UV liner for the trenchless repair of underground and municipal sewers pipelines
Method for preparation of UV CIPP process
Use a CCTV robot to thread a rope to pull the bottom membrane: (use a braided rope, do not replace the rope at will, otherwise, the material or membrane will rotate in the pipe) the connection buckle between the rope head and the bottom membrane should be firmly fastened, and another rope to pull the material should be placed on the upper end of the bottom membrane (if a winch is used, it is a steel wire rope).
Ensure that the material and rope are not mixed with the rotation of the bottom membrane during the membrane pulling process. For long-distance materials with large pipe diameters, soapy water can be added to the bottom film to reduce the friction when the material is dragged.
