Surveyors elevation measuring stick and method

摘要

The civil engineering elevation measuring stick for use in a laser elevation measuring system includes a primary pole with a top end, a bottom end at least four flat side walls. A top end cap, a bottom end cap are attached to the primary pole. A secondary tubular pole telescopically receives the primary pole. Bearings support the secondary tube for sliding movement relative to the primary pole between the top and bottom end caps. A laser beam receiver mounting surface is provided on the secondary tube. A measuring scale is fixed to the primary pole in a location that permits the direct measurement of the deviation between the elevation of a measured surface and desired grade surface.
