Soil body transfer method for tunnel connection channel

The embodiment of the invention provides a soil body transfer method for a tunnel connection channel. A belt conveyor is adopted for operation, and the belt conveyor comprises a first belt conveyor. the soil body transfer method for the tunnel connection channel comprises the following steps that an upper step of the tunnel connection channel is excavated; the first belt conveyor is placed on theupper step formed by the tunnel connection channel; the soil body of the upper step is placed on the first belt conveyor; and the first belt conveyor is started, and newly excavated soil of the upperstep is conveyed out of an opening of the tunnel connection channel. A constructor places the soil body generated by excavating the upper step on the first belt conveyor, and conveys the soil body outof the opening of the tunnel connection channel by operating the first belt conveyor. Along with excavation of the upper step of the tunnel connection channel, the generated soil body is directly transported out of the opening
