S302, corresponding virtual control points are established on the construction project three-dimensional model according to the real-time position information of the control standard points.
In the step, the positions of all control calibration points are marked in the three-dimensional model of the construction project according to the real-time position information of the control calibration points.
S303, calculating the coincidence ratio of the virtual control point and the construction project three-dimensional model.
In this step, for each control calibration point, the theoretical coordinates of the control calibration point in the three-dimensional model of the construction project are fixed, so that the superposition condition of each virtual control point and the three-dimensional model of the construction project can be obtained by directly calculating the difference value between the real-time position information of the control calibration point measured in real time and the theoretical coordinates of the control calibration point, and the superposition degree is determined according to the deviation value, namely the superposition degree is used for representing the deviation amplitude, the larger the superposition degree is, the better the explanation quality is, the smaller the superposition degree is, and the worse the explanation quality is.

In this step, after calculation, the degree of overlap is obtained, and the position of each control point is not completely fixed, but may fluctuate within a certain range, so that when the deviation amount of the degree of overlap is small, no risk is caused, and if the degree of overlap value is low, it is indicated that there is a quality problem, and an alarm needs to be issued.
As shown in fig. 4, as a preferred embodiment of the present application, the step of determining whether quality problems exist in each virtual control point according to the difference between the calculated value of the overlap ratio and the preset value specifically includes:
s3041, comparing the difference between the calculated value and the preset value with a preset quality judgment table to obtain a comparison result, wherein the quality judgment table comprises the corresponding relation between the difference and the quality problem.
S3042, determining quality problems according to the comparison result.
In this step, the quality determination table is preset, so after calculating the overlap ratio, the difference between the calculated value and the preset value is directly used as a comparison source, and then is compared with each item in the quality determination table to determine the quality problem, for example, the overlap ratio is 0-0.95,0.95-0.98,0.98-1.0, which is three types of component failure, component failure possibility and component stability respectively, and the quality problem is determined by the section where the overlap ratio is located, and of course, the overlap ratio can also be a numerical section, for example, for the length of the component A, the overlap ratio is 0-15m,15-19m and 19-20m respectively belong to three different quality problems.

S403, obtaining vertical loads of each point in the manual construction area.
In the step, the vertical load distribution condition of the current manual construction area is analyzed according to the vertical load of each point.

s501, determining the type of the quality problem according to the quality problem.
In this step, the type of problem is determined according to the quality problem, for example, if no side wall displacement occurs in the foundation pit, it is indicated that there is no quality problem, if slight displacement occurs, it is indicated that there is a tendency of instability, it is necessary to reinforce it, and if the displacement is larger, it is indicated that complete instability is about to occur, and it is necessary to evacuate personnel.
