In the prior art, urban drainage pipe network is the indispensable important infrastructure of modern city, is passed through to city
Basic industry of the Ji development with of overall importance, guiding influence, is the backbone of water pollution control in urban areas and Urban Waterlogging, flood control,
It is the important symbol for weighing modern city level.Currently, the reparation of drainage pipeline is all to use to open in China most cities
Again the method for pipe laying after digging, with the progress of urbanization, City Buried Pipeline is intricate, and the load of urban road is increasingly
Seriously so that there are a large amount of technical problems during reparation for underground utilities.It is non-to open with the constantly improve of urban construction
Dig pipe laying, repair pipe and change Manifold technology with its do not influence after traffic, pipelaying rate is fast, efficient, and no environmental disruption does not influence people
The a series of advantage such as normal work, life increasingly favored by underground piping Industry regulatory bodies.No-dig technique pipeline
Recovery technique rises the update reparation for being mainly used for oil, feed channel in oil, Gas Industry first, is gradually applied to later
In the renewal and reform of water supply and sewerage pipeline, and promoted rapidly with the application of the novel tubes such as PE pipes.
U-shaped liner PE pipe recovery techniques are also commonly referred to as Internal Lining Method of combining closely, and principle is to compare old pipeline using outer diameter
Internal lining pipe is pressed into U-shaped and temporarily bundled so that the reduction of its diameter, passes through traction by the smaller internal lining pipe of internal diameter by texturing machine
Internal lining pipe is penetrated old pipeline by machine, is then utilized hydraulic pressure or gas (vapour) pressure to open it with logical soft ball and is restored to original straight
Diameter makes internal lining pipe rise and is attached on the inner wall of old pipeline, closely coordinates with old pipeline, and the antiseptic property for forming internal lining pipe is managed with former
One kind " tube-in-tube " composite construction that the mechanical performance in road is combined into one.It will be interior with logical soft ball being pressed using hydraulic pressure or gas (vapour)
During bushing pipe is opened and is restored to original diameter, in the prior art generally in internal lining pipe both ends welded seal plate, liner
It manages after fully opening, the welded seal plate at dismounting internal lining pipe both ends, after pipeline rehabilitation in use, due to there is Jie in pipe
Matter pressure, internal lining pipe are eventually tightly attached to former inside pipe wall.The technology because it have sanitation performance is good, flow section loss is small,
The advantages that deformation scope of application is big and can repair over long distances is widely used to the related pipe network repair such as plumbing, but
Internal lining pipe both ends are sealed using welded seal plate, it is complicated for operation to be not easy field conduct.
