It is an anchor application; which consists of tendons having different bond lengths in one borehole. The Single Bore Multiple Anchor system can be either used as permanent or temporary applications with the ability to reduce the quantity of anchors when compared to the conventional anchor systems.
SOIL / ROCK ANCHOR
Soil and rock anchors are composed of a bonded length, a stressing length and an anchor head. The bonded and stressing length parts are prepared prior to installation and the anchor head is placed before stressing of the anchor. The anchors are usually made of seven-wire pre-stressing 0.6’’ steel strands. The required number of strands at each anchor will be bunched and will be placed around spacers, which are used to ensure a grout cover around each strand in the fixed part of the tendon.
