1. The working principle and characteristics of the seam pipe anchor. The seam pipe anchor is a new type of full-length anchor that actively reinforces the surrounding rock. Its three-dimensional part is a longitudinally slit high-strength steel pipe. When installed on the pipe When drilling a hole with a slightly smaller diameter, radial pressure can be immediately applied to the hole wall throughout the entire length and the friction force that prevents the surrounding rock from sliding down plus the supporting force of the anchor pallet can put the surrounding rock in a three-way stressed state. And achieve rock formation greatness. In the case of blasting vibration and anchorage movement of the surrounding rock, the anchoring force will increase significantly in the later period. When the surrounding rock undergoes significant displacement, the anchor does not lose its supporting resistance. It has better characteristics than the expanding shell anchor.
