When the limit component needs to be fixed with embedded parts, a preset groove is first opened on the top of the sedimentation tank body, and then the I-shaped embedded part is cast and fixed into the preset groove by concrete. Then, the limit bolt fixes the limit plate and the limit curved ring to the I-shaped embedded part with the cooperation of the internal thread cap. When the limit component needs to be fixed with expansion nails, first separate it from the internal thread cap by rotating the limit bolt. In this process, the limit plate is separated from the I-shaped embedded part, and then the expansion bolt fixed to the top of the sedimentation tank body is inserted into the limit hole opened on the top of the limit plate, and then the limit plate and the limit curved ring are fixed to the sedimentation tank body by nuts, which effectively improves the convenience of reconstruction of old equipment.
