Tunnel boring machine is a kind of heavy engineering machinery with world advanced level and high technical content. It integrates various high-tech technologies such as hydraulic, electromechanical control, laser guidance and control, computer, etc. It is widely used in tunnel construction and urban subway construction. It is currently entering related industries and fields with an ascendant momentum and becoming a typical product representing the level of heavy equipment manufacturing in a country. Chengdu is located in the Chengdu Plain, which has a sandy gravel layer and high water-rich geological structure. It is the city with the most complex geological conditions and the greatest difficulty in excavation among the cities with subways currently opened in China. The earth pressure balance shield machine carefully built by our company can provide a complete technical solution and effectively reduce costs.

On the evening of November 28, 2012, at the shield tunneling promotion meeting of the Chengdu Metro Project Department, the leadership team of the project department decided that the second shield machine would be assembled by its own crew, marking the official start of the first batch of shield tunneling crew members of the Chengdu Metro Project Department.

On November 29, 2011, all members of the project department's electromechanical department, led by the company's deputy chief engineer Xia Ling, began to be fully responsible for the assembly of our company's 53#CTE6250 shield machine. The company's deputy chief engineer Xia Ling and the project's deputy manager Yu Changjiang took turns to lead the team on site. During the assembly process, the site was in order. Through on-site operations, not only did the crew's business level increase, but also talents were cultivated for the project department and the company.

During the assembly of the second shield machine, the company's deputy chief engineer Xia Ling and the project's deputy manager Yu Changjiang supervised the work of the installers to prevent damage to the shield machine; on the other hand, they actively carried out technical exchanges with the installers, which not only accelerated the speed of assembly and commissioning, but also accumulated experience for future work.

The shield machine assembly process is complex and requires high standards for personnel and equipment configuration. The technical personnel strictly demanded themselves, and the Chengdu Metro Project Department successfully completed the shield machine assembly.
