SW-PCD anchor system(Permanent, Compressive and Distributive)
SW-PCD anchor system is a compressive-distributive type permanent anchor, developed and commercialized by SAMWOO. Unbonded P.C. strands are used as tension members, having outstanding corrosion and rust protection. The block also has sealing structure that has outstanding corrosion protection.


SW-PCD permanent anchor system separately confines the strands with grips to maximize the performance of the strands, and since it does not apply concentrated load to the ground, being a compressive-distributive type anchor, it can minimize the creep due to the load, and also, the allowed anchoring force can be adjusted according to the ground condition. Also, since its fixation location is flexible, it can secure the necessary load easily as well as re-tension, even if the bearing plate or block subsides due to the lack of the supporting force of the main floor.

Outstanding corrosion protection process
- Block: Separately confines the strands with Grips, maximizing the performance of the strands
- Tension member: general strand and coated strand, perfect corrosion resistance (grease) and protection with the H.D.P.E Hose
Compressive distributive type System
- Minimizes the creep due to load by not applying concentrated load to the ground
- Prevents free anchor length confinement by perfectly protecting the tension member
- The allowed anchoring force can be adjusted according to the ground conditions

SW-PCD anchor system structure/specification
To strengthen the merits of the compressive-distributive type anchor, we separately confined the strands bound to the block. Such separated confining system is a system that bounds the insert to the inside of the Grip, assembles the strand, and completely bounds by pushing it into the device with a small diameter.

SW-PCD permanent anchor construction order



SW-PCD anchor system - guideline
1. Take care not to tear or damage the strand coating. If the strand corrodes through the damaged part, it is difficult for the permanent anchor to fully perform its role.
2. Avoid soiling the anchor body with dirt or alien substances when moving the anchor body at the site. It is difficult to secure anchoring force, not being able to apply compression to the grout.
3. Take care to prevent the destruction of the drilled hole when inserting the anchor body. It is difficult to secure anchoring force, for the grout is yet not filled in.



Major achievements on SW-PCD anchor system in Korea
SW-PCD anchor system, a corrosion-protection permanent anchor system, was first commercialized in 2003, and is most widely used for various permanent purposes such as supplementation and stabilization of cut sections at new road or additional construction sites, stabilization of slope, supplementation of revetment, stabilization of tunnel pit mouths, and lift up resistance based on its outstanding constructability and economic efficiency.
