Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of HOPE Pipe

摘要

A set of guidelines for the use of mini-horizontal direc-tional drilling (mini-HDD) has recently been developed by the Plastics Pipe Institute. Technical Report TR-46, Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of High Density Polyethylene Pipe, represents a comprehensive set of information supporting the placement of HDPE pipe by mini-HDD equipment.The new document is intended to provide information analogous to that provided in ASTM F 1962, Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossings, but at a level appropriate for the less complex mini-HDD technology and typical project characteristics.
