SW - PTF Anchor

SW-PTF anchor system
SW-PTF anchor system is a tensile-frictional type permanent anchor system, which has been widely used in Korea and overseas, with sufficient research results and application history. It has outstanding corrosion and rust protection, and is used for various permanent purposes such as lift up resistance, supplementation and stabilization of cut sections at new load and additional construction area, stabilization of slope, supplementation of walls, and stabilization of tunnel pit mouths based on its advanced quality obtained through standard production process.

There are two types according to the form of the Nose-con; an open type and a closed type.

SW-PTF anchor construction order

SW-PTF anchor system - guideline
1. Avoid soiling the anchor body’s external duct with dirt or alien substances when moving the anchor body at the site. It is difficult to secure anchoring force.
2. Take care not to damage the duct (Water proof and corrosion protection protection is difficult)
3. Conduct induced drainage to maintain the underground water level lower than the mat’s bottom, to prevent underground water leakage into the sleeve. If underground water leaks, water-proof quality is difficult to achieve.
4. Take caution in the falling speed, to prevent strong falling into the drilled hole when inserting the anchor. If the Nose-con is damaged due to the shock caused by falling into the drilled hole, external grouting and securing the anchoring force become difficult.

Major achievements on SW-PTF anchor system
SW-PTF anchor system, with its outstanding corrosion and rust protection structure, has been widely used domestically and overseas for various permanent purposes such as lift up resistance, supplementation and stabilization of cut sections, stabilization of slope, supplementation and stabilization of revetment, stabilization of tunnel pit mouths, and lift
