The project of "Key Technology and Application of Super Large Diameter Shield Machine" won the first prize of Hunan Provincial Science and Technology Progress Award

The ultra-large diameter shield machine is a powerful tool for crossing rivers and seas, and its service environment often faces challenges such as large sections, high water pressure, and complex formations. With the support of national, provincial and ministerial science and technology projects, with the spirit of "digging roads in the mountains and building bridges in the water", the railway soldiers have independently developed the first domestic 16-meter-level super-large diameter shield machine "Jinghua", China's deepest submarine tunnel shield machine "Shenjiang No. 1" and other major equipment, supporting the construction of major projects in many countries and becoming a successful model created by China.
