<p>PURPOSE: To perform proper execution of lining in a pipe line without using a large scaled equipment by inserting a spacer from one end opening part of the pipe line after diametrically spreading a lining material inserted into the pipe line. CONSTITUTION: Since a lining material 1 is formed into almost a cylindrical shape having a space part, the lining material 1 can be drawn into a pipe line P. Here in the case of providing a communication cable or the like laid in the pipe line P, the communication cable, holding it in the lining material from the space part, is drawn into the pipe line P. After the lining material 1, spreading its diameter in the pipe line P, is restored to almost the cylindrical shape, a spacer 2 is inserted to a spacer inserting part. Then, the lining material 1 is further diametrically spread, to form a lining pipe in the pipe line P, so that execution of lining in the pipe line P can be performed. Since a bonding agent is injected into the space part of the lining material 1 formed with the lining pipe in the pipe line P, the lining pipe can be secured into the pipe line P, and also adhesion can be improved so as to prevent a fluid from infiltrating between the lining pipe and a pipe line internal wall.</p> |
