Training report done on Bridge ConstructionSukhdeep Jat
The document provides details about an in-plant training report submitted by Sukhdeep Singh Jat at BSCPL Infrastructure Pvt. Ltd during the construction of a bridge over the Mahanadi River in NH-53 in India. It discusses the company profile, ongoing major projects including road and bridge construction projects, and specifics of the bridge project over the Mahanadi River including the design process, materials used such as different grades of concrete, and machinery employed.
The project involved designing of two different types of Rigid pavements using the
AASHTOWare Pavement ME software.
1) JPCP (Jointed Plain Concrete Pavement) : It was designed as a three layered structure,
the layer distribution being as follows:
Layer 1 – PCC – 16 inch
Layer 2 – NonStabilized (Crushed gravel) – 8 inch
Layer 3 – Subgrade (A-1a) – Semi Infinite
Jointed plain concrete pavement uses contraction joints to control cracking and uses
reinforcing steel in form of dowel bars.
Transverse joint spacing is selected such that temperature and moisture stresses do not
produce intermediate cracking between joints.
This typically results in a spacing no longer than about 6.1 m (20 ft.).
2) CRCP (CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS) : It was
designed as a 4 layered structure, the layer distribution being as follows:
Layer 1 – PCC – 11.3 inch
Layer 2 – Stabilized – 4 inch
Layer 3 – NonStabilized – 8 inch
Layer 4 – Subgrade – Semi infinite
CRCP is concrete pavement reinforced with continuous steel bars throughout its length.
Its design eliminates the need for transverse joints (other than at bridges and other
structures) and keeps cracks tight, resulting in a continuous, smooth-riding surface.
BSCPL Infrastructure Pvt. Ltd is constructing a four-lane bridge over the Mahanadi River in Chhattisgarh, India as part of a contract to reconstruct 250 km of National Highway 53.

Procedure and construction of road under bridge by box pushing methodeSAT Journals
Abstract The intersection of railway track and the road at the same level is referred to a level crossing. In the urban areas the level crossing are generally monitored by qualified railway personnel who monitor the train movement and close the level crossing gate to stop the interfering road traffic but such closing of gates leads to congestion in road traffic and also causes loss of time to road users. Road under bridge and road over bridge are considered as solutions for avoiding level crossings of roads and railway track. There are 3 main methods in construction of road under bridge. Box pushing method, Cut and cover method, Rolling technique using RH girder. In this we discuss about the implements, soil friction, effects required, capacity of jacks and there uses, skew angles and at square angles. Keywords: Road Under Bridge, Level Crossing, Box Pushing Method and RUB etc
Segmental bridge construction involves building bridges out of precast concrete segments. This allows for longer spans than traditional methods by reducing the need for intermediate piers. There are several techniques for segmental bridge construction including cast-in-place using form travelers, incremental launching where segments are cast and then pushed out over supports, and precast segment erection using launching girders. Segmental construction enables building bridges more quickly and over existing infrastructure with minimal traffic disruptions.

9. 3. PRE-CASTING WORKS
OFF SITE WORKS :
The offsite works generally refers to structures built at a different
location than the location of use. Thus this process benefits for
reduction in time for construction and also solves the problem of
limited space availability at site.
For pre-casting of segments in HMR, the following works are spotted
under off site works:
Establishment of casting yard
Mould fabrication
Segment casting
10. 3.1 ESTABLISHMENT OF
CASTING YARD
The casting yard is a place where the segments are
casted, stacked and tested for strength before the segment
placement at site.
The HMR has established two casting yards at UPPAL
and QUTTBULLAPUR which are well equipped for
segment casting and free from traffic disruption and
environmental impact
UPPAL casting yard is at higher progress and also the
largest yard.

station viaduct (6)
13. COMPONENTS OF MOULDS:
Each mould consists of
Soffit assembly
External side shutter assembly with supporting truss
(left/right)
Inner assembly
Bulk head panel
Working platform and access stair case
14. 3.3 SEGMENT CASTING:
The casting procedure for the pier heads is done first and then
followed by the intermediate segments.
Mould set -up
Reinforcement
Sheathing and Duct profiling
Concreting
Initial settlement
De-shuttering
Curing
15. MOULD SET-UP :
The leveling of the form work at soffit and supports are provided for
mould. Then the external form work (outer assembly) of pier segment is
closed.
REINFORCEMENT:
The reinforcement is done to the segment in order to increase the strength
of the segment. For the reinforcement to be carried out as
a) Selection of suitable Reinforcement bars
b) Cutting and bending of Reinforcement
c) Placing of Reinforcement
16. SHEATHING AND DUCT PROFILING :
As post tensioning is to be done for segment after casting, the profiling of
ducts is done through the sheathing by using HDPE Single Wall Corrugated
(SWC) Sheeting Ducts.
Duct profiling is to be done to provide the ducts to segments at specified
coordinates in order to insert the cable into ducts and connect to the
intermediate as well as pier heads.
CONCRETING :
The placing of concrete is normally done by boom placer /concrete pump/
crane bucket. While inserting the vibrator, care should be taken that it does
not disturb sheathing. Concreting should be started from bottom slab, and then
moved to the web. In web portion, it is done layer by layer. On completing the
web portion pouring of concrete should be at top portion. The concreting is
done starting from two ends moving towards the center. At last, central part of
top slab is concreted.
17.
18. INITIAL SETTLEMENT :
After the concreting, before demoulding of the segments, the fresh finished
concrete is to be settled and top surface shall be cured by covering with
hessian cloth and dampening by regular sprinkling of water. The process
should be done until the casted segment attains strength of 20 MPa and after
that the segment should be match to other segment.
DE-SHUTTERING :
After attaining the strength of 20 to 25 MPa, the mould is to be de-shuttered by
suitable machinery by intense care without disturbing the casted segment. The
segments are to be numbered to match cast with other segments and date of
casting is to be written on segment for curing process.
CURING :
The segments are to be transported to the casting bay and placed there for a
period of 14 days from the date of casting and continuously cured by dedicated
curing workmen with water sprinklers or pumps fitted with flexible pipes in
each curing bay.
19.
20. 4. CONSTRUCTION PHASE-1
SAFETY BARRICATION :
EXCAVATIONS :
Excavation for structures should be done by removing material on the
planned location as per markings and dimension as shown in the GFC
drawing
Excavation shall be done with (300-400mm) working space on both side
along the width at bottom of foundation.
Slope shall be maintained on either side along the longitudinal direction
of the alignment.
21. MARKING FOR FOUNDATION :
After the excavation has been done to the required depth as indicated in the
drawing, the geologist will inspect the foundation and will co-relate with
the data observed during the confirmatory bores with the actual strata
observed at site and shall confirm the foundation.
Marking of foundation for tying reinforcement, shuttering shall be done as
per coordinates given in GFC drawings.
Outlines of the foundation Centre of pier location on PCC shall be drawn
using red oxide powder and cotton thread, before laying the reinforcement.
REINFORCEMENT FOR FOOTING AND PIER :
22.
23. SHUTTERING :
Prefabricated steel formwork shall be used.
Shutter shall be dry and free from foreign materials before applying
approved release agent.
Surface shall be coated with mould releasing agent using brush to prevent
adhesion of concrete to the formwork before fixing of shutters.
Shifting and placing of shutters shall be done manually or with the help of a
crane.
24. CONCRETING :
The M35 grade concrete shall be used. Temperature shall be checked for
every transit mixer before unloading.
Pouring of concrete shall be done either by hose attached to concrete
delivery pumps or by portable G.I chute directly from the transit mixer,
depending on the ground situation.
The concrete mix is designed keeping in view the hot weather of
Hyderabad. The temperature of concrete shall not exceed 30 degree
centigrade.
In hot weather adequate manpower shall be available to quickly place,
finish and cure the concrete.
CURING :
Curing of concrete shall start immediately after the concrete has attained the
final setting time. It shall be carried out by spreading hessian cloth and
sprinkling water at regular intervals.
Wet curing shall be done for 15 days
26. 5. CONSTRUCTION PHASE-2
LAUNCHING GIRDER ERECTION :
The LG consists of different boxes for holding the segments .A LG in
HMR project generally consists of 8 boxes and each box length varies
from 6 to 10 meters. It is provided with 4 supports.
1. Front support
2. Middle support
3 .Rear support
4. Rear trolley
27. LAUNCHING GIRDER ASSEMBLY:
Erection of the launching girder is a difficult part in the whole process of the
work. Placing the rear support on the pier. A suitable weight of 6* 11 tonnes
blocks are placed on the rear support as it acts as a cantilever. Then suitably
placing the middle and front support with the help of form work and piers
respectively. The launching girder which is completely assembled at the yard is
erected so that it is resting on the pier heads between the two piers.
28. SEGMENT ERECTION AND ALIGNMENT :
The launching girder has got 11-12 wires which are connected to the segment for
the purpose of lifting. After connecting the segments, they should be able to be
held without the help of launching girder. For this purpose post tensioning is done.
POST-TENSIONING:
This is the method of providing reinforcement with high strength steel strands
or cables, typically known as tendons. Post-tensioning tendons are considered
"active" reinforcing.
The tendons, like rubber bands, want to return to their original length but are
prevented from doing so by the anchorages.
The cables are inserted through every notch present in each segment (generally
three notches are present) and these are anchoraged at the piers.
29. GLUING:
The required quantity of epoxy shall be brought from the cold storage unit at site.
The epoxy shall be mixed with a properly sized mechanical mixer operating at not
more than 600 to 800 rpm and/or in accordance with the recommendations of the
epoxy manufacturer.
Epoxy mixing shall be started only after the segments to be joined are within
approximately 300mm gap of their final position. The mixing time of epoxy each
batch shall be maintained so that the material of each batch is applied to the face of a
joint within a maximum of 45 minutes. The epoxy shall be uniformly applied in
accordance with the manufacturer’s recommendations by spatula or gloved
hand a nominal thickness of 1.5 mm or to the one face 2mm thickness.
