摘要：
A lining element for repairing a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material, wherein at least three flexible, expandable lining parts are connected to each other by at least three connections to form the lining element. Each lining part comprises a main pipe section and a branch pipe section, and side edges. The lining element is characterized in that the lining parts are connected to each other by connecting both side edges of the adjacent branch pipe sections and side edges of adjacent main pipe sections in a continuous fashion.
