Description

technical field [0001] The present application relates to the field of augmented reality technology, in particular to a method, device, computer equipment and storage medium for evaluating nuclear power plant pipeline reconstruction. Background technique [0002] During the operation of nuclear power units, a circulating water filtration system is required. The function of the circulating water filtration system is to filter the seawater required for the operation of nuclear power units. It is an important cold source system for operating nuclear power units. The pipes of the circulating water filtration system were originally made of stainless steel. Due to the long-term corrosion of seawater, the pipes of this material are prone to aging and corrosion, which affects the safe and stable operation of the circulating water filtration system. Therefore, in order to ensure the stable operation of nuclear power units, It is necessary to replace the circulating water filtration s...

Problems solved by technology

However, the transformation of corrosion-resistant pipelines for circulating water filtration systems using traditional technologies has the following difficulties: First, the required corrosion-resistant pipelines are prefabricated and supplied as a whole. There may be interference with other pipelines or system equipment, resulting in the impossibility of implementing the renovation plan, and the renovation construction space of corrosion-resistant pipelines has risks such as falling and flooding, and the traditional method of on-site analysis and interference cannot be implemented; The construction needs to be completed within the specified overhaul period of the nuclear power plant, which has a limited construction period. However, the renovation plan of the corrosion-resistant pipeline involves a wide range and a large space. When the engineers visit the site in person, they cannot accurately evaluate the construction progress of the renovation plan at the construction site. If The construction progress of the corrosion-resistant pipeline reconstruction does not meet the project requirements or the progress is delayed, which will prolong the overhaul period of the nuclear power plant and directly cause economic losses of the nuclear power plant; As-built assessment and acceptance are carried out, but due to the large number of pipelines and complex space involved in the corrosion-resistant pipeline renovation plan, the traditional method of sampling inspection and acceptance by personnel at the completion site cannot cover all the reconstructed pipelines, and there may also be sites where inspections are missed, such as Unfinished renovations or construction quality problems will directly affect the safe and stable operation of nuclear power plants

[0004] Through the analysis of the above difficulties, it can be seen that the traditional method is used to evaluate the transformation of corrosion-resistant pipelines. Since accurate interference evaluation cannot be carried out before construction, the evaluation process during construction is easily affected by the subjective factors of engineers, and the evaluation of construction progress is not accurate. After construction, random inspection is used. Completion acceptance assessment in this way is susceptible to the subjective influence of engineering personnel, and there may be omissions in acceptance and inaccurate assessment
