PROBLEM TO BE SOLVED: To realize the independent manipulation of the flow rate control of a pressurized fluid to a pressing member and the pressurizing force control of the pressurized fluid. SOLUTION: This pressurized fluid generating device for pipe line lining technique is of such a construction that a pressing member 23 which presses a lining material 13 with which an uncured curable resin is impregnated or to which it is applied into a pipe line inner wall 10A, is arranged in the pipe line and a pressurized fluid E is supplied by connecting the pressing member 23 to a circulatory pipe line K1 made up of a circulating pump PM1 and a flow rate regulating valve V1, and thus the pressing member 23 is pressed against the pipe line inner wall 10A to cure the curable resin, so that the pipe line is lined from the inner face. In this case, the discharge side (d) of a pressurizing pump PM2 which supplies a fluid from a fluid supply source W by forced injection is connected to the circulatory pipe line K1. Consequently, the flow rate control of the pressurized fluid to the pressing member and the pressurizing force control of the pressurized fluid are performed independently from each other. |
