17 and inserting the connecting pins 19 into the aligned holes 31 39 the piling sections 63 are cylindrical and have an outer diameter less than the distance between the two latching bars 15 the hydraulic ram 41 is placed between the reacting bar 17 and the driving plate 21 to install a column of piling sections 63 hydraulic power is supplied to extend the ram 41 as shown in fig6 the ram 41 applies a downward force to the driving plate 21 as the reacting bar 17 opposes the upward reaction force this upward force is directed into the slab 53 and beam 59 by the driving assembly 11 and tends to lift the foundation the downward force pushes the piling section 63 into the earth 55 once the ram 41 is fully extended the ram 41 is retracted and removed and the driving plate 21 is then removed a second piling section 63 is placed in the anchoring cylinder 13 the driving plate 21 is replaced and the ram 41 is reinserted the second piling section 63 is then driven into the earth 55 and the process is repeated until the earth 55 below the piling sections 63 is compacted enough to resist further downward movement the top of the driving plate 21 must.
