The application of RCC dam technology in major hydropower projects is a national key project of the Seventh Five-Year Plan, numbered 17-2-6. By the first unit in charge of our hospital, hydropower Seventh Engineering Bureau as the second responsible unit, shared the research task. RCC mix and its performance research and construction technology and equipment research is an important part of the project, Water Conservancy and Hydropower Planning and Design Institute in June 1990 on the 13th. Copper Street in the hydropower project site presided over the appraisal of scientific research, attended by the institutions of higher learning, research, design, construction and other experts, scholars, engineers and technicians, a total of more than 50 people. The review concluded that the technical route of the research was correct, the theoretical analysis was reliable, the contents were comprehensive, the system was rich in experimental data, the data were credible, the main conclusion was correct, and the research task was fulfilled according to the requirements of the contract. The research results ranked the leading domestic level, With RCC performance test, test scale, scope and achievements of the leading international level; RCC craft, the research results of the machine has a systematic and practical, in the construction of copper street sub-project to create a 7000m ~ 2 Roller compacted concrete surface construction record, reached the international advanced level.
