What technological innovations have been adopted in the South-to-North Water Transfer Project?

In the scientific and technological work of the South-to-North Water Transfer Project, a large number of scientific and technological achievements such as new products, new materials, new processes, new equipment and computer software have been made. Complete 13 special technical standards (such as: technical specification and quality standard for heightening concrete dam of Danjiangkou Water Control Project, technical specification for mechanized construction of channel concrete lining, quality evaluation and acceptance standard for mechanized construction of channel concrete lining, etc.). ), applied for and obtained dozens of domestic patents (such as: anti-cracking method of new and old concrete joint surface after heightening gravity dam, long slope vibration slip-form forming machine, electric drum concrete lining machine, electrochemical deposition method to repair concrete cracks, etc. ) and achieved some scientific research results. A number of scientific and technological research achievements have won national and provincial scientific and technological awards (for example, large-scale channel concrete mechanized lining forming technology and equipment won the second prize of national scientific and technological progress; The key technology and application research of low-lift pump selection won the second prize of Dayu Water Conservancy Science and Technology Award; The research and application of anti-cracking method of pumping concrete in Huai' an No.4 Station won the third prize of Dayu Water Conservancy Science and Technology of the Ministry of Water Resources; Pccp won the third prize of Dayu Water Conservancy Science and Technology Award of the Ministry of Water Resources for the experimental study of water conveyance resistance; The remote deployment and operation of the first phase of the central line project won the first prize of scientific and technological progress of the Ministry of Education).

In the face of engineering and technical challenges, effective measures should be taken: First, in the early stage of engineering construction, scientific and technological work plans should be formulated to carry out major key technical research. First, scientific and technological research such as Danjiangkou dam heightening, pccp pipeline manufacturing and installation, and large-flow water pump design and manufacture on the eastern line should be started. Second, actively unblock the channels of scientific and technological innovation, implement relevant funds, and closely combine scientific and technological innovation with engineering construction. For example, the mid-line uses the engineering cost to carry out expansive soil (rock) tests in Nanyang and Xinxiang, providing scientific data for engineering design and putting forward relevant measures for expansive soil treatment. The model test of 1: 1 was carried out in the middle line yellow river crossing project, and a large number of design and construction parameters were obtained, which solved the optimization and comparison of design scheme and construction technology. The third is to use the market to allocate various resources to provide support for engineering and technological innovation. Many scientific research topics are combined with the national science and technology planning, and a major research project of South-to-North Water Transfer Project has been jointly established with the Ministry of Science and Technology, and has been included in the national "Eleventh Five-Year" science and technology planning. Signed scientific and technological agreements with Tsinghua University, Wuhan University and Hohai University; Using social resources to form a technical committee; Establish close contact with China Academy of Water Sciences and China Academy of Engineering. Many topics are promoted through social cooperation and resource allocation. For example, Wuhan University, Wuhan Geo University, Tsinghua University, Peking University and other universities were invited to solve the pollution problem in the production of Dioscorea zingiberensis from several different technical routes, and achieved initial results. The fourth is to establish a scientific and technological exchange and achievement sharing mechanism. Scientific and technological achievements are regarded as a kind of public resources, which are shared by the achievement forming units and related experimental units, and are widely used in engineering to ensure the efficiency of the achievements. Fifth, actively carry out international scientific and technological exchanges through introduction, absorption and re-innovation. Improve the production level and work efficiency of domestic channel lining machine, the equipment price is 80% lower than that of imported equipment, and the self-weight is reduced by two thirds, which not only meets the domestic demand, but also can be exported to foreign markets such as Pakistan and Malaysia.
