between the section 214 and the drill pipes 124 the air flow then exits out the exit aperture 218 fig3 depicts a flowchart of an exemplary method of utilizing the power swivel 120 according to the flowchart subsurface exploration begins in step 302 with operating the direct push equipment in a normal fashion this operation continues until step 304 when a consolidated or cemented layer is encountered at this point direct push operations cannot continue accordingly the pipes that have been attached to the direct push sensors or sampling device are removed in step 306 one by one from the hole in preparation for drilling once the direct push sensors or sampling devices and pipes are removed the power swivel can be attached in step 308 to the mounting plates and hydraulic rams of the direct push platform as the power swivel weighs about 100 lbs it can be maneuvered into place by personnel at the drill site either manually or with mechanical assistance attachment of the power swivel also includes connecting the power swivel and hydraulic motor to a hydraulic source and an air source next in step 310 the drill bit and sufficient piping to reach the bottom of the borehole are coupled together and lowered into the borehole however before this step is started an air nipple and pack off are inserted into the borehole so that the air flow properly exits from the borehole during drilling in step 312 the drill string and the power swivel are connected together so that the drilling operation in step 314 can take place the drilling operation continues until the consolidated.
