Piling Work for 24 inch Pile
a. Survey team determine location of piles appropriate to drawing.
b. Put the piles at piling position points which have been determined of survey team.
c. Using a Total Station for check piling position from two directions mutually perpendicular to ensure no deviations and piling has perpendicular at a supposed.
d. Piling can be started, put drop hammer / hydraulic hammer above the piling and monitor immediately with both Total Station to the position of piles fixed perpendicularly during piling process.
e. Stop piling if pile has arrived at a depth of planned or arrive at the layer of soil / hard rock.
Installation Sheet pile
a. Installation of guide beam to set out the position of the sheet pile wall.
b. Install sheet pile, the crane lifts up the first sheet pile and drives it into the ground, leaving about 2 meter length of the sheet pile above the ground level.
c. Install the second sheet pile into the ground and the second sheet pile interlocks with the first sheet pile.
d. Process b and c repeats till the installation of sheet piles is completed within the length of the guide beam.
