[0002] In the construction process, excavation of foundation pit is an inevitable link, and it is also the most basic and important construction link of a high-rise building.

[0003] During the foundation pit excavation process, foundation pits of different depths have different slope ratios. At present, the more common slope brushing method on the construction site is to sprinkle extremely cold upper and lower lines with white lime, and then use excavation equipment to brush the slope.

However, the white lime sprinkled on the lower mouth line during the excavation process is easily covered. Since the workers lack corresponding positioning when measuring the slope, they measure different slopes on the same slope, which leads to inconsistent overall slope angles. Summary of the Invention
