General Information
SAAV is designed to enable faster and simpler installation with direct installation in casing sizes from 47 mm to 100 mm inside diameter, as well as 27 mm ID conduit. SAAV can be installed into existing casings, even those that are too distorted for conventional use, which eliminates the need to drill new boreholes when converting from manual to automated monitoring. SAAV is available in 2501 mm and 500 mm segment lengths and can be installed vertically, horizontally, or in an arc. SAAV’s rugged joint design enables the instrument to zigzag into various sizes of standard inclinometer casing sizes. A spring box at the top holds the joints firmly in contact with the casing, without any additional grouting. This cyclical installation method is unique to SAAV (patent pending). Software tracks the medial axis within the casing in 3D to produce traditional inclinometer data plots. Silent segments and extension tubes—two technologies specific to SAAV installed vertically/vertical SAAV installations—allow greater flexibility and control to place SAAV’s sensorized segments in a zone of interest. Clients may choose SAAV for vertical installation in 27 mm ID conduit or horizontally in schedule 80 (60 mm OD) casing, which can be configured at the time of order or changed in the field with the use of a conversion kit (purchased seperately). SAAV installed in an arc to monitor convergence feature a new installation method. SAAV sold for convergence applications are inserted into 21 mm ID PVC flex conduit at the factory and coiled onto its shipping reel, which arrive ready for the client to install directly to the tunnel wall with U-clamps.
