Setting Up Of The Piling Rig At A Pile Position


Purpose & Scope

This procedure details the procedure for setting up the piling rig at a pile position,

and ensures that the rig is set up accurately and correctly. The procedure considers:

Setting up over a pile position marked by a setting out pin.

Setting up over a pile position marked by a scalloped guide wall.

Setting up in special situations different from above e.g. over water.

Procedures

Step 1 /4


Setting up over a pile position marked by a setting out pin

 

Track the piling rig into a position where it can bore the pile with the tracks flat and level, ensure the upper and lower works are symmetrical, this will ease adjustments to Casing position later if required.

 

 Ensure that the spoil can be removed using an excavator from the operators side and an exclusion zone can be established.

 

Position the auger approximately over the setting out pin

(FIG 01).

Procedures

Step 2 /4


The mast is adjusted to a vertical orientation, both front to back and side to side, using the levels attached to the mast or a spirit level (FIG 02 & FIG 03).

 

The auger is repositioned more accurately over the setting out pin using a combination of tracking and slewing (FIG 04).

 

Repeat previous steps as necessary.

Procedures

Step 3 /4


Set up a sighting bar at right angles to the pile position measure out reference pins that will be used as positional checks during the Casing installation (FIG 05).

 

When the auger is accurately positioned (with a vertical mast) a final check is made by rotating the auger. Slew the rig off to the side at least two times ensuring the machine is not rocking.

 

Complete a final verticality check prior to commencing boring.

 

Pile construction can commence

 

Record the pile number and time on the digging and concrete sheet

Procedures

Step 4 /4


Setting up over a pile position marked by a scalloped guide wall (FIG 06 & FIG 07).

Track the piling rig into a position where it can bore the pile with the tracks flat and level, ensure the upper and lower works are symmetrical, this will ease adjustments to Casing position later if required.

 

Ensure that the spoil can be removed using an excavator from the operators side and an exclusion zone can be established.

 

Position the auger approximately over guide wall position.

 

The mast is adjusted to a vertical orientation, both front to back and side to side, using the levels attached to the mast or a spirit level. The auger is repositioned more accurately over the guide wall using a combination of tracking and slewing. Repeat steps previous steps as necessary.

 

Set up a sighting bar (MP5000 only)

When the auger is accurately positioned with a vertical mast a final check is made by rotating the auger. Slew the rig off to the side at least two times ensuring the machine is not rocking.

 

Complete a final verticality check prior to commencing boring and pile construction can commence and record the pile number and time of commencing boring in the Banksmans book.

 

Setting up in special situations different from above e.g. over water.

Special set up of the piling rig pile position over water will follow a similar procedure to that detailed above however this may involve procedures such as setting up over a guide frame or from setting out instruments. These situations will be dealt with by a separate procedure that is specific to the particular situation.
