Zusammenfassung:	The invention particularly relates to a branch section reserving and re-communicating construction method for long-distance continuous pipe jacking. The problem that long-distance continuous pipe jacking cannot be achieved due to the fact that a branch section is arranged in an existing pipe jacking process is solved. The branch section reserving and re-communicating construction method for long-distance continuous pipe jacking comprises the steps that S1, prefabricating a connecting device, wherein the connecting device comprises a connecting pipe and an outer protection pipe; S2, prefabricating a re-communicating device, wherein the re-communicating device comprises an inner sleeve and an outer sleeve; S3, prefabricating an outer sealing pipe; S4, mounting the connecting device; S5, conducting pipe jacking operation; S6, excavating an inspection well; S7, dismounting the connecting device; S8, mounting branch pipe fittings; S9, mounting there-communicating device; and S10, setting anexternal function protec
