KNOW ABOUT UNDERGROUND BORING

 Underground boring is a method of installing underground utilities without damaging the
surface of the earth. Underground utilities such as pipe, cables etc are inserted underground
as a part of modern infrastructure. Underground boring is very useful for installation of
infrastructure such as telecom, water lines, power cable, gas lines, oil lines etc. This article
explains different methods, equipment and techniques related to underground boring.
Industrial drilling involves trenchless drilling which does not disrupt the existing structure.
What are the Steps to Follow:
 The process begins by drilling a hole in the ground. The experts make a route drilling
based on the direction of the pipeline.
 The hole must be spacious enough to fit the pipe well. That’s why the whole needs
to be enlarged.
 In the last step the installation of the pipe occurs.

 

Benefits of Underground Boring Services:
 Underground boring is more effective and environment friendly than conventional
drilling methods. Underground boring does not create road blockades or other
hazardous situation.
 Underground drilling does not responsible for soil disturbance.
 If the drilling is performed into any water body, the contamination is very less. That
is why Underground drilling is safer.
 It is an efficient method because the work schedule remains the same even if there’s
weather disruption.
 If someone wants to repair the home sewer lines, underground drilling is the best
method to follow.
 Trenchless underground boring is effective when contractors deal with industrial
project or any project an in the urban areas.
Common Types of Underground Boring:
There are different methods of underground boring that are being used based on the
project. Two most popular methods are:
 Directional Drilling
 Auger Boring.

1. Directional Drilling: Directional boring or directional drilling is also popular as
horizontal directional drilling. It is a trenchless method. It is a safer process that is
used in places where the surface disturbance must be minimal and where the

trenching could not be used. The term directional boring is mainly used for small
drilling rigs whereas the HDD is used for giant drilling rigs. For this kind of
underground boring, various pipes can be used e.g. PVC, ductile iron, polyethylene,
steel and polypropylene. This method is suitable for variety of soil conditions which
includes clay, sand, rock, and slit. There are three factors that determine the
equipment used for the directional drilling process-
 Crossing length.
 The surface conditions.
 The properties of the pipelines used.

Directional boring is used in different fields. The usage area includes: crossing waterways,
congested areas, roadways, areas where other methods are costly, shore approaches,
environmentally sensitive area. This method is beneficial in many ways:
 The process is environment friendly.
 It is good for less traffic disruption.
 Directional boring takes shorter time to complete.
 The cost is less.
 It provides deeper and longer installation.
 It does not have any access pit.
 It has directional capabilities which makes directional boring more acceptable.
In directional boring, three types of locating equipment are used for locating the bore head:

 Walk-over locating system.
 Wire-line locating system.
 Gyro-based locating system.

Among these three, any one method is chosen based on the site requirements.
2. Augur Boring: Augur boring forms horizontal bore by installing a steel casing through
the surface of the earth from a main shaft to a reception shaft. Even if it is a well
established and cost effective method but it has one drawback. It is not appropriate
in terms of accuracy constraints. It has few benefits which include:
 It is a simple and effective procedure with high success rates.
 A fast method and has low operating cost.
 The procedure is safer.
 Augur boring creates very stable bores.
 Very little disruption in the earth surface.

How Does the Process Begins:
Before starting the drilling process, the experts need to keep few things in mind to run a
smooth and trouble free boring. As it is their duty to conclude the job efficiently, they need
to decide which method will be more useful.
The first action is to understand the area well and to choose proper tools and methods for
the area. To prevent any mishaps, it is very important to ensure that area does not have any
existing utilities. If it has any, the experts team need to change their route.
As the drilling begins, the drill operators need to dig out underground hole. Through this
hole, mud is pump bored. This process is only applicable for directional boring. In case of
Augur boring, the metal piping does the work.
It is always recommended to look for experts or contact companies who provide such
services to avoid all kind of mishaps.
