Working Principle of Songti Pipe Seam Anchor
Songti installs the pipe seam anchor in a borehole smaller than the pipe diameter. At this time, three forces will be exerted on the surrounding rock. One is the force on the surrounding rock. The radial pressure on the hole wall within the entire length of the pipe seam anchor is friction, which is used to prevent the surrounding rock from sliding down, and the other is the supporting force of the pipe seam anchor pallet. These three forces make the surrounding rock more stable.
Technical features of Songti pipe joint anchors
, raw materials are made of high-strength alloy strip steel
, the simplest installation
No anchoring agent required
, friction between anchor rod and rock mass It has high strength
, high shear resistance and tensile strength
, and is equipped with a high-strength pallet, which is evenly stressed
and the height of the tunnel is greater than the length of the anchor rod.
Technical requirements for pipe seam anchors in Song Dynasty
The surface of seam pipe anchors should be smooth and free of serious strain and rust. Welds should be free of cracks, pores and slag inclusions, and burning through the pipe wall is not allowed. The pallet should be able to move freely on the pole. It is appropriate that the baffle ring interface and the pipe seam opening are misaligned with each other.
, retaining ring weld pull-off force, rod ultimate tensile strength, initial anchor force pallet bearing capacity.
Song style pipe seam anchor technical performance
, initial anchoring force ~ tons
, pipe ring pull-off load ~ tons
, anchor pipe tensile breaking capacity ~ tons
, corrosion resistance is ~% higher than steel, which is conducive to long-term use.
How to use the Song Dynasty pipe joint anchor
Determine the anchor hole position according to the design requirements, and use a drilling tool to drill the hole.
Use compressed air to blow away the rock powder in the hole.
. Install the anchor plate on the rod body, and drive the anchor rod into the hole with an impact drill.
