Effectiveness of Prefabricated Vertical Drains Over Conventional Sand Drains in Indian Railway Project

K. Vairakannu, Dr. R Jayanthi

Abstract :

The construction industry in India has grown tremendously with technological advancement in large number of mega projects in roads, railways, urban infrastructure, ports, Airports, space research and renewable energy sources. Due to the massive urbanization infrastructure development along the coastal belt experiences a compulsion to utilize the soft clays as foundation for road networks, ports and rail road. The consolidation settlement of soft clay subsoil creates a lot of problems in foundation and infrastructure engineering. Because of the very low clay permeability, the primary consolidation takes a long time to complete. To shorten this consolidation time, vertical drains are installed together with preloading by surcharge embankment or vacuum pressure. This study takes a specific case in construction of proposed oad gauge line from Nagappattinam to Thiruthuraipoondi along the east coast line in Tamilnadu where the coastal belt contains soft clay deposit needs to stabilize before commencement of the project. The advantages of using perforated vertical drain over the conventional sand drains are also discussed.
