Product Description
Split set is a new type of full-length anchorage and active reinforcement of surrounding rock. Its three-dimensional part is a longitudinally-slotted high-strength steel pipe. When installed in a drilling hole slightly smaller than the diameter of the pipe, it can immediately exert radial pressure on the hole wall and prevent the friction of surrounding rock from sliding down within the full-length range, plus the bearing force of the anchor tray plate, so that the surrounding rock is in a three-way stress state. And achieve rock stability.
2. The installation is the easiest;
3. No anchoring agent required;
4. The friction between the bolt and the rock mass is large;
5. It has high shear and tensile strength;
6. Equipped with high-strength pallet, the pallet is evenly stressed;
