Existing Ground <br />Surface <br />Sand Pad if necessary <br />(Not to Scale) <br />Measurement Rod, 1/7' diameter <br />pipe or rebar <br />Casing, 2" diameter pipe <br />(set on plate, not fastened) <br />Coupling welded to plate <br />Settlement Plate, <br />16" x 15' x ! /a" <br />NOTES: <br />1. Install markers on firm ground or on sand pads if <br />needea for stability. Tcke initial reading on top of <br />rod and at adjacent ground level prior to placement <br />of any fill. <br />2. For ease in handling, rod and casing are usually <br />installed in 5—foot sections. As fill progresses, <br />couplings are used to install additional Jengths. <br />Continuity is maintained by reading the top of the <br />measurement rod, then immediately adding the new <br />section and reading the top of the added rod. Both <br />readings are recorded. <br />3. Record the elevation of the top of the measurement <br />rod in each marker at the recommended time intervals. <br />Each time, note the elevation of the adjacent fill <br />surface. <br />4. Read the marker to the nearest 0.01 foot, or 0.005 <br />foot if possible. Note the fill elevation to the <br />nearest 0.1 foot. <br />5. The elevations should be referenced to a temporary <br />benchmark located on stable ground at least 100 feet <br />from the embankment. <br />q <br />GMENGINEER� _ SETTLEME'NT PLATE DETAIL <br />Earth Science - Tennelec; FIGURE 5 <br />
