RENOVATION DRAIN SYSTEM FOR REPAIRING CONCRETE DRAIN
Renovation drains and liner members are used for repairing sewer drains, storm drains, and other drains made of concrete. The invention concerns a renovation drain system comprising a liner member (100) for repairing a concrete drain. The liner member (100) includes liner (101) to be prepared with impregnating compound, a first branch (102) intended to extend into a concrete drain inlet pipe, and a second branch (103) intended to extend into an outlet pipe. The liner (101) has a liner hole (104) between the first branch (102) and the second branch (103). The liner member (100) further comprises a bushing (105) retaining its shape, and a collar (106) for attaching the bushing to the liner (101) such that the bushing operates as a third branch of a liner member (100). The liner hole (104) is located at the bushing (105) and forms with the bushing an inlet (107) from a renovation drain (202) into the liner member (100), and the collar (106) adheres around the liner hole (104) to the liner member.
