Abstract
The utility model relates to a renewed water transport pipe with an inner lining modified polyvinyl layer. The utility model is composed of a modified polyvinyl inner lining pipe 1 and an old metal pipe 2, wherein, the modified polyvinyl inner lining pipe 1 is hot melted and solidified on the inner wall of the old metal pipe 2. The utility model can repair and renew the old metal pipe still having definite strength and provided with corrosion leak holes; a road surface does not need to be dug, repair and renewal can be carried out by that the road surfaces of both ends of the old pipe are respectively dug with a pit which can expose end pots of the old pipe. The utility model has the advantages of high speed, low cost, good anticorrosive effect and capability of improving the water quality of water supply.
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 liner modified poly ethylene layer 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, improve antiseptic property, improve water supply quality.
The utility model is made up of modified poly ethylene internal lining pipe 1, old metal tube 2, and polyethylene liner pipe 1 hot melt is solidificated on the inwall of old metal tube 2.
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: present embodiment is made up of modified poly ethylene internal lining pipe 1, old metal tube 2, and modified poly ethylene internal lining pipe 1 hot melt is solidificated on the inwall of old metal tube 2.When constructing at the scene, end sealing and flattening with modified poly ethylene internal lining pipe 1, polyethylene liner pipe 1 is reached in the old metal tube 2 then, with blower internal lining pipe 1 is blown circle again, at last in the heating of the inside of internal lining pipe 1, make it reach the melting state, and then make internal lining pipe 1 blow on the inwall of old metal tube 2.
Claims (1)
1, a kind of renewal conduit pipe with liner modified poly ethylene layer is characterized in that it is made up of modified poly ethylene internal lining pipe (1), old metal tube (2), and modified poly ethylene internal lining pipe (1) hot melt is solidificated on the inwall of old metal tube (2).
