DESIGN OF BOX STRUCTURE FOR ROAD CROSSING THE CANAL

Scheme :Upper Tunga ProjecClient : Karnataka Neeravari Nigam LtdConsultant: Karnataka Power Corporation Ltd

Case : IRC loading the vent+water in the canal+trafic on service road

The box structure is proposed for the road to cross the canal. The difference in formation levelof road and the Upper Tunga Canal, at 124the Km, the road is designed to run below the canalthrough the box structure. As per the IRC requirements the box structure should be minimum5m in height. The height increased by 0.5m as per the clients requirements. The structureshould be founded on the compacted murrum/garnular soil/MSM in layers of 30cm & whosebearing capacity shall not be less than 30t/sq.m

The design is based on the IS 456, is 6403, IS 2131, IS 2950, IS 8009, IRC 21, IRC 78, IRC 89etc., and standard books on irrigation structuressize of vent=

Therefore ,

fc= 55.81 Kg/sq cms okay

Therefore, ta = m fc (D - k D - n) / n
