Abstract:
Study is made on the following key technologies for the design of a superlarge rectangular pipe jacking machine (10.12 m×7.27 m): 1) study and selection of excavation modes of rectangular crosssection tunnels; 2) study on the strength and rigidity of the superwide, rectangular and thin shell of the pipe jacking machine; 3) study on the integrated electrohydraulic proportional control of the thrust system of the pipe jacking machine; 4) study on the soil conditioning of the rectangular tunnel. The results of the studies on aforementioned technologies have been successfully applied on a superlarge rectangular pipe jacking machine, which will provide an economic, safe and rapid solution for the construction of rectangular tunnels in urban areas.
Key words: superlarge pipe jacking machine, tunneling across underneath Zhongzhou avenue, finite element analysis, excavation system, thin shell, soil conditioning
