Definitions
- the present invention relates to a method and a device for the renovation and renewal of non-accessible pipelines.
- the method can be used both for straight and curved pipelines, in practice bends remaining easily processable up to approximately 45 °.
- Laminates As a film for lining the pipelines, there are those which are waterproof and curable by UV light.
- a glass fiber fabric is preferably used as the carrier material and a polyester resin which contains a UV catalyst is used as the curable resin.
- Isophthalic acid ester resin is particularly suitable as the resin and benzoylbutyl ether as the UV catalyst.
- the quantity ratio of fiberglass resp. Glass fiber fabric to polyester resin ranges from 4: 1 to 1: 4.
- An inflatable, highly elastic, high-tensile and transparent material is suitable as the hose.
- Soft UV-resistant silicone, PA, PVA, PU, PE or PVC hoses with rubber-like elasticity and extreme expansion options have proven particularly suitable and very high strength values in tear and abrasion resistance, as they are offered on the market.
- the hose material can be cut to lengths from approx. 20 cm to 20 m and more and attached airtight at one end to the pulling head and the inlet head.
- FIG. 1 shows a partial cross section through an embodiment of a device according to the invention while it is being drawn into a pipeline.
- FIG. 3 A further embodiment according to the invention is shown in FIG. 3 during positioning in a pipeline (24).
- the pull cables (32), (51) and (40) serve this purpose.
- a traction cable (32) is fixed to the traction head (5) by means of a traction ring (33).
- the inlet head has a pull rope (40).
- the lamp unit (31) is fixed to the feed head (5) by means of the bolt (35) and the spacers (37) rest on the lamp unit (31) in order to facilitate positioning of the device in the pipeline (24).
- the transport film (8) drawn only on one side serves the same purpose.

Abstract
Afin de remettre en état ou de rénover des canalisations dans lesquelles un homme ne peut pas passer, on introduit un paquet de film, le cas échéant avec une tête de transport (1) et un film à transporter (8), dans une canalisation (24) de diamètre réduit compris entre 10 et 30 cm environ. Le film (19) durcissable par exposition à des rayonnements ultraviolets est pressé contre la paroi intérieure de la canalisation endommagée (24) par une surpression générée dans le tuyau gonflable (9), puis est durci en peu de temps par la source de rayonnements ultraviolets (18) qui peut le cas échéant se déplacer dans le paquet dans le sens longitudinal. La longueur du film dont est constitué un paquet peut varier entre 20 cm et 10 m environ, selon la longueur du tuyau gonflable utilisé (9) et du film (19) enroulé sur celui-ci. Ce procédé convient donc aussi bien pour réparer des dommages localisés que pour rénover des sections tout entières de canalisations de plus de 100 m de longueur.
