FLEXIBLE CENTER PLUGS FOR DIEDRICH CUTTER HEAD

  THIS NEW INNOVATION ALLOWS THE USE OF HOLLOW STEM AUGERS FOR DRILLING THROUGH WATER BEARING SANDS WITHOUT TROUBLESOME "BLOW-IN" OR "HEAVE".

   Fitting into the specially machined slot in the DIEDRICH CUTTER HEAD, the plug prevents water bearing sands from entering the hollow stem auger while drilling or split spoon sampling. The plug eliminates the need for water and/or drilling mud or cleaning material out of the bottom of the auger while drilling.

  The Flexible Plug is available in four sizes:

Q-350   3-1/4 ID        

Q-351   4-1/4 ID      

Q-353   2-1/4 ID         

Q-352   6-1/4 ID

FLEX PLUG OPENER

aug5.jpg (50206 bytes) You can now set your water monitoring wells using the Diedrich Hollow Stem Augers and the Diedrich Flex Plugs (pat no. 4667,754)

   The hole is augered to the total depth of the well using the hollow stem augers equipped with the flex plug. The flex plug also allows sampling of the water bearing sands during the drilling operations.

   A flex plug opener consists of an AW rod connection to a flat steel plate that is held into a thin wall piece of steel tubing by an "O" ring. This thin wall steel tubing is approximately the length of the flex plug with the fingers removed.

   The AW rod with flex plug opener is lowered to the flex plug location in the auger head and pushed into the flex plug, opening up the fingers of the flex plug catch on the bottom of the opener tube preventing it from coming back out of the hole when the AW rod and plate are removed from the auger string.

   The center hole of the auger is now ready for the insertion of the well screen and riser. This well can be constructed in the usual manner and the flex plug and opener tube can be removed when the augers are removed from the hole.
