Deep Tunnel Sewerage System Phase 2

• Link Sewer; 1x Invert Formwork, 1x M+E Gantry, 1x Gantry Crane 2x Arch Formworks (hit and miss)

• South Tunnel: 1x Invert Formwork, 1x M+E Gantry, 1x Gantry Crane 4x Arch Formworks (hit and miss)

DTSS 2 constructed a 50 km network of deep tunnels and link sewer.

ÖSTU-STETTIN developed an Arch Formwork to carry out a secondary concrete lining together with the HDPE membrane in one working step. With the integrated unrolling device, the HDPE membrane is applied to the formwork and tensioned before the concrete blocks are poured.

This formwork system provides a flexible and effective system for any sewage project!
