Sanhe has strong technology and rich experience. Our R&D is composed of over 90 researchers, including 2 professor-level senior engineers, 1 registered structural engineer (I grade) 36 senior engineers, 48 engineers. 90% of them have an intermediate or higher professional title.
Our main technology and production experts were responsible for and executed the concrete batching plant of hundreds of national key projects, such as Three Gorges, Wanjiazhai Water Transfer Project, Longtan Hydroelectric Project, Xiaowan Hydropower Sation, Jinping Project, Xiluodu Hydropower Project, Xiangjiaba Projects. One of them has presided over the 4x4.5m 3 ultra-large concrete batching plant of Three Gorges Project during the 9th Five-Year Plan, 2x6m3 super-large concrete batching plant of Longtan Hydroelectric Project, which is the National Key Technologies R&D Program during the 10th Five-Year Plan. Another 12 experts have also participated in the above two projects and in the development of the 4x3m3 large concrete batching plant development of the Three Gorges Project, which is the National Key Technologies R&D Program during the 7th Five-Year Plan.
Over the years, 8 researchers have won the first prize of Water Resources Science and Technology Progress Award. 9 of them won the second prize of Henan Science and Technology Progress Award, and 2 of them won the first prize of Dayu Water Resources Science and Technology Progress Award. San he gained a series of innovation results in the field of construction machinery.
Sanhe focuses on research and development and innovation. Several models are originated by ourselves. We have now gained more than 100 invention patents and utility model patents.
1 of our experts is the main drafter the existing national standard of concrete batching plant, 2 of them are the main drafters of for the industrial standard of concrete mixing plant in water conservancy industry, 2 of them are main drafters of construction regulations of ready-mixed mortar in Henan. In addition, we are the participant unit of compilation of Henan Construction Standards (DBJ41T 078-2015): ready-mixed mortar production and application of technical regulations.
We successfully developed the largest compulsory concrete batching plant (2x7 m3) in the world and the largest gravity type concrete batching plant (4x4.8 m3) in China. Our R&D team developed a variety of models of concrete batching plant, and completed more than 75% of high strength, large volume concrete pouring tasks for hundreds of domestic hydropower stations, including low temperature concrete, preheated concrete, normal concrete, roller compacted concrete, etc.
Our company is honored as “New High-Tech Enterprise in Henan Province”, “Key Member Enterprise for the National Project of Bulk Cement Promotion”. Our research center also win us the titles of “Municipal Enterprise Technology Center of Zhengzhou City”, “Provincial Enterprise Technology Center of Henan Province”, “Municipal Concrete and Dry Mortar Equipment Engineering Technology Research Center of Zhengzhou City”, “Provincial Concrete and Dry Mortar Equipment Engineering Technology Research Center of Henan Province”.
Over the years, we always insist on scientific and technological innovation. We continue to sum up our experience and explore new technologies to keen on equipment innovation. As a leader of concrete mixing equipment and other mixing equipment industry, we have made tremendous contributions for China's hydropower, high-speed rail and urban construction industries.
