Relying on the strategic cooperation platform of Changchun Machinery Research Institute of the Ministry of Water Resources, the company has in-depth cooperation with the following authoritative scientific research institutions:
The company has established a trinity R&D system of "Basic Material R&D - Intelligent Equipment Manufacturing - Digital Operation and Maintenance Services" and built an integrated innovation ecosystem of "Industry-Academia-Research-Application".
The company's technological innovation achievements have been transformed into 3 industry standards, and it has led the compilation of the following specifications:
Adhering to the corporate mission of "Intelligently Manufacturing Water Conservancy Equipment, Benefiting Ecological Well-being", the company is based on the construction of a BIM+GIS-based smart water conservancy equipment cloud platform. It continuously deepens the integrated innovation of digital twin, artificial intelligence and water conservancy equipment, and promotes the upgrading of the modern water conservancy infrastructure system towards intelligence and ecology.
The company's core team has been engaged in nuclear industry rubber equipment for more than 20 years, with independent corporate technologies and an R&D center. Relying on the strategic technical cooperation with Changchun Machinery Research Institute of the Ministry of Water Resources, it has gathered expert resources from Xi'an Jiaotong University, Ocean University of China, Hohai University and other institutions.
Mainly engaged in the research, development, design and quality evaluation of water conservancy-specific construction machinery, water conservancy dredging technology, pneumatic shield gates, and new-type water conservancy gates.
As the academic leader of the "Introduction of High-Head Ecological Check Gates" project under the "948 Program" of the Ministry of Water Resources, he organized an expert team to realize the work of "introduction, digestion and absorption" of imported pneumatic shield gates. This promoted the localization of pneumatic shield gates, making their technical indicators such as air tightness, safety and structural stability far exceed those of imported products.
