In the 1970s, rectangular pipe jacking was first developed and successfully applied in the Tokyo underground passage. After several years of research and development, rectangular pipe jacking technology with a width of more than 6 meters and a height of more than 3 meters has become popular in Asia. At present, the rectangular pipe jack is suitable for a series of soil layers and weak rock layers, and adopts the earth pressure balance excavation method. Combined with the above characteristics, the use of the rectangle pipe jacking machine is also becoming more and more extensive in life.
