Tunnel Lining Segment Mould is tailor-designed for the production of precast concrete lining segments in shield tunneling. Compared to other types of moulds, the design and manufacturing requirements of the segment mould are both strict. The quality of the formed tunnel structure is inseparable from the quality of the precast concrete segments, while the quality of the segments depends to a large extent on the quality of the steel segment mould.

Characteristics of shield tunnel segment mold:

>High precision mold processing

>Continuous production without deformation

>Adhesive vibration compaction

>Embedded sealing without leakage of grout
