Background technology
Urban duct is one of important infrastructure for supporting social development and ensureing people's lives, and pipe-line maintenance conserves
It is the necessary means for ensureing its normal mechanism and function.Under normal conditions, the repair of pipeline mainly by trenchless rehabilitation and
Two kinds of repair modes of non-excavation rehabilitation carry out pipeline rehabilitation.Trenchless rehabilitation directly excavates pipeline, then treats pipe-repairing
Repaired, environmental problem and economic impact are bigger existing for the trenchless rehabilitation of pipeline, and be easy to cause remaining pipes
Security incident caused by destruction etc. is reliable.However, non-excavation rehabilitation for infrastructure it is low influence, the repair mode of low-maintenance by
Gradually attention.But many of the trenchless repairing method of existing pipeline device is all disposable, can not realize and repeatedly follow
Ring uses, and increases fund input in pipeline rehabilitation.
The content of the invention
The technical problems to be solved in the utility model is the defects of overcoming the prior art, there is provided pipeline non-excavation rehabilitation fills
Put.
Realizing the technical solution of above-mentioned purpose is：
A kind of pipeline non-excavation rehabilitation device, including support device and repair membrane, the support device are arranged to tubulose knot
Structure, the support device are internally provided with annular seal space, and the support device lateral ends are equipped with inflating port, the inflating port
Connected with the annular seal space, the inflating port is equipped with constant pressure valve, and wearing layer and waterproof are equipped with the outside of the support device
Layer, the waterproof layer are located at the inner side of the wearing layer, and the waterproof layer includes the first waterproof layer and the second waterproof layer, and described the
One waterproof layer and second waterproof layer are disposed as fold-type structure, and first waterproof layer and second waterproof layer
Fold setting direction is mutually perpendicular to, and the repair membrane is arranged on the outside of the wearing layer in support device.
Preferably, steel screen layer is equipped with the wearing layer, and the steel screen layer is located at the middle of the wearing layer.
Preferably, the support device is process using the flexible material of even resilient.
Preferably, the repair membrane is using the glass-fiber-fabric for being soaked with resin.
The beneficial effects of the utility model are：The structure design of the utility model is reasonable, using support device and repair membrane knot
Design is closed, can be used to repair the simultaneously breakage such as gap, hole and crack of sealing pipeline, extends the service life of pipeline, right
Construction or traffic will not will not be influenced, and saved time and work to infrastructure not into destruction when pipeline is repaired
Journey cost, while support device uses the structure design of inflatable contraction, the present apparatus is may be repeated utilization, reduces pipe
The cost of road reparation, good airproof performance, corrosion resistance are good.
Brief description of the drawings

Embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Please refer to Fig.1, Fig. 2, the pipeline non-excavation rehabilitation device of the utility model, including support device 1 and repair membrane 2,
The support device 1 is arranged to tubular structure, and the support device 1 is internally provided with annular seal space 3, outside the support device 1
Side one end is equipped with inflating port 4, and the inflating port 4 is connected with the annular seal space 3, and the inflating port 4 is equipped with constant pressure valve
5, the outside of support device 1 is equipped with wearing layer 6 and waterproof layer 7, and the waterproof layer 7 is located at the inner side of the wearing layer 6, described
Waterproof layer 7 includes the first waterproof layer 8 and the second waterproof layer 9, and first waterproof layer 8 and second waterproof layer 9 are disposed as
Fold-type structure, and the fold setting direction of first waterproof layer 8 and second waterproof layer 9 is mutually perpendicular to, the reparation
Film 2 is arranged on the outside of the wearing layer 6 in support device 1.
Steel screen layer 10 is equipped with the wearing layer 6, and the steel screen layer 10 is located at the middle of the wearing layer 6,
The support device 1 is process using the flexible material of even resilient, and the repair membrane 2 is using the glass-fiber-fabric for being soaked with resin.
Operation principle：The winding of repair membrane 2 is wrapped in the outside of support device 1 first, then the present apparatus is transported through lower well
To at damaged sewer tube wall, compressed air is filled with by inflating port 4 by annular seal space 3 by air pump, fills the support
Putting 1 can be unfolded in pipeline to be repaired, and treats pipe-repairing inner wall and formed and keep certain pressure, by observing constant pressure
It is 1.0Bar that valve 5, which makes pressure be maintained at pressure limit, and the repair membrane 2 for further making to be wrapped in support device 1 is close to breakage
Sewer tube wall at, gradually cure by repair membrane 2 after ten minutes, finally in support device 1 gas discharge after it is extensive
Nature is arrived again, is carried out sewer, and the reparation of sewer breakage is into non-leakage state.The utility model structure design is closed
Reason, design is combined using support device and repair membrane, can be used to repair and gap, hole and crack of sealing pipeline etc. are damaged
Place, extends the service life of pipeline, will not will not be influenced to apply to infrastructure not into destruction when being repaired to pipeline
Work or traffic, and time and project cost have been saved, while support device uses the structure design of inflatable contraction, makes the present apparatus
Utilization is may be repeated, reduces the cost of pipeline rehabilitation, good airproof performance, corrosion resistance is good.
Above example is only for illustration of the utility model, rather than the limitation to the utility model, related technical field
Technical staff, in the case where not departing from the spirit and scope of the utility model, various conversion or modification can also be made, because
This all equivalent technical solution should also belong to the category of the utility model, should be limited by each claim.
