PURPOSE: An adhesion method for a bending part of a pipeline of a soft tube at no-digging tube repair work by cured in place pipes is provided to prevent the formation of wrinkles and gaps, to make an inflow of water flow and to improve durability by reinforcing structural strength of a pipeline to be repaired. CONSTITUTION: The adhesion method for a bending part of a pipeline of a soft tube at no-digging tube repair work by cured in place pipes comprises the steps of: interposing and expanding a soft tube(2) in an outworn tube(1); interposing a rubber tube(3) in the soft tube(2), then locating in a bending part of the outworn tube(1); expanding the rubber tube(3) by adding water pressure or air pressure through a water pressure, air pressure injection hose(4) connected to the rubber tube(3); and adhering the soft tube(2) closely to an inner wall of the outworn tube(1), then hardening.
