medium and hard rock formations. Once inserted into the borehole, the tube is expanded using high-pressure water, allowing it to grip the rock surface immediately. Their performance is not affected by minor borehole diameter variations, making them highly reliable in challenging field conditions.

Instant Load-Bearing Capacity : As soon as the Split Set is expanded, it locks firmly into the rock and begins carrying load instantly. There is no need to wait for grout or resin to cure, resulting in shorter installation times and improved operational efficiency—especially valuable in unstable ground where immediate support is required.

High Reliability : Ay-Yıldız Engineering Split Sets are manufactured from specially formulated, ductile high-strength steel to ensure reliable performance under varying geological conditions. Their ability to deform and accommodate rock movement significantly enhances underground safety.

Environmentally Friendly Support System : Split Sets require only water for expansion, eliminating the need for chemical additives, grout, or cement-based mixtures. This provides a cleaner work environment and makes the system ideal for environmentally sensitive tunneling projects.
