Abstract: Tunnels are used for many purposes. In a large scale, it serves as a mass rapid transport for people especially in urban and built-up areas. In a smaller scale, one can find uses in pipe jacking for laying of sewer line without opening out the ground and disrupting the flow of traffic. Various types of tunnelling methods are described in the report. Among the methods, the compressed air technique is the least useful and has the greatest health hazard. Others, like the pressurised face method, combine a tunnelling shield and the use of fluid such as slurry to stabilise the excavated wall surface similar to those found in diaphragm wall construction. The pressurised method has several modifications as one can see in this report.
