Construction of tunnels comes with many complex civil Engineering problems.
The typical reinforced-concrete diaphragm called slurry wall is used in
underground constructions like mines. When it comes to the construction of
slurry walls, proper care should be taken as there are chances for these walls
to collapse during construction. Most of the construction professionals come up
with such kinds of complex civil engineering problems during underground
construction works. Just keep reading on the article to know more about the 3
common civil engineering problems and their solutions.
1. The Slurry walls
The main purpose of the slurry wall is to prevent or redirect the flow of
ground water. These slurry walls are indispensable for underground
constructions near hazardous waste dumping sites. For example, the construction
of dams may be near to the hazardous waste dumping sites and hence it
is necessary to effectively stop the flow of contaminated water to
the dam water. Most of the construction experts face complicated problems while
constructing slurry walls. Once of the main problems is that these slurry walls
will easily collapse if not properly built. The durability of a slurry wall
great depends upon the mixing of slurry. All the difficulties involved in the
construction of slurry walls could be overcome by the use of modern special
equipments for the construction of tunnels.
2. Ground Improvement
Compact soil is very much essential for strong building
foundations. However the nature of soil will vary from place to place.
Hence it is necessary to do some processing for making the soil compact before
the construction work is started. Today, with the advancements in technology,
several ground improvement techniques are available. Deep soil mixing is the
best solution for compacting soil. Though there are several other ground
improvement techniques, no other technique is as effective as deep soil mixing.
The soil becomes as compact as concrete after deep soil mixing. This provides
great support to the foundation of buildings. Deep soil mixing is done by
pumping the Binder into the soil and simultaneously mixing the binder and soil
with a device normally mounted on an excavator. The most commonly used binders for
deep soil mixing are Lime/Quick Lime, Fly ash and Sludge.
3. French drain to redirect ground water
Ground water can be harmful to a building if it penetrates the basements.
The building will even collapse if the ground water is allowed to flow into the
basement for a prolonged period. Hence ground water redirection is very much
important for effective construction. The French drain is one of the best
options available for redirection of ground water. The French drains have the
capability of relieving ground water pressure near the retaining walls.
Bottom Line
The civil engineering problems related to construction are very complicated.
Hence it is always good to seek professional assistance from some construction
experts.
