Tunnel boring machine is a heavy mechanical equipment widely used in tunnel excavation and mine construction. According to different classification standards, tunnel boring machines can be divided into multiple types. This article will provide a detailed introduction to the classification method of tunneling machines, helping readers better understand the diversity and functional characteristics of this important equipment.

　　Classified by whether the excavation body and propulsion mechanism are integrated or not

　　Integral tunneling machine

　　Integrated tunneling machine refers to the tight integration of the tunneling body and the propulsion mechanism into a whole. This type of tunneling machine has a compact structure, flexible operation, and is suitable for excavation operations with limited space or complex geological conditions. Its integrated design makes the equipment more stable, reduces the risk of failure caused by loose components, and improves construction efficiency and safety.

　　Split type tunneling machine

　　The split type tunneling machine separates the tunneling body and the propulsion mechanism, and designs and manufactures them independently. This type of tunneling machine is typically used in large tunnels or mining projects. The split design makes the equipment more convenient for transportation and installation, and also facilitates independent maintenance and replacement of each part, reducing the maintenance cost of the equipment.

　　As an indispensable and important equipment in modern engineering construction, tunneling machines have various classification methods, each with its unique advantages and application scenarios. Understanding the different classifications of tunneling machines can help select the most suitable equipment in specific projects, improve construction efficiency and engineering quality.
