A port inserting and connecting wall making machine comprises a concave arc drilling machine and a convex arc drilling machine. A plurality of cemented soil concave arc piles at the interval of one convex arc pile are manufactured; and when the strength of the cemented soil of the concave arc piles on the two sides reaches a certain degree, one cemented soil convex arc pile is manufactured within the interval between every two concave arc piles through the convex arc drilling machine according to a work manner of the above convex arc drilling machine, and in this way, a pile wall formed in the manner that the multiple cemented soil concave arc piles and the cemented soil convex arc pile between every two concave arc piles are subjected to mutual port inserting and connecting is formed and used for soil retaining and leakage prevention of a building foundation.
