Strengthening & Widening of Road at Palanpur - Swaroopgunj Package on NH-14
Size of the panel has been selected by the client, i.e. 1.25m x 0.6m. It has been decided to use this panel with PET Geogrid with friction / tongue and groove connection. Designs must be checked for the connection strength for this type of panel-Geogrid arrangement
Testing has been done at IIT-Madras for the friction based connection for Techgrid-PET with this
Design has been checked and verified with consideration of test results and ensured the
tension in Geogrid is less than the available connection strength at particular normal pressure
The design of the walls was carried out using the BS 8006: 1995 for Static Condition & FHWANHI- 00-043 for Seismic Condition, which comprised checks for external, internal and global stability under static and seismic conditions.
Construction of the wall was carried out under the supervision of TechFab India Industries Ltd’s supervision. The project was successfully completed in November 2009.
