- TBM SEGMENT MOULD
Mesa Imalat demonstrates his engineering mastership also in manufacturing of Segment Moulds.
TBM, (Tunnel Boring Machine) which is used to drill underground tunnels in subway, dam and irrigation projects, keeps tunnel security at the highest level, achieves precise reach to the desired spot, reduces the project durations and thus costs considerably, places the precast concrete segments and the concrete rings they have formed in such a way as to form the coating of the tunnel, while excavating the tunnel.
The joint formed by the precast concrete segments is called a “ring”. Rings are used in tunnel projects in different thicknesses and diameters. These diameter changes the number and the geometry of the precast concrete segments forming the ring. The segments that form the ring are composed of two types as “standard” and “keystone”. The keystone segment is the last part of the ring to be completed and provides the fixation of the ring.
