Benefits of Shafting for Tunnel Engineering

They greatly expedite the work by adding two faces per shaft for driving.

They afford outlets for excavated material and means of access into the tunnel for building materials.

They could be used as pumping shafts in case of a large influx of water.

They help correct alignment and help carry the center line into the tunnel properly.

In long tunnels, they afford ventilation and are helpful for exhausting smoke and foul air out of the tunnel.

The shaft also acts as an escape route in accidents.

FAQ

Q: What are tunnel shafts?

A: Tunnel shafts are vertical channels that link the surface of the ground to the upper part of a tunnel during the tunnel's construction (Figure 1). There exist various techniques for supporting shafts. When dealing with groundwater, it is recommended to employ a watertight support system.

Q: What is the maximum diameter for pipe jacking?

A: Pipejacking is a technique used to install underground tunnels, pipelines for gravity systems, conduits and culverts. It is a very well proven method of small diameter (typically up to 3m diameter) tunnelling over modest distances (typically less than 500m, although longer tunnels are possible with specific equipment).

Q: What is the purpose of the main drive shaft of a pipe jacking machine?

A: The Main drive shaft of pipe jacking machine is central to underground pipeline laying. When the motor starts, power is transmitted through high - precision keyways to the cutterhead, which rotates at a preset speed to cut soil. With high - strength material and fine structure, the shaft bears axial force and torque, coordinating with seals and bearings to steadily push the pipe - jacking machine for trenchless pipeline laying.
