Installation Instructions for Snap Seal Inclinometer Casing <br /> 4 Pre-Installation <br /> Before beginning the installation, ensure that all equipment, accessories and spares are available: <br /> • Casing and caps <br /> • Spare bottom and top caps <br /> • Spare casing length(s) <br /> • Grout tremie line <br /> • Grout valved bottom cap (if employing this method); c/w spare female grout valve <br /> • Drill rods to weigh casing <br /> • Safety line(if required) <br /> • Clean water supply to ballast casing <br /> • Repair Coupling and Alignment Tool (if required) <br /> • Hand saw <br /> • Casing collar protection (as required) <br /> • Chain or casing clamps <br /> Inspect casing lengths to insure that damage during transit has not occurred. Ensure that the inside of <br /> the casing is clean. To ensure the joint and casing interior will remain clean, only remove the protective <br /> end caps prior to installing the casing. Store the casing horizontally, fully supported, and out of the <br /> sunlight. Number each length, and assemble numerically to avoid errors, and to confirm correct depth. <br /> Do not assemble the casing prior to insertion in the borehole. <br /> Drill the borehole as vertical as possible, preferably within 1 degree. Flush the borehole clean, and verify <br /> that the borehole is fully open to the bottom. <br /> 5 <br />
