Gondal, Gujarat, India | Keval Construction
The old road overbridge (39A) in the prime area of Gondal (Gujarat) was not in alignment & was in skew. As a result, lots of traffic issues were experienced and further deterioration of bridge was anticipated. To fix this, reinforced soil wall with panel facia was nonstructured, after carefully studying geotechnical parameters of the land & soil of the surrounding area of the bridge.
The project scope included reconstruction of ROB in the prime area of Gondal (Gujarat), wherein the alignment of old ROB was in skew. Considering the city congestion and adjoining private lands, alternate alignments were not an option. For the current structure, maximum height of retaining wall was evaluated to be approximately 11m. With due consideration to limited right of way; minimizing land acquisition; poor ground conditions; economy and speed of construction, the consultant has recommended to adopt reinforced soil structure for the approached of ROB in the current project.
Pursuing the detailed geotechnical investigations and the site conditions, it was decided to adopt the reinforced soil wall with panel facia and TechStrap (Geostrap) as reinforcement compared to other alternatives such as RCC retaining walls / gabion gravity walls etc. Following are some of the advantages of adopting reinforced soil walls with panel facia and techstrap reinforcement:
Simple and rapid construction procedures and do not require heavy machinary / equipment
Construction space requirements shall be minimal in front of the structure.
Pore-water pressure will not be developed.
Its flexibile in nature which can to absorb deformations.
Deep foundation were not required as less pressures will be exerted on the foundation soil.
Cost effective and aesthetically pleasing compared to other alternatives.
The project was successfully completed in October 2020. Reinforced soil wall with panel fascia was built using the material supplied by TechFab & was implemented in very less time, ensuring minimal disruption of traffic as it is in the prime location. Also, it has solved the core issues of strengthening ROB with economical cost.
