Embodiment Construction
[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0074] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0075] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are b...

The invention belongs to the technical field of nuclear power station pipeline transformation, and provides a method for transforming an upstream sewage pipeline of a sewage station of a nuclear powerstation. The upstream and the downstream of a specific pipeline are plugged through rubber air bags, and then sewage in the selected pipe section is discharged; the selected pipe section is subjectedto dredging and primary cleaning by using a high-pressure water jetting mode, and then manual cleaning and vacuum cleaning are carried out respectively to dredge and clean of the pipeline; an endoscopic television detection device with a high automation degree runs in the selected pipe section, is controlled to conduct real-time shooting and data transmission, and is used for detecting the damagesituation in the selected pipe section; a lining tube is pre-arranged in the cleaned selected pipe section for a specific damaged region, after the lining tube is inflated and expanded, the lining tube is attached and fixed to the inner wall of the original pipeline through ultraviolet light curing, and repairing and transformation of the original pipeline are achieved. The transformation methodcan solve the problems that existing sewage draining pipeline repairing is difficult and high in cost can be solved.
Description
technical field [0001] The invention belongs to the technical field of pipeline transformation of nuclear power plants, and in particular relates to a transformation method for upstream sewage pipelines of sewage stations of nuclear power plants. Background technique [0002] The sewage pipes inside the nuclear power plant are used to discharge domestic sewage and treated radioactive waste water. The chemical composition of these sewage or waste water is complex. During the sewage discharge process, it is easy to cause corrosion or damage to the sewage pipeline, especially the connection between the wall surface of the pipeline and the pipeline is most likely to be damaged or corroded; Rainwater, etc. are easy to enter the sewage system, causing great sewage pressure to the sewage system. On the other hand, damage to the sewage pipes will lead to the accumulation of sludge on the pipe wall, which will gradually block the sewage pipes, resulting in the sewage system being una...
