Last eight years we have been working in Dam instrumentation and provided
solutions to old problems of data collection, sensors’ diagnosis and read out,
Digitizing of Inclination/ deflection meter, retrieving uplift pressure cells ,VPD
Reopening with special machines ,underwater video shooting , dam gallery
low voltage safe lighting systems , upgradation of seismic instruments etc.
We have also delivered lecturers for Meri and the similar institutes for guidelines

Choking up of Vertical Porous Drain Pipes (VPD)
Innovative Methods Adopted to Tackle
Above Problems:-
•
•
It is observed that in downward
drilling process the new hole
does not match with the original
VPD and does not open out in
the gallery, instead travels in the
walls of the gallery further
defeating the very purpose.
So Vertically Upward Drilling
from the gallery of the dam
towards the top of the dam has
been adopted. The work is
carried out with powerful
hydraulic machines designed to
fit in the gallery. It can drill upto
75m in the upward direction and
maintain verticality.

Non-functioning of Drain holes in the Foundation Gallery





Reasons:Drain holes are drilled at a certain
inclination, due to which cleaning of leaching
material / grout material is not possible.
High power machinery for deep holes cannot
be used for inclined drilling due to restricted
space in Gallery.
Problems Arising :
Uplift pressures are induced on the base of
the dam which can lead to problems tot he
safety of the dam structure.
Innovative Methods Adopted to Tackle
Above Problems:An Innovative method has been devised for
cleaning of Drain Holes.
Flexible shafts rotating at very high speeds
with special cutting tools and a movable
trolley are used for the above mentioned
work. The machine can drill at any inclination
and in a very restricted area of working.

Non-Functioning of Uplift Pressure Cells


Innovative Methods Adopted to Tackle Above Problems:An Innovative method has been devised for cleaning of the Uplift Pressure
Cell Pipes which are very small in diameter and which have 90 degree
elbows.
A high pressure compressed air along with special chemicals is pumped in
the pipes and a system is kept for flushing. This dissolves the blocked
material. Pipes are internally cleaned for normal operations.
Till date this is the only successful method employed.
Choking up of Gravity Drain Pipes
•
•
•
•
•
Reasons:Grout Material Travelling inside Gravity
Drain Pipes
Due to Leaching action of the dissolved
Calcium and Salts in the water.
Problems Arising :
flooding of Drainage Galleries
Burning up of VT Pumps & Submersible
Pumps.
Non-Access
to
Gallery
for
any
Maintenance Job.

Leaching Material
Innovative Methods Adopted to Tackle
Above Problems:•
An Innovative method has been devised for
cleaning of Gravity Drain Pipes. A high speed
portable and heavy duty drilling machine has
been designed for drilling in horizontal and
inclined directions. Machine can be mounted
on raised platforms. Further chemicals are
introduced for making the inner surface of the
pipe smooth so that further accumulation of
leaching material can be arrested
