this ia a presentation presented in college after summer training of civil engineering . this ppt is about single type box culvert.

17.  For establishing location of any bridge we are given center line
chainage of the given bridge.
 Now from GPS survey we can determine the center point location.
For providing better drainage slope of 1 in 100 is provided but slope is
provided before construction of superstructure.
 By turning Auto-level through various angles we can plot layout of
our bridge.
Dimension of all the components of bridge is decided from the data
given by R.D.S.O. Department. According of different fill height.

18.  Cutting Length : It is the length reduced at the bends of
90
degree and 45 degree.
For 90°- 2d
For 45°- 1d
 No. of bars (+1)
 In the wing wall length of each bar is different and is
calculated by considering slope of wall.
 Chairs, Key, Shear link up bars.
 Cover (50mm)

20.  Berms (a narrow path at the edge of a slope, road or
canal.)
 Filling slope
 Compaction after every 400mm layer of filling
 Core cutter test to check dry density after each layer.
 Railway curve (design).
 Cutting by explosions.

24.  Loads considered are :
Dead loads
Live loads
Dynamic effects
Seismic force
Earth pressure
Surcharge pressure
 By moment distribution method we can analyze.
 Loading is calculated by considering 25t loading IRS 2008

25.  Bridge codes : 1785 part 1
 1785 part 2
 1786
 IRS standard 2008
 IRS Bridge Substructure and foundation Code
 IRS bridge rules
 Concrete Mix design 10262: 2009
