METHOD STATEMENT FOR INSTALLATION OF SHEET
PILES
The following major items of Plant and Equipment are required
for the installation of
sheet piles.
i. 65 Ton Crawler mounted crane
ii. 50 90 Ton Vibratory Hammer w/power pack.
iii. BSP Type Pneumatic Pile driving hammer
w/compressor and suitable lead.
iv. Total Station for surveying.
v. Suitable pitching frame / leader.
The first step in the construction of a sheet pile wall is the
installation of the pitching
frame. This is required to ensure the verticality and alignment
of the piles during their
driving. The pitching frame is installed with accuracy using
appropriate surveying tools.
The installation of the pitching frame is done in the same
alignment as the sheet pile wall
to be installed.
Once the pitching frame is in place 10-12 sheet piles are
pitched in it. The crawler
crane is used for handling and pitching of the sheet piles. The
piles are joined together
by placing the thumb of one pile into the fingers of the
previously placed piles. After a set
of piles has been joined the driving hammer is used to drive the
pitched piles to approx.
1/3 of their length. Then the next set of piles are
pitched/joined and driven to a depth at

which resistance is encountered. In this way the last (and
partly driven) pile of the
previous set serves as the guide pile for the next panel. Thus
enabling us to pitch the
rest of the piles without the use of the pitching frame. However
if it is necessary the
pitching frame can be extended for each subsequent set of piles.
We then go back
to the initial set of piles and drive them further. This
procedure is repeated till all the
piles are driven to the required depth. Throughout this whole
operation the
verticality and alignment of the piles will be checked
periodically with the use of a plumb
line and surveying instruments.
