PANTEX Lattice Girders have been developed for special demands in the field of Tunneling. The PANTEX system has been extensively tested and used successfully for numerous tunnel projects throughout the world.

PANTEX Lattice Girders ensure an immediate support in the open span area. Contrary to standard solid-web girders, PANTEX Lattice Girders are entirely integrated in the shotcrete lining; porous zones and shotcrete spray shadows are avoided.

The load-bearing capacity of PANTEX Lattice Girders has been investigated with various loading tests and by numerical analysis. Flexibility regarding geometry and bearing capacity characterize this passive support system for underground applications.

■ Immediate support in the excavation area

■ Utilization as a true-to-form template for shotcrete application

■ Easy and quick assembling, simple handling

■ Optimum bond and interconnection with the shotcrete lining

■ Simple adjustment and shaping to the excavation geometry

■ Ideal bearing for spiles and lagging boards

■ Spiles may be installed both above or through the lattice girders

System Description

■ Load-bearing elements according to the particular demands in Tunneling

■ Spatial 3 or 4 bar girder construction, connected via stiffening elements

■ 3-bar girder: single bar either at the excavation or ground side, depending on the application

■ 4-bar girder: application as wallplate beam or stiff cross girder

■ Reduction of girder buckling lengths by stiffeners

Fields of Application

■ Passive support system for the excavated cross section

■ Profile template for the excavation geometry

■ Bearing for pre-support elements

Main Advantages

■ Assembly of the full girder profile by connecting single girder elements

■ Load transmission even before shotcrete application

■ Integral part of the shotcrete lining reinforcement

■ Proven bond according to the design principles of reinforced concrete
