Description
Technical Field
The utility model relates to a lining hose technical field specifically is a non-excavation of underground piping is restoreed and is used lining hose.
Background
In the past, the method of excavating is adopted for repairing the pipeline buried under the urban road for discharging rainwater and sewage on the road surface, the road surface needs to be excavated, labor and time are wasted, the traffic is affected, and particularly in the city, the construction method is increasingly difficult, and the pressure brought to the urban traffic is too large. With the improvement of science and technology, in recent years, a large amount of integral repair technologies such as hot water curing and the like are adopted for repair, so that a good effect is achieved, and the social approval is obtained. But also find many problems simultaneously, often find that the inside lining restores back new pipe wall and appears the fold, and the inside lining exists gap etc. between new pipe and the old pipe, and the pipeline has the longitudinal joint who runs through the pipeline, makes the administrator to the pipeline quality whether qualified produce very big doubts. This is a big concern in the conventional resin-lined hose manufacturing process. The traditional hose is manufactured according to the same pipe diameter and the same specification, the manufacturing method comprises the steps of transversely folding and sewing fiber cloth, wrapping a layer of fiber cloth attached with a waterproof film on the outer layer, folding and sewing the fiber cloth in the same way, sealing the sewing position, vacuumizing the fiber hose, impregnating resin, rolling and leveling, and finishing the manufacturing. However, the diameter of the pipeline is basically measured at two ends of the pipeline, and the corrosion and other problems occurring in the actual pipeline are not uniformly distributed, so that the diameters inside the pipeline are different, the hose manufactured by measuring the diameter according to the pipe orifice cannot well meet the design requirements of the whole pipeline, and the condition that wrinkles or the fit is not in place can occur in part of the pipeline is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is overcome current defect, a lining hose is used in non-excavation restoration of underground pipeline is provided, the toughness and the stretch-proofing ability of pipeline have been improved, play certain design effect, adapt to more complicated operational environment, good water proof effect has been played, compare in the light more of glass fiber cloth of water proof, can realize being connected with the old pipeline is stable, seamless connection has been realized, and can not receive the inconsistent limitation of pipeline diameter, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a non-excavation of underground pipeline is restoreed and is used inside lining hose, includes inside lining hose, the inside lining hose outside is equipped with the glass fiber layer, and the surface on glass fiber layer is equipped with the water-stop film, inside lining hose inboard one side is equipped with enhancement layer and inoxidizing coating, and the inboard coating of inoxidizing coating has hot melt type resin.
Furthermore, the glass fiber layer is a diamond-shaped glass fiber net, and the weaving density of the glass fiber layer is 56% -60%, so that the toughness of the lining pipeline can be improved, a certain shaping effect is achieved, and the lining pipeline is suitable for a more complex working environment.
Furthermore, the thickness of the waterproof film is not more than 0.1mm, so that a good waterproof effect is achieved, and the waterproof glass fiber cloth is lighter and lighter compared with waterproof glass fiber cloth.
Furthermore, the reinforcing layer is a polyester felt layer, the thickness of the reinforcing layer is not more than 5mm, and the toughness and the tensile resistance of the pipeline are further improved.
Further, the protective layer is made of polyethylene resin, and the thickness of the polyethylene resin is not more than 0.3 mm.
Furthermore, the melting point of the hot-melt resin is 45-55 ℃, the thickness of the hot-melt resin is not more than 0.3mm, stable connection with an old pipeline can be realized, seamless connection is realized, and the limitation of inconsistent pipeline diameters cannot be received.
Compared with the prior art, the beneficial effects of the utility model are that: this underground conduit is lining hose for non-excavation restoration has following advantage:
1. can improve the toughness of the lining pipeline, play a certain shaping role and adapt to more complex working environment. 2. The waterproof glass fiber cloth has a good waterproof effect and is lighter and lighter compared with waterproof glass fiber cloth.
3. Further improving the toughness and the stretch-proof capability of the pipeline.
4. Can realize the stable connection with old pipeline, realize seamless connection, and can not receive the inconsistent limitation of pipeline diameter.
