Abstract

The development history and current research status of rectangular pipe jacking technology are investigated. The current primary application scenarios for the rectangular pipe jacking technology are presented, and the theoretical investigation of rectangular pipe jacking is reviewed and analyzed in terms of jacking force prediction, grouting effect of drag reduction, back soil evolution mechanism and control countermeasures, jacking strata response pattern and settlement calculation, and working face stability evaluation. Furthermore, the advancements and classifications of rectangular pipe jacking machines are presented based on their structure form and cutting mode. Finally, the current technical challenges of rectangular pipe jacking in the field of equipment and engineering applications are summarized, the development trends of rectangular pipe jacking technology are discussed. The rectangular pipe jacking technology in complex scenarios such as intelligentization, curved jacking, long distance, large crosssection, and composite strata are also explored.
