The invention discloses a sandwich sinking pipe connector and a production method thereof. The sinking pipe connector comprises an annular steel structure shell composed of a bottom plate, a top plateand side walls connected between the bottom plate and the top plate, the shell is internally provided with a plurality of longitudinal partition plates and transverse partition plates, and all the transverse partition plates and longitudinal partition plates partition the shell into a plurality of mutually-independent compartment units. Each compartment unit is further internally provided with aplurality of stiffening plates and filled with concrete. According to the sandwich sinking pipe connector, in the adopted steel structure shell, the stiffening plates can be in rigid connection with the compartment units in longitudinal and transverse directions, and when each compartment unit is cast again, it is ensured that a shell body and the filled concrete deform jointly, so that the situation that slippage occurs between the bottom plate and the concrete interface, the top plate and the concrete interface as well as the side walls and the concrete interface is prevented, and thus the rigidity and the strength of the sinking pipe connector are ensured so as to adapt to the seabed sinking pipe requirement; and forming is achieved at a time, subsequent maintenance can be omitted, theusing requirement for 120-year durability can be met, and stability is good.
