Description

Technical Field

[0001] This utility model relates to the field of flatness measurement technology, and in particular to a device for rapidly measuring the flatness of the ground. Background Technology

[0002] In many fields such as civil engineering, building construction, and geological exploration, ground flatness measurement is a crucial step in ensuring project quality and safety. Traditional ground flatness measurement methods mainly rely on leveling instruments to perform multi-point elevation measurements.

[0003] However, although this method has high accuracy, it has significant drawbacks. Specifically, the leveling instrument needs to measure the elevation at multiple points and then use complex data processing to evaluate the flatness of the ground. This process is time-consuming and cannot measure the flatness of the area.

[0004] With the continuous expansion of engineering construction scale and the increasing requirements for engineering quality, there is an urgent need for a device that can measure the flatness of a region. Therefore, a device for rapidly measuring ground flatness is proposed. Utility Model Content

The measuring component includes a plate-type distance measuring element, which is provided with a snap-fit ​​part for connecting to a workbench. The plate-type distance measuring element is used for measuring ground flatness. The output end of the plate-type distance measuring element is provided with a data processing unit, and the output end of the data processing unit is provided with an alarm unit.

[0009] Preferably, the data processing unit includes:

[0010] A support tube is provided on the top of the workbench;
