Abstract

A method for tunnelling uses equipment comprising a tubular structure (10) with a substantially empty tubular cavity corresponding to the cross section of the tunnel to be constructed. The front portion (13) of the tubular structure is placed close to the excavation face (F), which is made to advance over a predetermined distance by means of excavation with one or more excavators moved into the tubular cavity to a point close to the excavation face (F). In a rear area of the tubular structure, at least one course of segments is laid, and pushing members (22) then bear on these segments, causing the tubular structure (10) to advance over the predetermined distance until the front portion (13) is brought to a point close to the excavation face (F). The steps are then repeated until the tunnel is complete.
