REINFORCED SOIL STRUCTURE AT MB ROAD_4
Problem
In Delhi at MB road, a Rail Over Bridge was constructed to Connect the Noida mod to ITO Chungi. It was decided to construct the approach wall as reinforced soil wall. There were two approach walls i.e. towards Vikas Marg side and Towards Noida side and two cross walls. The foundation soil and structural fill was Silty sand . The bearing capacity of founding soil wall was relatively low. In order to avoid extensive foundation improvement schemes, Reinforced soil wall was selected as the solution in stead of conventional Reinforced concrete wall. The structure which ever is adopted will be getting a lot of attention as it is in one of the prime location of the capital city of India.
Solution
Reinforced Soil Wall with concrete panels as facia and Geogrid as reinforcement was selected as the best solution for the above problem. Cruciform shape discrete panel were used as facia. The Standard Panels were Cruciform shaped, some of the top and bottom panels were half panel of varying heights. Some special end panels and corner panels were also used. The connection between the panels & reinforcement was done by Hook and rod arrangement. For the structure Polyfelt rock biaxial Geogrid was used as reinforcement. The height of walls varies from 3m to 12m. The total Facia area was 1210 Sq.m. Speed was satisfactory and project was completed in 8 months. It is the first structure of its kind where Maccaferri India has used geogrid (Woven) with panel.
