Background
The work of calibrating the slope (namely a waist line) of the finished roadway or chamber ground in coal mine work or other industries is common and troublesome, the slope calibration method is various, the design slope is calculated and measured by instruments such as a total station and the like, and then the slope is given by using a laser indicating instrument; another method is to give a reference wale to a fixed wall surface. The method of calibrating the waist line by using the total station is troublesome in construction, and the laser indicator cannot calibrate the whole bottom plate or lane side, so that the limitation is large, and the waist line needs to be given on a relatively fixed wall surface for reference. For a long time, the wall surface waist line is given or calibrated by drawing a line through an angle gauge or by measuring and calculating through a total station, so that the measurement and calculation are very complicated and errors are easy to occur. Most of the existing gradiometers for engineering on the market are mechanical or the level laser can not accurately calibrate the gradient, and the gradiometer has few or even no functions, so the gradient calibrator is designed by adding reference data to measurement experiences for many years.
