Product Description

Optimas International supplies guiding rods for precast concrete tunnel segment radial joints, combining sustainable recycled-plastic construction with project-specific engineering and supply.

From metro to sewer tunnelling, we help contractors and precast manufacturers direct segments into position faster, with less manual correction during ring placement.

Application

Engineered for Accurate Segment Placement

Guiding rods are used during the installation of precast concrete tunnel segments to help guide each segment into the correct position as it is erected. By helping align adjoining segments, they reduce the need for manual adjustment and support a more controlled installation process.

Optimas International supplies guiding rods for a range of tunnelling applications, including metro, rail, road, utility and sewer projects. Dimensions and placement are matched to the tunnel segment and ring design, helping the rods work effectively within the wider tunnel construction system. Guiding rods form part of our integrated radial joint solution alongside dowel systems, bolting systems and shear cones, helping ensure the different components work together during segment installation.

Materials and Quality

Materials, Finishes and Quality Matched to the Application

Our guiding rods are manufactured from 100% recycled plastic, offering a lightweight, cost-effective solution.

Dimensions and placement are matched to the project-specific segment and ring design and range from 30mm to 80mm with varying shear resistance based on length and diameter. Because guiding rods remain embedded within the joint during construction, consistent quality and dimensional accuracy are maintained across the segment order.

Frequently Asked Questions

Guiding rods are used to help position precast concrete tunnel segments during installation. Fitted within the radial joints, they guide each segment into the correct position as it is lifted into place, reducing the need for manual adjustment.

Optimas International guiding rods are manufactured from 100% recycled plastic. This provides a lightweight installation aid for positioning precast concrete tunnel segments.

Guiding rods can be used in a range of tunnelling applications, including metro, rail, road, utility and sewer projects. They are used during the installation of precast concrete tunnel segments.

Yes. Guiding rods typically work alongside other tunnel joint components, including dowel systems, bolting systems and shear cones. Together, these components can form part of an integrated radial joint solution for precast concrete tunnel segments.

OPTI.Fix® provides a more efficient method for fixing sockets within segment moulds, helping save time during installation and demoulding while reducing maintenance and supporting improved production consistency and automation.

Our OPTI.Fix® guiding rod solution uses plastic studs which prevents glue usage at the precast factory.
