Background
The slope is a slope surface with a certain slope, which is made in the process of excavation, is used for guaranteeing the stability of foundation pit, roadbed or mountain slope, the detection of the slope of the soil slope is a basic detection item specified in the quality inspection and evaluation standards of foundation pit and highway engineering, the slope of the slope depends on geology, hydrologic conditions and the filling height of the roadbed, and once the slope value of the slope is determined, the problems of increased occupied area and higher economic cost of cross section are caused if the slope value exceeds a specified value in construction; if the slope reaches a specified value, the stability of the roadbed is directly affected, and hidden quality hazards are buried, so that the accurate measurement of the slope of the foundation pit in construction can not only enable the slope to be rapidly formed and save the construction time, but also effectively ensure the stability of the foundation pit;
in the traditional measuring method, the slope is calculated after the slope of the foundation pit is measured by using a flower rod and a tape, and because the angles of the slopes are often different, two or more persons are required to cooperate during measurement, the constructor usually uses the flower rod to cooperate with the tape to measure the corresponding size of the slope, and then calculates the slope according to the size; later, the method is also a mainstream measurement mode at present, constructors use a level gauge or a total station to periodically detect the slope gradient in order to improve the detection efficiency, but because the number of on-site constructors is limited, the constructors cannot monitor the construction process on site in real time, and because the single slope-releasing angle is larger when the excavator releases the slope, the problem that the slope is more or less released easily occurs when the interval period is longer, and reworking treatment is needed; when the level gauge is used for detection, two numerical values are required to be measured, and the gradient of the current excavation slope can be obtained after right-angle operation, so that the whole measurement process is complicated and is not concise; meanwhile, when the slope angle calculation device is used, the calculated slope angle is not necessarily the accurate slope due to different placement positions of the leveling rod and the prism, so that the slope angle of the excavated slope can not be accurately reflected, and potential safety hazards are caused;
