The invention discloses a construction method capable of synchronously constructing close range overlapped subway tunnels and reserving shield empty pushing conditions. The construction method comprises the following steps: placing an intersected section of two railway sections in the same foundation pit, and excavating; in an excavated foundation pit, firstly constructing a structure at a lower railway section, then constructing a structure at an upper railway section, then plugging outside a shield cavity, earthing and backfilling except a hoisting hole, and restoring a pavement and traffic;and finally enabling four shield machines to sequentially pass through the node according to a specific construction sequence, and completing construction of a tunnel. The construction method disclosed by the invention has the advantages that integrated construction is carried out on the intersected section of two railway sections, conditions for a railway section shield to underneath pass the intersection in a later period are reserved, a newly constructed railway section safely passes the intersection and backfilling and earthing are carried out timely without influencing traffic on ground,and an existing railway structure and ground traffic are not influenced when the railway section safely and rapidly passes the intersection in the later period.
