Abstract

Sammendrag: Segment som er koblet til ytterligere segmenter for å utgjøre et segment (3) for rehabilitering av en eksisterende rørledning (4). Segmentet (1) omfatter ei indre plate (101) som avgrenser den indre omkretsoverflata til segmentet for rehabiliterings-rørledningen og har en åpning (101a) for utføring av arbeid med gjensidig kobling av segmenter (1) i omkretsretningen til segmentet for rehabiliterings-rørledningen (3), og et lokk (14) som er tilpasset i åpningen til den indre plata. For å feste lokket til den indre plata, er lokket (14) anordnet med et fremspring (14a) og et inngripende element (15) som er bevegelig mellom ikkeinngrepsposisjon og inngrepsposisjon. Lokket (14) er tilpasset inn i åpningen (101a) med fremspringet (14a) i inngrep med den indre plata (101) på en av sidekantene til åpningen, det inngripende elementet (15) beveges så til inngrepsposisjon hvor det kommer i inngrep med den indre plata (101) på dens ene sidekant, og fester dermed lokket til den indre plata for å tette åpningen (101a).Summary: Segments connected to additional segments to constitute a segment (3) for rehabilitation of an existing pipeline (4). The segment (1) comprises an inner plate (101) defining the inner peripheral surface of the rehabilitation pipeline segment and having an aperture (101a) for performing interconnecting segments (1) in the circumferential direction of the rehabilitation pipeline segment (1). 3), and a lid (14) fitted in the opening of the inner plate. To attach the lid to the inner plate, the lid (14) is provided with a projection (14a) and an engaging element (15) movable between non-engaging position and engaging position. The lid (14) is fitted into the opening (101a) with the projection (14a) engaging the inner plate (101) on one of the side edges of the opening, the engaging element (15) then being moved to the engaging position where it engages the inner plate (101) on its one side edge, thereby attaching the lid to the inner plate to seal the opening (101a).
