SAMWOO Geotech Co., Ltd. has been endeavoring to be the leading company in the ground anchor industry for over 28 years. It is the first company to obtain ISO 9001 certification in the field of ground anchor design, production, and additional services in Korea. Ground anchor industry
Temporary anchor SAMWOO SW-RCD Anchor is a load distributive compression type removable anchor that offers a complete solution where anchorage systems required to be removed once they become redundant. Often city municipalities and the like object to the obstructions left in the ground beyond the completion of construction for fear that they will conflict with future developments or seek third-party approval. The SW-RCD anchors are cost-effective solutions where the use of conventional tieback anchors is forbidden or discarded due to logistical or practical site constraints. The entire steel strand can be quickly and easily removed or reengaged with limited site access. Once simply rotate the strand to release the wedges which are fixed at the end of the anchor body, the entire steel strand is easily withdrawn through the PE sheath leaving the small aluminum anchor body. The removal process is generally done by hand. Since their initial development, these anchors have been employed in numerous projects around the world to provide lateral support to temporary sheeting and shoring conditions.

Principles of SAMWOO SW-RCD Anchor Removal
Rotate the steel strand clockwise and release the wedge.
Manually remove the steel strand separated from the wedge.
Guidelines of SAMWOO SW-RCD Anchor
Pre-grouting (1st) should be done through the borehole before the installation of the SW-RCDanchorand the 2nd grouting (filling the borehole) can be done by pulling out the casing.
The compressive strength of the grout should be over 30 MPa for proper load transfer through the anchor body during the stressing process.
Stressing for each strand with mono jacks is strongly recommended avoiding any excessive load concentration to shorter strands. Step-by-step stressing with one normal jack could be applied as an alternative without mono jacks to cover the elongation gap between the strands with different length.
Each anchor body should be cleaned without any contamination before installation.
The steel support should be combined only with the 1st anchor body before installation to avoid dirty materials in the bottom of the borehole.
PE sheath should not be damaged during handling and installation in the job site to avoid any grout infiltration to the damaged sheath.
