The method for constructing a special-shaped ground-connected wall with mud wall protection according to claim 1, characterized in that: Under the condition of determining the adjustment method of trenching construction, the trenching speed of the milling machine is determined to be 5m / h-7m / h based on the comparison result that the curvature change rate of the guide wall is less than or equal to the preset curvature change rate, or the trenching depth of the milling machine is determined to be 2m-5m based on the comparison result that the curvature change rate of the guide wall is greater than the preset curvature change rate, and the trenching parameters are determined to be unqualified according to the comparison result that the fit between the mud and the trench is less than or equal to the preset fit.
9. The method for constructing a special-shaped ground-connected wall with mud wall protection according to claim 8, characterized in that: Under the condition that it is determined that the grooving speed is unqualified, it is determined to increase the grooving speed by a preset speed adjustment coefficient based on a comparison result that a difference between the fit degree and a preset fit degree is less than or equal to a preset difference.
10. The method for constructing a special-shaped ground-connected wall with mud wall protection according to claim 8, characterized in that: Under the condition that it is determined that the grooving depth is unqualified, based on the comparison result that the difference between the fit degree and the preset fit degree is greater than the preset difference, it is determined to increase the grooving depth by a preset depth adjustment coefficient.
