This 3-sentence summary provides the key details about the industrial training report: The report discusses MD. Shadab's 10-day industrial training at Delhi Metro Rail Corporation from July 10th to August 10th, where he learned about tunnel construction, safety protocols, waterproofing techniques, and concrete work methods used in metro tunneling projects. Key aspects covered included the use of TBMs to construct twin tunnels over 5 meters in diameter, safety equipment like helmets and gloves, applying waterproofing membranes, and placing and curing concrete for tunnel infrastructure.

5. TUNNELOVERVIEW
KEY POINTS ABOUTTUNNEL:-
 Tunnels are constructed with the help of TBM (tunnel BoringMachine)
 The type of tunnel is “twin tunnel”.
 Inner diameter of tunnel is 5.8m
 Outer diameter is 6.5m
 There are 6 segment key in one ring of thickness 275mm and length 1.4m
 A cross passage is provided after every 200 rings for emergency exit.
 The lower most of the tunnel is 20m below the groundsurface.

6. TBM (Tunnel Boring Machine)
A tunnel Boring machine also known as “mole“, is a machine used to
excavate tunnels with a circular cross section through a variety of soil
and rock strata. They can bore through anything from hard rock to
sand. Tunnel diameter can range from a meter (done with micro-TBM)
to 19.25 meter to date.
Tunnel boring machine are used as an alternative to drilling and
blasting methods in rock and conventional “hand mining “in soil. TBM
have the advantages of limiting the disturbance to the surrounding
ground and produced a smooth tunnel wall.
The major disadvantage is the upfront cost. TBMs are expensive to
construct, and can be difficult to transport. However, as
modern tunnels become longer, the cost of tunnel boring machines
versus drill and blast is actually less.

8. WATER PROOFING
Waterproofing is the creation of a relatively impervious
membrane, coating, or sealer used in concealed locations to
prevent water from entering or passing through either
horizontal or vertical building materials.
Chemicals used for Waterproofing
-For Priming Purpose
Master Seal M2525(Provided In two component A &
B)
-Waterproofing Layer
Master Seal M800(Provided In two component A &
B)
Master Seal M2525-Master Emaco 2525 is a solvent
free, high-performance, versatile epoxy binder
that can be used to produce a range of epoxy resin
based mortars.
