At present, a concrete base with a prefabricated steel pile mounting hole is generally cast in advance, and the method needs to cast the concrete base in advance, so that more labor force is consumed, the labor intensity is high, more concrete materials are consumed, the energy consumption is high, the working time is long, and the production cost is high.
