Description
Technical field
The invention belongs to municipal works field, and in particular to a kind of no-dig technique integrally repair with the preparation method of liner hose and
Its device.
Background technology
In the past, method of the pipeline rehabilitation for being used for road surface rain sewage discharge using excavating is embedded in below urban road, need to be opened
Road breaking face, it is time-consuming, traffic is influenceed, especially in city, this construction method is increasingly difficult, is brought to urban transportation
Pressure it is too big.It is a large amount of in recent years to be repaired using integral repair technologies such as water cures with the lifting of science and technology, take
Effect well is obtained, the accreditation of society is obtained.But simultaneously it has also been found that many problems, are frequently found new pipe pipe after liner is repaired
There is fold in wall, and liner is newly managed has gap etc. and old pipe between, because pipeline has the longitudinal interface through pipeline, makes pipe
Whether reason person is qualified to pipeline quality to produce very big suspection.
This and traditional lining resin flexible pipe manufacture craft have much relations.It is by same caliber, system that traditional flexible pipe makes
One specification makes, and preparation method is by fiber cloth transverse direction doubling suture, in one layer of fiber of laminating impermeable layer of outer layer covers
Cloth, is sutured using same doubling, is finally sealed in suture, then fiber hose is vacuumized, impregnating resin,
Leveling is rolled, completes to make.But because pipe diameter measurement is substantially carried out in pipe ends, and occur in actual pipeline
Corrosion the problems such as be not equally distributed, cause the diameter inside pipeline to differ, by the mouth of pipe measurement diameter make
Flexible pipe be not well positioned to meet the design requirement of whole segment pipe, cause some areas fold occurs or occur laminating less than
The situation of position.
