  China Railway Shanhe No. 1 shield machine topped the hardships: to overcome 40 ‰ large longitudinal slopes (large longitudinal slopes seriously affect the shield horizontal transportation, battery car is prone to skidding, horizontal transportation risk is greater) and the construction of small curve radius turn test; across the 410 meters of the Pearl River (subject to the impact of navigation management, the Pearl River within the scope of the borehole has not been carried out geophysical surveys). Shield tunneling through the Pearl River under the existence of gushing, shield tail leakage of sand and water, riverbed collapse and other risks, once the tunnel into the water, will seriously affect the safety of construction workers in the tunnel, resulting in economic losses, while the construction schedule is seriously delayed. In less than 8 months, China Railway Shanhe No. 1 shield machine successfully completed the difficult metro tunnel penetration task of 1,482 meters, fully highlighting the excellent quality of Shanhe intelligent equipment.
