ABSTRACT

 

The campus of RVCE (the premier engineering institute) in outskirts of Bangalore has the River Vrishabhavathi as its boundary on South and Eastern sides. During the rainy season, the river level goes up and inundates the campus and creates problems for inmates of the hostel situated on its banks. With the industrial development in the vicinity of the river and the discharge of waste water, the river water is highly contaminated and is posing health and allied problems for the inmates of the campus. A compound wall built all along the boundary on river bank, collapsed due to the force of flood water and a lasting solution was needed. To study and suggest the lasting solution to the problem, RVCE authorities contacted United Foundations Pvt. Ltd. to study the ground realities and suggest a system which would sustain the fury of floods and help improve the utility of the area along the river course. On careful study of the ground realities and geophysical condition of the site, the team from United Foundations Pvt. Ltd. suggested a system of contiguous piles driven all along the boundary which would act as a permanent retaining wall and dissipate the energy of the flood water with the semicircular shape of piles placed in the row creating corrugated front acting as energy dissipaters. At places where the anchor depth in the bed is not sufficient, shear pins are used to provide required anchors for the piles. With the capping beam on the top of piles acting as the tie and also as the means to hold back the piles with the system of anchor beams placed at intervals. By providing a cantilevered slab overhang on river side of the pile to the extent of original boundary now in river course due to scouring, the area on the campus side can be utilized for a peripheral road and provide a river front as well. It is particularly interesting to mention here that during construction period itself, the part of the new system experienced the fury of flood and has withstood the same successfully.
