This invention introduces a novel method using boulders and construction waste to displace underlying soft clay and compact fill material. Dynamic compaction further enhances stability, reducing settlement and accelerating consolidation. Cost-effective and efficient, this approach addresses critical infrastructure needs while minimizing environmental impact and maximizing sustainability in coastal land reclamation.
Figure (1) illustrates a reclamation of a site of costal land in accordance with the present disclosure.
Coastal regions designated for critical infrastructure projects such as sea ports and smart cities are hindered by the presence of soft and sensitive marine clays. Existing reclamation methodologies, involving techniques like PVD (Prefabricated Vertical Drains) installation and stone columns, are plagued by excessive time requirements, cost inefficiencies, and constraints in natural resource availability. These limitations often prevent the adoption of these methods, jeopardizing project timelines and sustainability goals. There is need for efficient reclamation method that can effectively displace underlying soft clay, compact fill material, and ensure stable infrastructure development.
- Innovative Fill Material: Combines boulders and construction waste for effective clay displacement and sustainability.
- Adaptive Filling Strategy: Uses trenches and stages for optimal compaction and minimal settlement.
- Precision Dynamic Compaction: Ensures thorough clay displacement with minimal equipment and reduced environmental impact.
- Environmental Sustainability: Incorporates recycled materials and drainage-friendly fill for eco-friendly coastal reclamation.
The prototype utilizes a combination of boulders and construction and demolition (C&D) waste as fill material. The prototype's dimensions vary depending on the specific project requirements, with typical trenches being 1 meter wide and up to 5 meters deep. Performance metrics include settlement rates and stability measurements, ensuring effective clay displacement and compaction to support infrastructure development in coastal regions. This approach stands out for its cost-effectiveness and environmental sustainability, making it a practical choice for large-scale coastal reclamation projects.
Already implemented at NMIAL (Navi Mumbai International Airport Limited).
