Temporary shaft structures are essential for TBM start-up and breakthrough. Geological uncertainties, tunnelling below the water table, cramped shaft or portal conditions, detailed interface clarification for the TBM used and the need to make the process safe place high demands on the systems used.  

Our sealing systems protect the shaft from water and soil ingress, while support solutions effectively transfer loads to the ground.  

A comprehensive range of services includes detailed process definition, preparation of BOMs, structural analyses, site assembly and provision of appropriate lifting systems.

Solutions for start-up and sealing systems

Sealing systems

Reliable protection against water and soil

The sealing systems prevent water and soil from entering the shaft, especially when working below the water table. They provide stability for the entire structure and enable safe TBM operation even under challenging conditions.

Reaction frame with thrust rings

Firm support for maximum thrust forces

The reaction frame with its thrust ring provides the necessary support for the TBM start-up process. It distributes the enormous thrust forces evenly across the launch shaft for a safe and stable launch even under high loads.

Shield cradles

Precision and stability for a safe TBM launch

The shield cradle positions the tunnel boring machine in the launch shaft with millimeter precision. It stabilizes the equipment weighing several tonnes, positions it precisely on the planned tunnel alignment and safely transfers the thrust forces generated during start-up to the reaction frame. This enables a precise and smooth TBM launch.
