Description
Technical Field
The utility model relates to a municipal administration pipeline restores technical field, in particular to an ultraviolet curing local restoration inside lining for municipal administration pipeline restoration.
Background
In municipal pipe network local repair, a local resin curing non-excavation repair process is generally adopted, and two modes are provided:
the first mode is that two-component resin is mixed according to a certain proportion, the two-component resin is manually soaked and smeared on glass fiber fabric on a repair site, then the glass fiber fabric is coated on a repair air bag and sent to a position to be repaired in a damaged pipeline, the air bag is inflated to enable a repair material to be tightly attached to the pipeline, after a period of curing (the time is generally 2 hours), the air bag is deflated and pulled out, and the local repair of the pipeline is completed.
The second is a light-cured local repair process, which is to manually coat, soak and paint light-cured resin on a glass fiber fabric on a repair site, then coat the glass fiber fabric on a transparent repair air bag and send the transparent repair air bag to a position to be repaired in a damaged pipeline, an ultraviolet lamp is arranged in the air bag, after the ultraviolet lamp is turned on, the light-cured repair material is cured for a period of time (generally 15 minutes), and the air bag is pulled out after deflation to finish the local repair of the pipeline.
Both of these methods are to apply resin to the glass fibers at the job site. Volatile gas in the resin pollutes the surrounding environment and influences the health of workers, the resin is not soaked uniformly, the proportion of the resin and the glass fiber is not easy to master, bubbles are not easy to remove, the repair quality is not reliable, the resin is in direct contact with a wet pipeline, the service life is influenced, and water cannot be stopped. In addition, the first mode cannot be used when the ambient temperature is more than 35 ℃ and less than 5 ℃, and the time for preparing the material to the pipeline repairing position is 15 minutes, which is not easy to master. The second method has the first disadvantage that the light-cured resin is coated on the glass fiber fabric and needs to be kept away from sunlight, otherwise the resin is easy to cure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to reach the purpose of providing an inside lining is restoreed to ultraviolet curing part, this inside lining simple structure, intensity height, restoration quality are reliable, carry construction convenience, restore advantages such as back leakproofness is good, durability, have extensive suitability.
The technical scheme of the utility model as follows: the ultraviolet light cured local repair lining is a seamless ring, the ring is composed of a transparent inner film layer, a glass fiber reinforced and light cured resin layer and an ultraviolet-proof outer film layer from inside to outside in sequence, and two ends of the repair lining are respectively stuck between the transparent inner film layer and the ultraviolet-proof outer film layer by transparent sealing tapes to seal the transparent inner film layer and the ultraviolet-proof outer film layer.
As one preferable technical scheme, the repair lining is also provided with a water stop ring sleeve outside the ultraviolet-proof outer membrane.
As one preferable technical scheme, the water stop rings are symmetrically sleeved on the repair lining and are positioned at positions with certain distances inwards at two ends of the repair lining.
As a preferable technical scheme, the water stop ring sleeve is fixed on the surface of the ultraviolet-proof outer film layer in an adhesive mode.
As one preferable technical scheme, the water stopping ring is sleeved by an O-shaped sealing ring, a square sealing ring or other sealing materials.
Compared with the prior art, the beneficial effects of the utility model are that: this material is soft before the non-solidification, can fold and put in opaque wrapping bag, conveniently carries, during the construction, only needs to open the wrapping bag, restores the inside lining with photocuring, overlaps on photocuring restores the gasbag, sends into and treats the restoration pipeline position, opens the ultraviolet lamp and can solidify fast, and restoration quality is reliable, has improved work efficiency, and no toxic substance safety ring protects, and stagnant water snare makes the pipeline after the restoration not leak, and the leakproofness is better.
