摘要:
The invention relates to a method of relining a sewer pipe having an area in need of repair. The sewer pipe is accessed via an access bore having an upper end and a lower end, and an access point at the upper end, and connected to the sewer pipe at a bore-pipe junction at the lower end. The method comprises providing a liner for insert-ing inside the sewer pipe such that the sewer pipe is relined. The method further comprises providing a tube for inserting said liner into said sewer pipe, and everting the liner such that the liner is turned inside out and said inside surface constitutes a temporary outside surface, placing the everted liner inside the tube such that the tube includes the liner and constitutes a tube-liner assembly having a free end, and moving the tube-liner assembly into the access bore with the free end such that the free end of the tube-liner assembly extends into said sewer pipe, inverting the tube-liner assembly when the free end is at bore-pipe junction such that the liner is placed with the outside surface facing the sewer pipe and covering the area in need of repair.
