MESA TBM-SEGMENT MOULDS are precast moulds which are used to cast segment units for underground tunnels for metro, water utilitiy lines etc.

Main Features;

• Dimensional Tolerance
• Simple Assembly with  Smart Connectors
• Durability
• Ability on Curved Tunnels
• Gasket Type Watertight Joint
• Chamfer Detail on Corners and Edge

Dimentional Tolerances:

• Full plane surface contact in radial and circumferential joints due to the high loads being transferred among them
• Correct linear dimensions to avoid stepping and lipping.
• Correct angles between contact surfaces to minimize birds mouthing or uneven point loads.
• Documentary evidence that only certified segments have been used in the tunnel construction.

Manufacturing Features:

• Certified High Grade Raw Materials.
• Special Hard Alloy Steel for Concrete Faces.
• Mass Production in High Quality.
• High Dimensional Accuracy  on Steel parts.
• Continuous Quality Control.
• Waterproofing at Contact Faces.
• Normalization for Residual Stresses.

Inspection & Tests Before Delivery

• Vibration Test.
• Lifting and Turning Unit Test.
• Connection Test to Form the Ring.

Coating and Delivery:

• Two coats anti-rust paint on the faces not in contact with the concrete.
• Grease on the mechanical parts and the faces contact with the concrete.
• Individual packaging against damaging during transportation.
• Special rubber parts on connection joints and the center connection.

Design Features

• Rigid Chasis Providing Durability.
• Precise Fixing on Variable Concrete Ends.
• Short Time Requirements for Assembly and Dismantling.
• Precise Dimensioning on Connection Points.
• Easy connection of Concrete Vibrators.
• Waterproofing at Contact Faces.
