Project description
Steel structure supporting a 2.4 m diameter GRP (Glass Fiber Reinforced Polymer) pipe for the left bank - right bank connecting channel of the Rhinau fish pass (67).
European project to restore fish continuity between the North Sea and the Schaffhausen Falls (Switzerland).
Total length of steel structure: 128 m Function of structure :
2 vertical lattice girders and 1 horizontal lattice girder forming a U with uprights spaced according to GRP supports
GRP cradles to prevent buckling of top chords
2 supports on metal brackets at each end of the trusses
Metal brackets in line with each stack
Challenges to meet
Installation of above-water structures and anchors with continuity of power plant operation
Lifting the structures from a road bridge over the dam piers with a large overhang
GRP pipe stresses (low rotation at junctions)
Success factors :
Collaboration of all stakeholders throughout the project
Mutual trust between parties
Numerous exchanges between players
The benefits of BIM and Trimble solutions :
Use layout manager with layout point macro to export coordinates
Working with the existing environment
Easier management of interfaces (anchors, pipe supplier, new and existing civil engineering structures, etc.) with the various parties involved
Simplified exchanges thanks to visualization and sharing of information throughout the project
