Special film to protect CIPP liner from damage during trenchless repair

It is suggested that there should be 10 persons for one team, including one for overall process control, one for main equipment operation, and two for the bottom manhole.

Everyone should be proficient in the assembly of light chains, binding, binding, and other processes. In addition, when dragging materials, there shall be one person at the bottom of the well, at least four at the beginning, and two at the end if there is a winch. If there is no winch, more manpower is required to pull materials.

From the completion of pretreatment to the completion of curing, the whole process can be controlled within about 6-8 hours if skilled.
