宋体.> Our company strives for survival by quality and takes customers as our food and clothing parents, and has won a large number of customers. trust. We have signed long-term cooperation with many companies! The company specializes in the production of pipe-slit anchors for mining. Pipe-slit anchor
It is a new type of anchor with full-length anchoring and active reinforcement of surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slots. When installed in a borehole slightly smaller than the pipe diameter When the whole length is reached, radial pressure can be immediately applied to the hole wall and the friction force to prevent the surrounding rock from sliding down, plus the supporting force of the anchor pallet, so that the surrounding rock is in a three-way stressed state and achieves The rock formations are great. In the case of blasting vibration and anchorage movement of surrounding rock, the anchoring force of Song Dynasty
will increase significantly in the later period. When the surrounding rock undergoes significant displacement, the anchor will not lose its support
Song Dynasty resistance.
