The invention discloses a construction method for a tunnel boring off-contact sending and receiving platform of an up-down overlapped tunnel. The up-down overlapped tunnel comprises an upper tunnel body and a lower tunnel body. When the advancing directions of the upper tunnel body and the lower tunnel body are parallel, the two ends of the up-down overlapped tunnel are provided with tunnel boring vertical wells for sending and receiving of a tunnel boring machine. Each tunnel boring vertical well is provided with a bottom plate, a top plate, a middle support and a counterforce frame supporting middle plate; steel pipe supports are installed on the bottom plate; the tops of the steel pipe supports are sequentially provided with longitudinal double-splicing I-shaped steel and transverse double-splicing I-shaped steel and paved with a high altitude platform built with steel plates and the like; and accordingly the sending and receiving platform of the tunnel boring machine is formed. According to the construction method for the tunnel boring off-contact sending and receiving platform of the up-down overlapped tunnel, the influence of tunnel boring sending or receiving construction on the structure of the vertical wells can be reduced, and the safety of the plate structure is ensured. The construction method for the tunnel boring off-contact sending and receiving platform has very important reference value and practical significance to similar tunnel boring engineering, plate boring sending or receiving during metro interchange, development and utilization of deep and intensive underground spaces and the like.
