The tunnel crossing underneath Zhongzhou Avenue in Zhenzhou is constructed by rectangular pipejacking machines. The tunnel has such features as superlarge crosssection, shallow cover and 4 smallspaced parallel tubes. In the paper, the technologies used to control the attitude of the pipejacking machine, including deviation rectification by articulation cylinders, muck releasing by twin screw conveyors, different control modes of the six cutterheads, deviation rectification by grouting, control of the pipejacking machine in the construction of the smallspaced tunnel tubes, are described in detail. In the end, good effect has been achieved. 
