Guide: the National 863 large diameter mud water shield dissipative absorption and design project undertaken by the tunnel Technology Center - Amp for the South-to-North Water Transfer across the Yellow River project; Oslash; The 9040mm slurry air balance shield design project passed the National 863

the national "863" large diameter slurry shield digestion, absorption and design project undertaken by the tunnel joint stock technology center - the 9040mm slurry air balance shield design project for the South-to-North Water Transfer across the Yellow River project, was accepted by the national "863" expert group organized by the Ministry of science and technology on march16,2007 in Xinxiang, Henan Province, The expert group agreed that the project has developed from imitation skills to digital skills. Based on the introduction, digestion and absorption of foreign large-diameter slurry balanced shield tunneling machine technology, the project has adopted advanced system integration technology to study and design a 9.04m slurry air balanced shield. Its main technical indicators have reached the international advanced level, providing a technical foundation for the manufacture of large-diameter shield in China and improving the technical level of shield in China

since the 20 frequently used loads were 5N and 10N. Since the project was launched at the end of 2005, the project team has organized the implementation according to the annual plan and annual assessment indicators of the project. President zhouwenbo of the company has personally grasped the progress of the project, the deputy chief engineer in charge of shield design of the company has personally grasped the technical implementation of the project, and all technicians in the machinery room of the technology center have participated in the design of the project. Due to the attention of the company's leaders, a research group composed of elite and strong generals in shield design is organized and implemented according to the annual plan and annual assessment indicators. Therefore, the project can be implemented on time, according to the quality and according to the annual assessment plan, and the whole content of the project can be completed on time and according to the quality

The

9040mm slurry air balance shield design project passed the acceptance of the national "863" expert group. The machinery room won honors for the company and the technical center, and laid a good foundation for the company to undertake the "863" project again
