Study on Shield Machine Technology

Abstract

The shield machine is a specialized construction equipment used for excavating tunnels, particularly in underground construction projects. The shield machine plays a pivotal role in modern engineering and construction, minimizing surface disruption and environmental impact. Shield machines can adapt to different geological conditions and project requirements, and efficiently excavate tunnels in various ground conditions, reducing construction time and costs. Shield machines improve worker safety by reducing risks associated with manual tunneling, and digging tunnels with high precision, crucial for projects like subways. In essence, shield machines are essential tools in modern tunnel construction, offering efficiency, safety, and precision in building underground infrastructure for various purposes, including transportation, utilities, and more. This paper summarizes the development history of the shield machine and its basic structure, discusses its limitations and challenges, and makes a certain analysis of the application of the shield machine while discussing the innovations and methods of the hydraulic propulsion mechanism of the shield machine. This paper may offer a reference for the development of shield machine.
