Introduction to the Company and Its Core Technical Team

I. Company Overview

The company is a high-tech industrial equipment manufacturing enterprise located in Huangdao District, Qingdao. Its core team has been engaged in nuclear industry rubber equipment for more than 20 years and owns 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, the company has gathered expert resources from Xi'an Jiaotong University, Ocean University of China, Hohai University and other institutions, and possesses profound technical accumulation and R&D capabilities in related fields.

II. Profile of the Chief Technical Engineer

The Chief Technical Engineer is 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.

Over years of practice, he has achieved fruitful results, including:

• Participated in and completed more than 20 scientific research, design, testing and supervision projects, such as the R&D of shield rubber dams, the R&D of WBC-150 excavation and pumping vessels, the R&D of CY100 salt harvesters, the development of tidal flat soft foundation solidifiers, and the 2017 dam safety appraisal in Jilin Province;
• Presided over more than 10 scientific research projects;
• Published more than 10 papers;
• Held more than 10 patents;
• Compiled 4 standards;
• Published 1 monograph;
• Won 1 First Prize and 1 Third Prize of Kunlun Science and Technology Award from the Comprehensive Service Bureau of the Ministry of Water Resources, etc.

As the academic leader of the "Introduction of High-Head Ecological Check Gates (High-Head Pneumatic Shield 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 has 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.
