(1. Xiamen Metro Construction Co., Ltd., Xiamen 361001; 2. College of Civil Engineering, Tongji University, Shanghai 200092;3. China Railway 14th Bureau Group Grand Shield Construction Engineering Co., Ltd., Nanjing 211800;)
Abstract Addressing the technical challenges in the assembly construction of prefabricated mid-partition walls with large slenderness ratios for the Shanghai Airport Link Line shield tunnel, this paper first elucidates the structural characteristics of the prefabricated mid-partition walls and proposes the development concept of intelligent assembly equipment for the prefabricated mid-partition walls. The detailed structures of the assembly equipment are thoroughly introduced. Subsequently, the paper analyzes the posture control of the mid-partition walls and proposes posture control indicators. Finally, the developed equipment is used for the assembly construction of the prefabricated walls,and the corresponding construction methods are summarized. The results indicate that the developed assembly equipment can realize functions such as grabbing, flipping, and fine-tuning of the mid-partition walls, meeting assembly requirements under extreme conditions with good construction results, providing a reference for future similar projects.
