Zusammenfassung:A pipe lining method is provided to cool hardened pipe lining material by cooling heated water and steam used to harden pipe lining material. A pipe lining method includes the steps of: expanding a pipe lining material(3) inserted in a pipe line(1) to adhere the pipe lining material to the inner wall of a pipe; injecting heated water(18) or steam(20a) to the pipe lining material adhered to the inner wall of the pipe to thermosetting resins impregnated in the pipe lining material; discharging heated water or steam flowing on the bottom of the pipe lining material to the outside by using a pump(42) and cooling the discharged heated water with a cooling device(43); and injecting cooling water to the pipe lining material. Heated water and steam flow through a first hose, and cooling water flows through a second hose.
