Since Brunel's square shield, shield technology has been improved for 23 years. By 1869, Great was responsible for the construction of the second tunnel across the Thames. From the repeated failures of Torevix at the beginning, to Brunel's shield construction method , and then improved into Great's shield construction method, which lasted for 80 years.

1. Since Brunel’s square shield, shield technology has been improved for 23 years. By 1869, Great was responsible for the construction of the second tunnel across the Thames River. From the repeated failures of Torevix at the beginning to Brunel’s shield The shield tunneling method was then improved to Great's shield tunneling method, which lasted for 80 years.

2. From the 19th century to the middle of the 20th century, the shield tunneling method was successively introduced to the United States, France, Germany, Japan, the Soviet Union and other countries, and developed to varying degrees. During this period, although the shield tunneling method made certain progress, this During this period, the main focus was on the promotion and popularization of shield construction methods in various countries around the world.

3. From the 1960s to the 1980s, shield tunneling methods continued to develop and improve, with remarkable results. During this period, a variety of shield tunneling methods emerged, with mud-water and earth pressure shield tunneling methods being the main ones.

4. From 1990 to 2003, the technological progress of shield construction methods was extremely significant during this period: shield tunnels became longer and larger in diameter; shield tunnels were diversified, with rectangular, elliptical, multi-park and overlapping shapes appearing. A special round cross-section shield; construction automation, shield tunneling direction and attitude automatic control system.
