The Ultimate Guide to Tunnel Excavation
2
Introduction
For urban development, a tunnel excavator is
essential. These machines have been in operation
for a long time, and they have provided us with
everything from minor pipelines to mineral
excavation to the world's largest underground
rail tunnel. As you know, excavators are a common
sight in a construction project, depending on the
job, but the attachments will vary as per the
requirement in the job site. Today, I will
discuss one of the attachments which are common
in tunnel making, i.e, the tunnel excavator and
other machinery which are used for tunnel
excavation.

What Is Tunnel Excavator?
A tunnel excavator provides a tailored tunnel
excavation solution. The excavators have a short
boom with a small tail swing radius, allowing
them to work successfully in tight spaces. The
hydraulic tunnel excavator is equipped with a
high-efficiency hydraulic system that works in
fast-paced mixed situations. To get the most out
of your investment, you should look at excavators
for sale.Apart from the tunnel excavator, the
following are the most commonly used tunnel
excavation machines.

Tunnel Boring Machine
On highways, tunnels are built in three different
shapes circular, rectangular, and horseshoe. The
tunnel's shape is determined by the method of
construction and the utilisation of machinery.
Tunnel boring machines (TBM), drills, and rock
blasting are used to excavate. These are modern
excavators that are designed to dig or grade and
assist in the movement of huge boulders and other
objects during excavation. These crawlers are
propelled by a rotatory wheel system that allows
them to dig, pick, and transport massive, heavy
items. It moves in a different direction for
cross-section tunnel digging thanks to its
components such as crawler chassis, rotor
support, central swivel joints, and motor
support. These excavators are designed to be
simple to operate.

Horizontal Directional Drilling Machine
The machine can be used for trenchless drilling
to install pipes and pipes underground or in
shallow arcs. The drilling machines are available
in a variety of sizes, with the largest
horizontal directional drilling machine capable
of drilling up to 200ft and 6000ft in length. It
digs tunnels along roads or waterways to install
PVC, ductile iron, steel, polypropylene, and
other pipes.

Conclusion
Tunnel excavation is a multi-equipment task. It
is always a good idea to have a better
understanding of the tunnel excavation equipment
available. Road tunnel planning requires
multidisciplinary involvement and assessment,
which starts with acquiring a high-quality tunnel
excavator. Buy a tunnel excavator for sale to
relieve operational challenges in tunnel
construction.
