There are two main construction methods proposed for the City Rail Link: Cut and cover where the tunnels are dug from the surface . Tunnelling using a Tunnel Boring Machine (TBM), which travels at some depth below the ground and significantly reduces impact.
Apart from cut and cover and blasting, Tunnel Boring Machine (TBM) is a commonly used construction method in building tunnels nowadays. The type of tunnelling method to be used depends on the specific geology of the project, tunnel length or diameter, logistical arrangements, environmental and other factors.
Cut and cover 1. The "Cut-and-Cover" and "Cover- and-Cut" Techniques in Highway Engineering A. Mouratidis Professor of Highway Engineering, Aristotle University of Thessaloniki Email: [email protected] ABSTRACT The "Cut and Cover" and "Cover and Cut" methods are advanced engineering techniques for tunnel construction in ...
Cut and cover tunnel design with DeepEX. Cut and cover tunnel design involves the consideration of many parameters. Cut-and-cover is a simple method of construction for shallow tunnels where a section is first is excavated and then covered over with an overhead support system strong enough to carry the load of what is to be built above the tunnel.
Cut and cover construction is one of the methods that will be used to build the new Metro Tunnel stations. As the name suggests, cut and cover construction involves using excavation equipment to dig a large trench or rectangular hole in the ground which is then covered by a concrete deck.
