What Does Emergency Recovery Shaft Mean?

An emergency recovery shaft is an unplanned passage required for the removal or repair of trenchless construction equipment. It is a vertical excavation that is created out of necessity when something does not go according to plan. The design of the shaft will depend on the terrain and the structures that may exist at the site.

An emergency recovery shaft is also referred to as a rescue shaft.


Trenchlesspedia Explains Emergency Recovery Shaft

In the unfortunate event that equipment becomes stuck or broken during a trenchless operation, an emergency recovery shaft is excavated. It makes sense to take the most direct route to access the equipment, which may mean the creation of a vertical shaft.

The cause of an obstruction may not become clear until a rescue shaft is dug. Special measures may need to be taken to repair equipment. This may require remote cameras or other special devices.
