The document summarizes a student group's summer training project constructing a box culvert for the North Western Railway in Banswara, India. It describes the project details, components and materials of the box culvert, laboratory and field tests conducted, concrete mix design, construction layout, execution process, and structural analysis considering various loads. The students gained hands-on experience applying their classroom knowledge to the real-world construction of the box culvert.

4. Object Of
Summer Training
 Application of knowledge and techniques learnt in the classroom to real
field problems and to test out and enrich one’s understanding,
knowledge and skills.
 Gives an insight into the working of the real sites.
 Gaining deeper understanding in specific functional areas.
 Appreciating the linkages among different functions.
 Helps in exploring career opportunities in their areas of interest.

5. Introduction of
ProjectThe project of Ratlam dungarpur
railway line via Banswara was sanctioned in 2011.
176-km-long railway line out of which 126 km
would be in Rajasthan while 50 would be in
Madhya Pradesh. The estimated cost of the new
line, to be completed in five years, is Rs 2,083
crore. The Railway Board and the state
government will bear 50% each of the project
cost, while the land cost, including acquired land
compensation, would be borne by the state
government. The state government's move to allot
Rs 1,200 crore for the project as its share.

6. BOX CULVERT
 BRIDGES
 A bridge is a structure having a total length above 6m
between the inner face of the dirt.
 Classified as:
 Minor Bridges – Span greater than 6m upto 60m
 Major Bridges – Span greater than 60m
 CULVERT
 A culvert is a cross-drainage structure having a total length
of 6m or less between the inner
 The types of culverts are:
 Box Culvert
 Pipe Culvert
 RCC Solid Slab Culvert

8. Components of Box
Culverts
 Bottom Slab
 Vertical walls
 Deck Slab
 Haunch
 Wing Wall
 Return Wall
 Drop Wall
 Curtain wall
 Earth Retainer

10. MaterialsUsed InConstrucion
 Cement (OPC 43 grade)
 Coarse aggregate (20mm)
 Fine aggregate(sand)
 Super plasticizer
 Steel (fe 500, rubbed bars,TMT)
 Shuttering (couplar,box channel)


 Boom Placer
 Hydraulic Excavator
 Auto level
 Batching Plant (Mechanically
operated)
 Needle Vibrator

EquipmentUsed:

14. LaboratoryTests:
 Compressive Strength Test
 Aggregate : 1. Impact value
 2. Crushing value
3. Los angles
4. Pycnometer test
 Sand : Sieve Anaylysis
liquid limit
 Specific gravity indicates amount of water
that an sample can absorb in its pore

15. FieldTest:
 Slump cone test : 150mm slump
 Layout of any culvert using Auto Level.
 Chainage : It is distance travelled along a survey line
starting from a fixed commenced point.
 Building of Dungarpur Railway Station is starting point
i.e. chainage is 0 at dungarpur railway station.
 Slope is provided at layout time by fixing center
chainage of culvert.

18. ConcreteMixDesign:
 IS 10262 : 2009
 M35 concrete is to be designed.
 Slump required- 125mm-150mm
 Admixture : Super –Plasticizer
 Crushed Angular Aggregate
 W/C ratio :0.4
 NOTE : For getting desired slump content of admixture can’t be
increased we have to redesign concrete in that case.

21. Layout of Construction
 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 Autolevel through various angles we can
plot layout of our bridge.
 Dimension of all the components of bridge is decided

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

24. Executionofconstruction:
 200mm thick sand layer.
 150mm thick pcc base course (M20).
 Survey after sand and p.c.c layer also to check bed slope.
 Pouring of concrete not with a height greater than 1.5 m
 Shuttering load(450mm)
 150mm thick boulder outside bridge.
 Range of vibrator
 150mm thick wearing course at bed level.

26.  Burms
 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

30. Structural Analysis
 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
