Abstract
The utility model relates to a renewed water transport pipe with an inner lining of nonwoven composite fiber film. Nontoxic and nonirritant nonwoven fiber cloth is used as a framework 1; one surface of the framework is melted with one layer of polyethylene film 2 in a hot mode to form a composite film 3; the composite film is made into a cylinder 5 which has the same inner diameter with a pipe 4 to be repaired; the outer layer of the cylinder is stuck on the inner wall of the pipe to be repaired. The utility model can repair and renew an old metal pipe still having definite strength and provided with leak holes; a road surface does not need to be dug, onlya pit which can expose end pots of the old pipe is respectively dug at the road surface at both ends of the old pipe, and repair and renewal can be carried out. The utility model has the advantages of high speed, low cost and good anticorrosive effect.
Description
The online conduit pipe that the utility model is mainly used in outmoded corrosion leakage renovates.
Owing under the long-term effects such as physics, chemistry, electrochemistry, microorganism, produced corrosion thing, sediments on the aqueduct inwall, this certainly will influence water supply quality in aqueduct.Simultaneously, corrosion causes pipe leakage also the reliability that supplies water to be caused influence, and has caused waste.For the more serious old metal tube of burn into perforation, can only adopt the way that more renews pipe now.This way is not only long in time limit, cost is high, and some is embedded in the aqueduct under important highway section and the building, the just difficult more and increase cost of renewal.
The purpose of this utility model is a kind of renewal conduit pipe with the non-woven composite cellulosic membrane of liner of development, this measure is repaired the old metal tube that certain intensity is still arranged, can effectively prolong the working life of pipeline, save the pipeline update cost significantly, shorten the revision cycle, strengthen antiseptic property, improve water supply quality.
The utility model is a skeleton 1 with nontoxic, non-irritating non woven fibre cloth, a hot melt at skeleton 1 has layer of polyethylene film 2, become composite membrane 3, composite membrane 3 is made and is repaiied the identical cylinder 5 of pipeline 4 internal diameters, the internal layer of cylinder 5 is polyethylene films 2, the skin of cylinder 5 is non woven fibre cloth skeletons 1, and the skin of cylinder 5 cements on the inwall of being repaiied pipeline 4.
The utility model is for still having certain intensity and having the old metal tube of weepage holes can carry out restoration updating, and it need not excavate the road surface, and only respectively digging a hole of exposing old tube opening at the two ends of old pipeline just can carry out restoration updating.It has that reparation speed is fast, cost is low, favorable anti-corrosion effect, the advantage of water supply quality can effectively improved.
Fig. 1 is an overall structure schematic representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment one: present embodiment is to be skeleton 1 with nontoxic, non-irritating non woven fibre cloth, a hot melt at skeleton 1 has layer of polyethylene film 2, become composite membrane 3, composite membrane 3 is made and is repaiied the identical cylinder 5 of pipeline 4 internal diameters, the internal layer of cylinder 5 is polyethylene films 2, the skin of cylinder 5 is non woven fibre cloth skeletons 1, and the skin of cylinder 5 cements on the inwall of being repaiied pipeline 4.On when construction outer wall, be coated with equal glue, with 5 one sealings of cylinder and flatten, then the cylinder 5 that flattens put in the pipeline 4 that desire repairs cylinder 5, at the opening end of cylinder 5 with blower with cylinder 5 inflations, and cement on the inwall of pipeline 4.
Embodiment two: it is two-layer at least that present embodiment and embodiment's one difference is that composite membrane 3 is made, and repaiied the needs of pipeline 4 to adapt to different extent of corrosions.Other composition is identical with embodiment one with annexation.
Claims (2)
1, a kind of renewal conduit pipe with the non-woven composite cellulosic membrane of liner, it is characterized in that it is skeleton (1) with nontoxic, non-irritating non woven fibre cloth, a hot melt at skeleton (1) has layer of polyethylene film (2), become composite membrane (3), composite membrane (3) is made and is repaiied the identical cylinder (5) of pipeline (4) internal diameter, the internal layer of cylinder (5) is polyethylene film (2), the skin of cylinder (5) is a non woven fibre cloth skeleton (1), and the skin of cylinder (5) cements on the inwall of being repaiied pipeline (4).
