Song Dynasty.>Pipe-slit anchor
It is a new type of full-length anchor that actively reinforces the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slits. When installed in a When drilling a hole with a slightly smaller diameter, radial pressure can be immediately applied to the hole wall throughout the entire length and friction to prevent the surrounding rock from sliding down. In addition, coupled with the supporting force of the anchor pallet, the surrounding rock can be placed in three positions. To the state of stress and achieve rock formation greatness. 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.
