Summary Draft #2
Summary (Part 1):
Tunnels
in the past were utilized for purposes such as irrigation, drainage, and water
transportation system as well as communication routes to ameliorate the
underground habitats. A Leonard (2022) article titled, “Innovation at the end
of the tunnel”, informs readers about the rising need for underground
infrastructure brought on population pressure and urbanization. This
underground infrastructure includes functions such as sanitation, logistics,
and transportation. To meet these demands, modern tunnel-boring machines were
introduced to meet these needs. As mentioned in another webpage by
Trenchlesspedia, (2020, para. 2), tunnel-boring machines are referred to as
“mole(s)” and are designed to bore circular tunnels through all types of earth,
from sandy soil to hard rocks. With an increase in usage, tunnel-boring
technologies are thriving in today's construction sector. The recently completed
construction of the Thomson - East Coast Line (TEL) in Singapore is an excellent
example of how this technology being extensively utilized(Wong, 2019). Modern tunnel-boring
technology prevails over traditional tunnelling methodologies, such as drilling
and blasting. This is because, despite its high initial cost, it is superior in
terms of building efficiency and operational safety
