Abstract
Description
Technical Field
[0001] This utility model relates to the field of earthwork measurement technology, and more specifically to an engineering earthwork measurement device. Background Technology
[0002] In the process of earthwork measurement, RTK equipment is mainly used for earthwork measurement. RTK carrier phase differential technology is a method of real-time processing of the differential values of carrier phase observations from two measurement stations. The carrier phase data collected by the base station is sent to the user receiver for differential calculation of coordinates. This is a new and commonly used satellite positioning measurement method. Previous static, rapid static, and dynamic measurements all required post-processing to obtain centimeter-level accuracy, while RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It adopts a carrier phase dynamic real-time differential method and is a major milestone in GPS applications. Its emergence has brought new measurement principles and methods to engineering layout, topographic mapping, and various control surveys, greatly improving work efficiency.
[0003] Existing RTK equipment consists of a handheld positioning adjustment rod, an RTK main unit, and a sensor at the bottom. However, existing equipment uses only one sensor at the bottom for positioning during operation. Therefore, during the measurement process, multiple points need to be measured to map the shape of the earthwork surface and then measure the volume of the earthwork. However, when measuring a single point, multiple points need to be measured, especially for curved surfaces. Adding more measurement points to the equipment would be inconvenient for its placement and storage. Utility Model Content

When not in use, the four height measurement sensors 204 can be brought closer together by rotating the rotating sleeve 201 in the reverse direction to save placement space. Then, by placing the RTK equipment body 303 on top of the fixed base plate 301 and rotating the rotating knob 306 to drive the threaded rod 305 to rotate, the telescopic positioning plate 304 moves closer to the fixed base plate 301 under the positioning of the positioning rod 307 to fix the RTK equipment body 303. When the equipment is not in use, the RTK equipment body 303 can be removed and stored separately.
