Background
In recent years, the shield technology is well applied and developed, and the shield method establishes a dominant position in the construction of subways, urban electric power pipe galleries, diversion tunnels and the like due to the factors of high mechanical degree, controllable construction period, safety and the like. The electric power pipe rack transmission line is long, so that the peripheral power supply is convenient to introduce, a plurality of intermediate wells are arranged in the middle of the line, but the shield machine cannot normally start due to the fact that the size of the working well is generally short, and split start is needed, however, the difficulty in transporting and lifting dregs of the shield machine in a narrow space is very high, particularly in weak water-rich stratum, the starting risk is extremely high, and the quick, safe and efficient deslagging is particularly critical after the split start of the shield machine is guaranteed.
The shield machine consists of a shield body and a plurality of sections of rear supporting trolleys, and generally adopts two starting modes of integral and split according to the size of a working well. The whole starting working well meets the requirement of whole machine assembly debugging starting of the shield machine, the generally required distance is longer, the split starting refers to that under the condition that the working well is small in size and does not have the whole starting condition, a shield body and part of trolleys are placed in the starting well, the rest of trolleys are placed on temporary platforms built outside or on two sides of the starting well, after the shield machine is driven for a certain distance, all follow-up equipment is installed in place in a tunnel according to the original sequence, and normal driving is restored.

And then the well head is pulled to an originating well head through a rail and battery locomotive, and finally the well head is vertically transported to the ground through a portal crane of the well head. Because the size of the split starting well is shorter, the assembly of the shield machine occupies a larger space, the slag cannot be discharged by adopting an electric vehicle, the slag is discharged by adopting a self-made 2m 3 slag hopper conventionally, each time 1 ring is pushed in, the slag discharging process needs to be carried out for approximately 24 times, the time consumption of the slag discharging process is longer, and the tunneling speed of the shield machine cannot be met, so that the tunneling speed of the shield machine is limited, the risk of starting construction is increased, and the construction period is prolonged.
