The invention provides a prefabricated assembly type steel reinforced concrete independent foundation under a column. The independent foundation is sequentially provided with a self-setting plain concrete cushion layer, a cement mortar leveling layer, a bottom-layer steel reinforced concrete prefabricated block, a middle-layer common concrete prefabricated block, an upper-layer common concrete prefabricated block and a prefabricated steel base plate from bottom to top; and a prefabricated steel column is perpendicularly welded on the prefabricated steel base plate, and the self-setting plain concrete cushion layer, the cement mortar leveling layer, the bottom-layer steel reinforced concrete prefabricated block, the middle-layer common concrete prefabricated block, the upper-layer common concrete prefabricated block and the prefabricated steel base plate are fixed into a whole through anchor bolts and nuts. According to the adopted assembly type steel reinforced concrete independent foundation under a column, block bodies are prefabricated in a factory, the weight is light, the precision is high, and the manufacturing quality is easy to guarantee; the block bodies are meshed with one another in a layered mode, the bolts are adopted for connection, so that disassembling and assembling are convenient, and the repeated utilization rate is high; and the block bodies can be manuallycarried, large construction machinery is not needed, so that flexibility and convenience are achieved.
