Pipe seam anchor Seam pipe anchor Slotted anchor rock friction stabilizer Main specifications
Length
Pipe seam anchor is a new type of anchor with full length anchoring and active reinforcement of surrounding rock. The three-dimensional part is a high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, it can immediately exert radial pressure on the hole wall throughout the entire length and prevent the surrounding rock from sliding down. The supporting force of the upper anchor pallet's supporting plate puts the surrounding rock in a three-way stressed state and achieves greatness of the rock formation.
The anchoring force of the pipe-slit anchor will be significantly increased in the later period when the surrounding rock is anchored due to blasting vibration. When the surrounding rock is significantly displaced, the anchor will not lose its supporting resistance. It is better than the shell expansion. Type anchors have better characteristics.
Main technical performance
Initial anchoring force ~ tons
Pipe ring pull-off load ~ tons
Anchor tube tensile breaking capacity ~ tons
Corrosion resistance is higher than steel ~, conducive to long-term use.
Slit pipe anchors are also called rock friction stabilizers. Slit pipe anchors are highly specialized support supplies. They are advanced materials used for underground culvert roofs and other engineering supports. They have simple manufacturing processes and are easy to use. , in the underground bolting and shot blasting support, it has strong anchoring force, large tensile strength, and strong expansion force, making the entire roof become one.
The meaning and specifications of the product model of the jointed pipe anchor
The product model of the jointed pipe anchor is expressed by the outer diameter/length, where represents the anchor rod. Indicates seam tube type. For example, / represents a seam pipe anchor, its outer diameter is and its length is.
Technical requirements
) The surface of the seam pipe anchor 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.
) The pull-off force of the retaining ring weld, the ultimate tensile strength of the rod, the initial anchor force/, and the load-bearing capacity of the pallet.
, product use
First use a pneumatic drill to drill the anchor hole on the roof, insert the pallet into the anchor rod body, and then use a pneumatic hammer to drive the rod body into the anchor hole so that the pallet and the roof plate are firmly attached. Reality.
When users use anchors, in addition to referring to the above table, the selected drilling diameter should be selected according to the specific conditions of the rock and the standards.
