JACK PUSHING R.C.C PIPE (MS COLLER)

A JACKING PIPE IS A HIGH COMPRESSIVE STRENGTH PIPE THAT IS JACKED INTO THE EARTH USING THE PIPE JACKING TECHNIQUE . THE PIPES ARE JACKED THROUGH THE SOIL BY USING HYDRAULIC JACKS THAT DRIVE THE SHIELD AT THE FRONT OF THE PIPE STRING . PIPE JACKING IS A TRENCHLESS CONSTRUCTION METHOD THAT IS CARRIED OUT FROM A LAUNCHP IT POSITIONED AT THE DEPTH AT WHICH THE PIPE IS TO BE INSTALLED . THE METHOD IS VERY USEFUL WHEN PIPELINE INSTALLATION HAS TO BE CARRIED OUT IN PLACES WHERE SURFACE DISRUPTION IS TO BE MINIMIZED SUCH AS UNDER ROADWAYS , HIGHWAYS , RUNWAYS AND RAILWAYS .

TRENCHLESS PEDIA EXPLAINS JACKING PIPE

MICROTUNNELING AND PIPE JACKING ARE TWO OF THE METHODS OFTRENCHLESS CONSTRUCTION THAT UTILIZE JACKING PIPES . THE PROCESS INVOLVES DIGGING A LAUNCH SHAFT FOR PLACING THE REQUIRED MACHINERY AND EQUIPMENT THAT WILL DRIVE THE PIPEINSIDE THE SOIL . ALSO KNOWN AS THRUST PIT , A THRUST WALL ISINSTALLED AT THE BACK OF THE PIT TO GAIN THE REQUIRED THRUST FOR THE JACK TO PUSH THE PIPE POSITIONED BEHIND ASHIELD . AS THE DIGGING PROCEEDS THE PIPES ARE PUSHED IN BEHINDAS A STRING . THE INSTALLED PIPE IS WATERTIGHT AND STRUCTURALLY SOUND WITH FLEXIBLE GASKETED JOINTS . THE RECEIVING SHAFT AT THE OTHER END ALLOWS THE SHIELD TO BERETRIEVED AT THE OTHER END AS IT THE PIPELINE LENGTH IS COMPLETED .
