Construction Techniques used for delhi metro project

Methods of tunneling in Delhi Metro is vary with the nature of the material

to be cut through. When soft earth is encountered, the excavation is

timbered for support as the work advances; the timbers are sometimes left

as a permanent lining for the tunnel. Another method is to cut two parallel

excavations in which the side walls are constructed first. Arches

connecting them are then built as the material between them is extracted.

Portions of the unexcavated center, left temporarily for support, may be

removed later. A tunnel cut through rock frequently requires no lining.

Hard rock is removed by blasting.

Workers generally use two basic techniques to advance a tunnel. In the full-

face method, they excavate the entire diameter of the tunnel at the same

time. This is most suitable for tunnels passing through strong ground or

for building smaller tunnels. The second technique, shown in the diagram

below, is the top-heading-and-bench method. In this technique, workers dig

a smaller tunnel known as a heading. Once the top heading has advanced some

distance into the rock, workers begin excavating immediately below the

floor of the top heading; this is abench. One advantage of the top-heading-

and-bench method is that engineers can use the heading tunnel to gauge the

stability of the rock before moving forward with the project.

Soft Ground (Earth)

Workers dig soft-ground tunnels through clay, silt, sand, gravel or mud. In

this type of tunnel, stand-up time -- how long the ground will safely stand

by itself at the point of excavation -- is of paramount importance. Because

stand-up time is generally short when tunneling through soft ground, cave-

ins are a constant threat. To prevent this from happening, engineers use a

special piece of equipment called a shield. A shield is an iron or steel

cylinder literally pushed into the soft soil. It carves a perfectly round

hole and supports the surrounding earth while workers remove debris and

install a permanent lining made of cast iron or precast concrete. When the

workers complete a section, jacks push the shield forward and they repeat

the process.

Marc Isambard Brunel, a French engineer, invented the first tunnel shield

in 1825 to excavate the Thames Tunnel in London, England. Brunel's shield

comprised 12 connected frames, protected on the top and sides by heavy

plates called staves. He divided each frame into three workspaces,

or cells, where diggers could work safely. A wall of short timbers,

or breasting boards, separated each cell from the face of the tunnel. A

digger would remove a breasting board, carve out three or four inches of

clay and replace the board. When all of the diggers in all of the cells had

completed this process on one section, powerful screw jacks pushed the

shield forward.

Hard Rock

Tunneling through hard rock almost always involves blasting. Workers use a

scaffold, called a jumbo, to place explosives quickly and safely. The jumbo

moves to the face of the tunnel, and drills mounted to the jumbo make

several holes in the rock. The depth of the holes can vary depending on the

type of rock, but a typical hole is about 10 feet deep and only a few

inches in diameter. Next, workers pack explosives into the holes, evacuate

the tunnel and detonate the charges. After vacuuming out the noxious fumes

created during the explosion, workers can enter and begin carrying out the

debris, known as muck, using carts. Then they repeat the process, which

advances the tunnel slowly through the rock.

key qualifications:

I have over 18-years experience in Structural analysis Through STAAD-PRO

and rebar detailing (specialized in detailed shop drawings of reinforced

Rebar drawings with manual calculation and software like CADS RC, LOHA).

Leading my design team to preparing workshop drawings based on Design

principle of reinforcement drawings issued by designers. As well as, good

supervision ability to construction related issues. Controlling and

distributing all shop Drawings timely to Construction teams. As per the

fast track construction Schedule, preparing all Rebar detailed drawings and

Bar Bending Schedules for various types of Reinforced Concrete and Pre-

stressed Concrete structures. The structures include Bridges, Museum,

Flyovers, underground structures, such as tunnels and metro stations,

various residential and high rises, Factory / Industrial buildings & Power

Plants.

I have knowledge of the latest Codes and design specifications for the

preparation of reinforcement details and bar bending schedules, such as

British, American and Indian Standards. I am competent to use software such

as MS Excel, ACAD and CADRC for the preparation of estimates and

reinforcement bar details.

I have worked in design offices, sites and also as freelance consultant.

This has enabled me to be an effective communicator and meticulous and

diligent worker capable of meeting tight deadlines on complicated projects.

My exposure to studying various structures has provided me a capability to

visualize arrangement of structures and also layout of reinforcement in

complex arrangements. During various assignments I have also been team

leader and checker.
