After the water pipe system reform, in order to do a good job in the management of the Yellow River project in the new period, the Yellow River Committee has studied and compiled new management standards such as Yellow River Dike, Yellow River Channel Regulation, Yellow River Sluice Project and Maintenance of Internal Information of the Yellow River Project, which have made detailed provisions on the management, protection and modernization of the Yellow River flood control project, and the management of the Yellow River project tends to be refined. At the same time, industry management departments at all levels have also formed a large number of internal maintenance data in practical work. How to manage these data well and serve the project management well? Now I'd like to talk about some points on this issue: First, we should pay attention to the order in the arrangement of office materials. Before sorting out the data, we should carefully study and understand the specific content and requirements of the Yellow River Engineering Maintenance Industry Data Management Standard (Trial). According to the standard requirements, engineering maintenance documents should be sorted according to the time after the project is established, the approval before asking for instructions, the text before attachments, the text before drawings and the contents of data archiving. In addition, the image data before, during and after the maintenance of the project can be compared, and the photos of the data should be accompanied by dates and detailed text descriptions, and they should be classified into CDs in chronological order. Two, the management and utilization of indoor maintenance information should be accurate, complete and rapid. Establish a dynamic maintenance information management system to collect, sort out and analyze all kinds of words, data, charts, audio-visual images and electronic files formed in the process of project management, and input them into the computer in a timely, complete and accurate manner, so as to make the preservation of office materials safer and find them more convenient and fast. Third, by participating in various training courses and other forms, we will comprehensively improve the professional quality of personnel. In practical work, limited by the quality of personnel, there are often problems such as irregular and incomplete maintenance information records and improper use of professional terms, which can not fully reflect the real process of maintenance work. It is necessary to participate in various training courses, organize centralized learning, comprehensively improve the quality of maintenance personnel and data reorganization business personnel, and lay a solid foundation for doing a good job in industry maintenance and data management. Four, adhere to scientific and technological innovation, improve the technical content and technical level of industry information collation. In daily work, we should adopt the way of "going out, please come in", actively absorb and introduce new technologies and methods, and constantly improve the management level of internal data.
