がある。[Problems to be Solved by the Invention] However, if the above-mentioned material mixture or clay such as bentonite is directly added to water, it may cause lumps, and when lumps occur, stirring must be continued for a long time. You may have to take precautions, such as adding ingredients to the water in small amounts to keep them from coming out. Furthermore, when fibrous materials are used, there are drawbacks such as the fibers clumping together and clogging the rotary valve, making it impossible to automatically measure the material when preparing the soil stabilizing solution.
