<P>PROBLEM TO BE SOLVED: To provide a measuring device of an earthwork construction surface capable of easily seizing a quantity of required sediment at ground leveling work by precisely measuring construction accuracy of a ground leveling surface in real time. <P>SOLUTION: This measuring device has GPS antennas 2a and 2b for detecting a position and a longitudinal directional inclination of heavy machinery 1, and a roller inclination sensor 4 for detecting a roller attitude of the heavy machinery 1, and has an on-vehicle control part 5 for inputting a signal from the GPS antennas 2a and 2b and the roller inclination sensor 4, a central control part 6 linked with the on-vehicle control part 5 by radio data, and display parts 7a and 7b connected to the central control part 6 or the on-vehicle control part 5. The on-vehicle control part 5 and the central control part 6 arithmetically operate the absolute height of the heavy machinery 1 by offsetting an inclination component of the heavy machinery 1 from the inputted signal. A difference between the absolute height of this actual ground leveling surface and the ground leveling surface height on a plan and a quantity of cut banking are displayed on the display parts 7a and 7b. <P>COPYRIGHT: (C)2003,JPO |
