Scientific and technological achievements

With the spirit of “concentrated in innovation, professionalized in service”, our company continuously builds up enterprise brand in two major business fields: bridge modification and soft soil foundation treatment. The Technology Center was founded in 2007. In 2009, the company became a membership unit of academic journals like “Highways” and “Bridges”. It became the deputy agent unit of Bridge Management and Maintenance Branch of China Highway Institute in 2010 and a member of“National Engineering Laboratory of Bridge Safety Technology” in 2013. In 2014, it became the Bridge Modification and Reinforcement & Soft Soil Foundation Treatment Branch Center of the Technology Center of CCCC 2nd Harbor Engineering Company. In the same year, our company became a standing director member of the Third Council of China Dredging Association. In 2015, our company organized the Utilization of Mud Resources Committee of China Dredging Association. For years, our company has been carrying out long term cooperation with academy, institute, public institution and incorporation such as China Academy Of Sciences, Highway Science Institute of Ministry of Transport, HUST, Southeast University, Wuhan University of Technology, Chang'an University, Chongqing Jiaotong University, Changsha University of Science and Technology, etc. Bases on our and industrial bridge modification & extension projects and soft soil foundation treatment projects, combining with “construct, study and research”, we engaged in technology R&D&I (research, develop and innovation), mainly for related equipment, working methods, materials, etc. Our company has hosted and participated in many technical researches. It has won both project approvals and sponsors from many authorities such as Science and Technology Department of Hubei Province, CCCC, and so on.In 2020, the S&T Association of the company was established. In the same year, we had been given the title of Automated Operation Technology Transportation Industry Research and Development Center, Wuhan Model Workers’ Innovation Studio, CCCC Craftsman Talent Innovation Studio, had been approved to establish the National Engineering Design Master Studio.

In recent years, our company has made great breakthrough in the field of technology R&D&I, have obtained: 156 national patents 42 patent for invention; 60 construction methods, among which there is one construction method at national level, and 31 at ministerial and provincial-level; edited and co-edited 3 books of monographs and manuals, 33 sets of industrial standards, which 1 set of industrial standard is leading edited by us; won 71 S&T Progress Awards, among which are 5 first prizes at provincial and ministerial level, 15 second prizes, and 11 third prizes; and also won 4 CCCC’s Demonstration Projects on Energy Conservation, Environmental Protection and Circular Economy.
