Sep 13,2017·Horizontal directional drilling (HDD) is becoming widely accepted in the construction industry as a convenient way to get a pipeline drilling job done with minimum disruption to everyday life.It has gained interest mainly due to the fact that HDD projects do not involve digging up entire stretches of roads,though the entry and exit points have to be dug and cordoned off.Horizontal Directional DrillingHorizontal Directional Drilling for Placement of PE Pipe or Conduit Under Obstacles,Including River Crossings, and in the ASCE Manual of Practice 108,Pipeline Design for Installation by Directional Drilling. 421-461dd 421 1/16/09 10:15:03 AMImages of Gs450at L Pipeline Crossing drilling Rig imagesPeople also askHow does a drill rig crossing work?How does a drill rig crossing work?When the bore head and rod emerge on the opposite side of the crossing,a special cutter,called a back reamer,is attached and pulled back through the pilot hole.The reamer bores out the pilot hole so that the pipe can be pulled through.The pipe is usually pulled through from the side of the crossing opposite the drill rig.Horizontal Directional Drilling - Conduit Division
