[0027] Working principle: The reinforcement process is as follows: S1: First, the external column inserting machine moves the reinforcement column group 1 through the upper lifting port 125 and vertically inserts it into the silt foundation, and the reinforcement column group 1 is distributed in the transverse and longitudinal arrangement with one column inserted every 2m.
