THE START OF BORING UNDER DRIVEWAYS AND ACROSS STREETS

THE BORING OF THE 6" STREET NEW WATER PIPE UNDER DRIVEWAYS BEGAN TODAY.  "KEN CABANA" OF CABANA  CONST. WILL  PROVIDE  THE MACHINERY. DRIVE WAYS THAT ARE PLAIN  CONCRETE WILL BE CUT, BORING WILL BE UNDER PAVER DRIVES OR CUSTOM STAMPED DRIVES.

"JERRY NELSON"  RUNS THE BORING MACHINE, THAT USES 10' RODS, CONNECTED END TO END,  TO PUSH A HEAD THROUGH THE GROUND. THIS HEAD HAS A BLADE WITH A 7 DEGREE ANGLE TO CONTROL THE DIRECTION OF THE BORE.

A SOLUTION OF BENTONITE DRILLING CLAY AND WATER IS PUMPED THROUGH THE DRILLING PIPE AND HEAD TO FORM A SMOOTH HOLE BEHIND THE HEAD..

 "RICK NELSON", FOLLOWS THE HEAD ELECTRONICALLY AND BRINGS THE HEAD TO THE SURFACE AT A PREDETERMINED POINT.

THE BORING HEAD IS REMOVED AND A 12" DRILLING HEAD IS ATTACHED.

THE 6" SIDE STREET NEW WATER PIPE IS LAID OUT . A 6" STEEL BELL IS SLIPPED OVER THE 6" PVC,  DRILLED AND BOLTED IN PLACE AND ATTACHED TO  THE 12" DRILLING HEAD.

THIS 6" PVC PIPE IS THE SAME AS THE 6" PVC PIPE THAT WILL BE PLACED INTO THE DITCH, EXCEPT THIS PIPE HAS A SPECIAL GASKET THAT PREVENTS IT FROM PULLING APART WHILE BEING PULLED THROUGH A BORED HOLE.

THE PIPES ARE LUBED AND SLIPPED TOGETHER

THE BORING MACHINE BEGINS TO PULL THE 12" DRILLING HEAD AND THE PVC BACK THROUGH THE HOLE. AS IT DOES, WET CLAY IS PUMPED THROUGH THE HEAD TO FORM A POOL OF MUD TO ALLOW THE 6" PIPE TO FLOAT BEHIND IT. A VACUUM PUMP IS USED TO SUCK UP THE EXCESS MUD AS IT COMES THE

SURFACE..

 

AS THE PIPE  DISAPPEARS INTO THE GROUND THE OTHER END APPROACHES THE BORING MACHINE. THE HEAD COMES SPINNING OUT. SUCCESS..A JOB WELL DONE.

MEANWHILE THE WATER PIPE CREW HAS HAD A MORE THAN SUCCESSFUL COMPACTION TEST AND WILL LAY THE ASPHALT TOMORROW.

THEY INSTALLED THE 12" PIPE CONNECTIONS ON BOTH SIDES OF THE HIGHWAY. ON THE WEST SIDE A CANON FLUSHING PIPE IS TEMPORALLY INSTALLED TO ACCOMMODATE THE FLUSHING OF THIS PORTION OF THE PIPE.
