The Composition Of Pipe Joint Bolt
Pipe joint bolt is a new type of bolt with full length anchorage and active reinforcement of surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal cracks. At the same time, the tray plate of the bolt also has a certain bearing force, so that the surrounding rock is in a three-way stress state and the rock formation is stable.
Working Principle Of Pipe Joint Bolt
When the pipe joint bolt is installed in a hole smaller than the pipe diameter, three forces will be applied to the surrounding rock, one is the radial pressure on the hole wall within the full length of the pipe slotted bolt, the other is the friction force to prevent the slide of the surrounding rock, and the other is the supporting force of the tray plate of the pipe slotted bolt. These three forces make the surrounding rock more stable.
Characteristics Of Pipe Joint Bolt
1.High strength alloy strip steel is used as raw material;
2. The simplest installation;
3. No need for anchoring agent;
4. The friction between the bolt and the rock mass is large;
5. With high tensile strength;
6. Equipped with high strength pallet, pallet force is uniform.
