Relay type reshipment method and transportation device for earthwork in pipe of earth pressure balance type jacking pipe

The invention relates to the technical field of pipeline construction, in particular to an earth pressure balance type pipe jacking in-pipe earth relay type reshipment method and a transportation device.The working principle of the earth pressure balance pipe jacking in-pipe earth relay type reshipment method is that the single jacking distance is reasonably divided into a plurality of relay sections; and each relay section is provided with an earth moving trolley to realize relay transportation of earthwork in the pipe. The earthwork transportation device comprises the earthwork moving trolleys and the relay station hopper exchange system, the trolleys of the adjacent relay sections achieve transposition of full-load hoppers and empty hoppers in pipes through the relay station hopper exchange system, and earthwork is transferred between the trolleys. Compared with a traditional earth pressure balance pipe jacking single trolley earthwork transportation method, the method has the advantages that the machine h
