Installation
Magnetic Extensometers
1
Flush debris from borehole. Fix datum magnet to bottom section of access pipe. Number other
sections of pipe for installation. Fix spider magnets to each section. Label release cords, coil, and tape
to pipe.
2
Attach grout hose to bottom section of pipe. Lower pipe into borehole. Add next section of pipe. Seal
pipe joint. Carefully remove safety ties from magnet legs, then push pipe into borehole. Arrange
release cord so legs are not released accidentally. Add additional sections of pipe as required. Check
magnet depths.
3
Begin grouting. Release magnet legs as level of grout rises. If drill casing used, pull casing before
releasing legs. Continue until all spider magnets are released and borehole is filled with grout.
4
Terminate as specified. Obtain good initial readings, then hand over to client.
