Definition of China Tunneling Boring Machine
In China, Tunneling Boring Machine is referred to as "TBM" for short, which is used in the soft soil layer as a (narrow) shield machine. Definition of Tunneling Boring Machine includs includs broad sense and narrow sense.
1. Broad Sense of Tunnel Boring Machine
Tunnel Boring machine It is divided into open tunneling machine and generalized shield machine. Excavation, supporting, slag, such as construction process parallel continuous operation, machine, electricity, liquid, light, gas system integration, such as factory assembly line tunnel construction equipment, has the tunneling speed, environmentally friendly, high comprehensive benefit, etc. It can realize the traditional drilling and blasting method is difficult to implement complex geological features of deeply buried long tunnel construction, railway in China, such as water and electricity, transportation, mining, municipal tunnel engineering applications is growing rapidly.
2. Narrow Sense of Tunnel Boring Machine
Compared with the narrow shield machine, TBM is called the "king of the driving machine" due to its high reliability and long life requirements.
The Tunnel Boring Machine, or shield Machine, is an abbreviated TBM, which is a large Machine tool used for excavating tunnels. Whole section Tunnel boring machine was born in 1853, the designer for Charles Wilson, first used in western Massachusetts, Mr Paul for Tunnel (Hoosac Tunnel) excavation, excavation and supporting in the shale Tunnel wall. The tunnel was damaged after only a 10-foot advance, and the tunnel was later converted to a traditional artificial excavation, which was delayed until 1875. The first successful use of the full-section tunneling machine was the Oahe Dam in south Dakota, which was put into use in 1952 and was completed in 1962. However, the opening of the tunneling machine was still delayed until 1988.
