Description
Technical Field

[0002] The ground level surveying instrument is also called a level. It uses a horizontal line of sight to measure the height difference between two points on the ground to measure the ground level. The main components are a telescope, a tube level or compensator, a vertical axis, a base, and a foot screw. According to the structure, it can be divided into a micro-tilt level, an automatic level, a laser level, and a digital level, also known as an electronic level. According to the accuracy, it can be divided into a precision level and an ordinary level.
[0003] However, in actual use, the existing levels and tripods have conical bottoms and are placed on flat ground and in windy conditions.

In some special cases, in order to ensure smooth completion within the construction period, the level must work even on rainy days. Although the level has a certain degree of waterproofness, when used on rainy days, once water accidentally enters the detector, it may cause damage to the level and inaccurate test results.
