Pipe Jacking-pull technology is a new technology of trenchless pipeline construction,which has good applicability under different construction conditions.In view of the construction quality,costing and etc.of pipe jacking-pull technology,an introduction to its process principle,quality defect improvement and costing level is made,complete with the developing prospects.The comparative analysis is carried out for the process characteristics,causes for the problems and on-site construction exploration means,which shows the advantages of pipe jacking-pull in process and costing as well as defect avoidance methods.It is found that the pipe jacking-pull has higher construction accuracy than that of pipe dragging process,lower cost than that of pipe jacking process,ensures higher construction quality by water-stop at work-hole and giving priority to tension force in the construction.
