Staged Achievements of “Research and Application of Prefabrication & Assembly

Technology of Subway Station” Passed Expert Review

On October 20, 2014, the staged achievements of “Research and Application of Prefabrication & Assembly Technology of Subway Station” of the research project led by our company passed the expert review in Changchun. Wang Hanjun, the General Manager of the company attended the meeting; Yang Xiuren, the Chief Engineer as well as the project director, gave a detailed report on the staged achievements; major research members, such as Huang Meiqun, Wang Chen, also attended the review meeting. Wang Suqing (the President) and Qi Jilu (the Deputy-Secretary General) of China Exploration & Design Association were present and gave guidance.

The review meeting was organized by China Association of Metros and hosted by Song Minhua, the Deputy-Secretary General. Seven famous domestic experts including Yang Xiumin (Academician), Ge Xiurun (Academician) and Zhang Mi (Professor) were invited. Participated experts all agreed that, the idea of constructing subway stations with prefabrication & assembly technology is great as well as the construction manner, as it fulfils the engineering needs and the industrial development policies regarding construction engineering; the recommended subway station prefabrication & assembly program is feasible, as it is comprehensive in research content, correct in technical route and makes great breakthroughs in key technologies regarding structure form selection, joint types, waterproof measures, construction installation and component manufacturing.

Four years of hardworking were taken to facilitate preliminary systematic research achievements of prefabrication & assembly technologies for subway stations.

Constructing subway stations by applying “Subway Station Prefabrication & Assembly Technology” is obviously superior. For the construction of standard underground subway stations, applying the new technology will reduce 4-6 months in construction period and allow construction in winter; reduce 75% fewer operators to ease labor shortage in construction market; save woods and steel respectively by 500 - 800m3 and 1100t as well as cut construction wastes by 80%. It will mitigate the bad influence from construction to urban environment by the application of Prefabrication & Assembly technology in the underground stations.

Domestic urban rail transit will still keep rapid development in next 15-20 years and the popularization and application of “Subway Station Prefabrication & Assembly Technology” will expect favorable technical economy and social benefit.
