(A) State the different types of culverts and give a brief idea for each with using drawing sketches. (B) A plain area of km^2, the average runoff coefficient 0.5, the average value of the rain intensity of the whole area 110 mm/day. To protect the road crossing this area from the torrent water(runoff) falling in this area, a steel pipe culvert under the embankment of the road should be constructed to drain the torrent water: Data given:- Road level(Bank level)or (R.L)or(B.L) = (16.0). Land Level (L.L) = (15.00). Upstream high water level = U.S. H.W.L = (14.00). For Steel, a = 0.003 & b = 0.029. Road Width = 17 m. Side Slope of the Bank 2:1. Specific weight of dry earth = 1.8 t/m^3 Angle of contact of soil = Theta = 30 degree. The maximum heading up not to exceed = 19 cm. Specific weight of Steel = 7.8 t/m^3 The moving load is to estimated equivalent to distributed live load(P) = 1.5 t/m^2 velocity approach = 0.81 m/sec. Design a steel pipe culvert. Draw to scale 1:100 the required following views, (a) Plan half earth removed (plan H.E.R) (b)Section Elevation along the center line
