Description

Technical Field

[0001] The utility model relates to the field of repair hoses, in particular to a glass fiber reinforced ultraviolet light curing pipeline repair hose. Background Art

[0002] In the field of pipeline repair, glass fiber reinforced UV-curing pipeline repair hose has been widely used as an advanced repair material. Its characteristics are that it uses glass fiber for reinforcement and combines UV curing technology to quickly and effectively repair damaged pipelines in a short time. However, despite the many advantages of this repair hose, there are still some problems that cannot be ignored in the actual application process.

[0003] Specifically, during the installation and repair process of the repair hose, since it needs to be dragged into the pipe to be repaired, or in some cases it needs to be laid on the ground for operation, it is inevitable that it will rub against the ground or other objects. This friction, especially when encountering sharp objects, can easily cause the outer material of the repair hose to be scratched or damaged.

[0004] Once the outer layer of the repair hose is scratched, the key repair materials such as the glass fiber layer and curing resin inside will be exposed, which will not only seriously affect the waterproof and pressure resistance of the repair hose, but may also greatly reduce the repair effect and even require re-repair. In addition, the damage of the outer layer material may also increase the risk of the repair hose during installation and use, posing a potential threat to the safety of construction workers and users. For this reason, we propose a glass fiber reinforced UV-curing pipe repair hose. Utility Model Content

[0035] Furthermore, the outer surface of the fireproof film 6 is fixedly adhered to the inner wall of the outer film 7, and the inner wall of the fireproof film 6 is fixedly adhered with the tensile film 5, and the fireproof film 6 is made of polyamide fiber, and the surface of the fireproof film 6 is coated with PVC resin.

[0036] Furthermore, the inner wall of the tensile film 5 is fixedly adhered to the outer surface of the glass fiber film 4, and the tensile film 5 is cross-woven by metal wires and polyester fiber wires to form the required membrane structure.

[0037] Furthermore, the glass fiber membrane 4 is woven from bundles of glass fibers, and the glass fiber membrane 4 is woven in a gingham pattern, and the ratio of the transverse and longitudinal fibers of the woven gingham is about 2:1.

[0039] Working principle: When the repair hose is needed for pipeline repair, first drag the repair hose from the inspection well into the pipeline to be repaired. The pulling rope 1 is used to control the dragging speed and position of the hose to ensure that the hose can accurately reach the repair position. The wear resistance of the nylon fiber braided material of the protective film 8 and the friction-resistant rubber material properties of the wear-resistant rod 9 effectively prevent the hose from being damaged by ground friction during installation. Then, high-pressure air or other appropriate methods are used to expand the hose and make it fit tightly against the inner wall of the pipeline to be repaired. The hose uses the fireproof film 6 and the tensile film 5 to enhance the stability and durability of the hose during the expansion process. The waterproof film 3 is used to ensure that when the inner film 2 ruptures for some reason, no damage will occur. The water leakage phenomenon is prevented, which ensures the durability of the repair effect. At the same time, the tensile film 5 is cross-woven by metal wire and polyester fiber, which significantly enhances the tensile performance of the glass fiber membrane 4, so that the hose is not easily damaged during transportation under tension during installation. Then, after the hose is close to the inner wall of the pipe, the hose is irradiated with LED light curing equipment or other ultraviolet light sources. Under the irradiation of ultraviolet light, the resin material in the hose begins to cure and is tightly combined with the glass fiber membrane 4 to form an inner lining tube with a certain strength. As the resin material is completely cured, the hose is tightly combined with the inner wall of the pipe to form a complete, sealed and durable repair layer. The pulling rope 1 and other auxiliary tools are then removed, and the repair work is completed.
