The invention relates to a settlement reinforcement method for an independent foundation of a building brewing workshop. The settlement reinforcement method comprises the following steps that S1, grouting holes are formed, wherein one grouting hole is formed in one side of each stand column, and the depths of the grouting holes are determined according to the geological condition; S2, observationholes are formed, wherein the observation holes are formed in one sides, away from the grouting holes, of the stand columns, the observation holes are drilled to the position below a bearing platform,the observation holes are located in the outer edges of contour lines of pile foundations, on the sides, away from the grouting holes, of the stand columns, guide pipes are inserted into the observation holes, and monitoring devices used for detecting the grouting heights and diameters are arranged at the top ends of the guide pipes; and S3, grouting reinforcement is conducted, wherein grouting is conducted in the grouting holes to reinforce the independent foundation, during grouting, pressure grouting is conducted firstly, then permeation grouting is conducted, and whether grouting is completed or not is judged according to the monitoring devices. The method has the advantages of being suitable for construction in a narrow area, simple in process and small in stratum disturbance.
