Installation anchoring technique

The anchoring technique will be explained by describing a typical installation day using the example of a composite liner construction, though the span of events within an installation day can change quite broadly. This will then be a somewhat simplified and idealized representation, but all key aspects will be clearly explained. Fig. 9.8a and b schematically shows the different installation phases, which comprise the anchoring technique. 

Fig. 9.12b. This photograph shows that the anchoring technique provides complete flatness even in critical areas (slope toe and pipe penetration constractions). In such places where hand-welded extrusion fillet seams occur in higher frequency and standing leachate can be expected, special care and high technical installation skills are required. Only experienced, particularly qualified and well-equipped specialist installation companies can master this task. Courtesy Schicketanz Consulting Engineers, Aachen...

A sleeve may be used to provide an unbonded length for tensioning (Figure 4.5). Depending on the embedment depth and diameter of the anchor, various techniques may be used to facilitate installation of the anchor using the various grout types.
