Tunneling Apparatus Including Vacuum and Method of Use
The present disclosure relates to a tunneling apparatus including a pipe string having a distal end and a proximal end. The pipe string includes a plurality of pipe-sections connected end-to end. The pipe string also includes a cutting head coupled to a distal-most one of the pipe-sections. The pipe...

| description | The present disclosure relates to a tunneling apparatus including a pipe string having a distal end and a proximal end. The pipe string includes a plurality of pipe-sections connected end-to end. The pipe string also includes a cutting head coupled to a distal-most one of the pipe-sections. The pipe string defines a vacuum passage that extends through the pipe string from the proximal end to the distal end of the pipe string. A source of vacuum is in fluid communication with the vacuum passage for drawing cuttings through the vacuum passage. A blockage sensor can be used for sensing whether a precursor blockage condition exists within the vacuum passage. A source of air pressure can be used to force air distally through the pipe string to assist in moving cuttings proximally through the vacuum passage. |
