In the construction of large-scale hydropower projects in Qinghai Province, prestressed anchoring technology has been widely developed and applied. Combined with engineering construction, multiple scientific and technological achievements have been made in the exploration of new technologies in prestressed anchoring, the development of new construction processes, and the introduction and manufacturing of various anchoring devices. The development and application of these technological achievements have accelerated the progress of the project, saved investment, and improved the scientific and technological content of water conservancy and hydropower projects. Many achievements have not only generated huge economic benefits in the construction and safe operation of Longyangxia, Lijiaxia hydropower stations and other projects in Qinghai Province, but also made positive contributions to enriching China's prestressed anchoring technology
