The huge blade crazily flaunts food, and the rocks instantly shatter into pieces!

Previously choked by foreign technology? It doesn't exist! Previously choked by foreign technology? It doesn't exist!
Back in the day, shield tunneling technology was firmly held in the hands of foreign countries, and our tunnel construction was like being stuck at the neck! But Chinese engineers directly activated the "open hanging mode", and Dingye Exhibition Institution became a super god "equipment manufacturer", polishing technology day and night, and creating a Chinese made shield machine model artifact with a bang! From imitation to surpassing, Made in China has been making a comeback all the way, directly maximizing efficiency!

In addition to conventional fields such as subway and transportation, the technological innovation of Chinese shield tunneling machines is driving global infrastructure deeper; Underwater at over 100 meters, harder; The compressive strength of the rock is 300 MPa+. For example, the "Herrenknecht China Railway" shield machine exported to Singapore participated in the construction of the subway ring line, and the ultra large diameter shield machine exported to Europe was used in the double track project of the English French underwater tunnel, fully reflecting the core competitiveness of "Chinese equipment" in global infrastructure. Recently, I heard that they will evolve into an intelligent version that can diagnose faults, plan routes, and be even more intelligent; The development of 5G remote control direction. This is going to crush the rhythm of our peers!
