Construction of tunnels

Construction work at many times can be quite challenging and it can
be not everybody’s cup of tea. This means that the construction
companies that are into building high rises may not find themselves
comfortable with building dams or tunnels. They may have their
expertise in one genre of the business and it definitely does not
mean that they can’t try something else in the same industry but
for projects that require experts to work, it is recommended that
companies should stick to their genre of business and not move into
the other genre. However, if they still want to try then they need
to first gather enough details about the kind of work and also
possess the required equipment to execute the project. Construction
of tunnels is one such job that requires an expert to deal with.
Companies dealing with construction work other than building
tunnels may not understand how to begin and where to end the work.
Therefore it makes sense for construction companies that have been
dealing with construction of tunnels to dig their heads into it and
execute the work with finesse. Investigating the land is
important:- Investigating the ground condition is quite crucial to
start with a major tunnel project. The company should first collect
samples from boreholes by adopting geophysical techniques. Once
that is done and everything seems to be ok, you can start with the
excavation work. Now the investigation part is crucial because it
will help the experts to foresee any possible dangers that might
erupt once the construction work begins. Availability of heavy
equipment:- Heavy equipment play a significant role during the
entire process of construction of a tunnel. The company needs to
have the best machine in place and also the best operator to
control the machines. Now when we talk about heavy equipment, the
most crucial is excavator. When you go about to construct a tunnel,
you need to excavate the ground and rock to pave way. This work can
be really dangerous if not done correctly and the operator needs to
be very cautious when he is working on such a complex project. An
experienced operator should be given the task to excavate the rock.
Try not to involve a newbie in it. Once a way is paved the latter
part of the excavation can be given to less experienced operators.
Heavy equipment that are used in the project should meet
international standards. Anything less than that can pose a risk to
the lives of many involved in the project. Groundwater control
should be maintained:- It is very crucial to maintain groundwater
control. Any sort of water leaking or vertical shaft can largely
reduce the stand-up time. This can lead to a risk of collapse if
not checked in time. One can avoid the risk by installing
dewatering pipes and pump the water out. Another technology that
can be used is ground freezing. Ground freezing is an expensive
option but quite effective. It freezes the ground and the soil
surrounding the excavation until a permanent structure is built.
