The invention relates to a stirring and grouting all-in-one machine, in particular to a vertical stirring and grouting all-in-one machine. In the grouting industry, a stirring and grouting separation device is generally adopted, that is, a stirrer and a grouting pump need to be each connected with a power source, and are required to be connected through a pipeline, consequently, the stirring and grouting separation device is complex in operation, low in efficiency, and large in occupied area, and particularly in the pit with the narrow and small space, operation is quite inconvenient. According to the technical scheme, an auxiliary barrel body is arranged at the right end of a stirring barrel body, and a vertical thick liquid absorbing and draining device is perpendicularly arranged in the auxiliary barrel body which is connected with the barrel body, and the auxiliary barrel body is communicated with the barrel body. The vertical stirrer and the grouting pump are combined, and the stirring and grouting all-in-one machine is small in size, light and convenient to transport and move; the pipeline for connecting the stirrer and the grouting pump is removed, and operation time for connecting the stirrer and the grouting pump is saved; meanwhile, the occupied area of the machine is reduced, and for some construction sites with the narrow and small space, and particularly occasions such as a mine and a roadway, use convenience and high efficiency are especially obvious.
