repeating the steps, heating and maintaining the other pipe die, wherein the second control assembly corresponding to the pipe die does not stop working in the maintenance process until all the pipe dies are maintained;
opening a first control assembly and a third control assembly at the same time, keeping other control assemblies in a closed state so as to enable maintenance media to be gathered into a first main pipe and a second main pipe and simultaneously maintain the concrete pipe pile in the pipe die, closing the first control assembly and the third control assembly corresponding to the pipe die when the pressure and the temperature in the pipe die reach specified values, opening the third control assembly or the fourth control assembly corresponding to the pipe die, and enabling the pipe die to maintain a constant temperature and constant pressure state through the second control assembly or the fourth control assembly;
repeating the steps, heating and maintaining the other pipe die, wherein the third control assembly or the fourth control assembly corresponding to the pipe die does not stop working in the maintenance process until all the pipe dies are maintained.
