It is understood that the amount of tunneling using the shield method accounts for 45% of the total subway construction in Beijing, and a total of 17 shield machines are effective for subway construction. Although the cost of the shield machine is high, it can increase the efficiency of subway excavation by 8 to 10 times, and during the construction process, there is no need for large-scale demolition on the ground, no blocking of traffic, no noise during construction, no ground settlement, and no impact on the normal life of residents. However, large shield machine technology has high added value and complex manufacturing process. Only a few companies in Europe, America and Japan can develop and produce.
