The TTMJ project is a new joint system providing foundation specialists with the capability to deliver high quality, watertight and effective diaphragm wall joints at lower costs and minimized risks.
TTMJ stands for Tension Track Milled Joint and is an EU-funded project under the framework of Horizon 2020.
The aim of the TTMJ project is to develop, validate and commercialize a new joint system that will provide foundation specialists with the capability to deliver high quality, watertight and safe diaphragm wall joints at lower costs.
The new system, invented and patented by the consortium partner CCMJ System Ltd., offers the possibility to construct profiled joints to increased depth, by maintaining the vertical alignment of the primary panel with a mill or Trimmer that is guided by tracks previously cast into the primary panel (after the secondary panel has been excavated and before it is concreted) ensuring the quality of the joints in the completed diaphragm wall.
Trevi with its considerable experience and know-how in deep foundations, will lead the team, coordinate development, build the prototype trimmer, and trial it in a full-scale field test.
This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 720579.
