1、Designation: F1962 11An American National StandardStandard Guide forUse of Maxi-Horizontal Directional Drilling for Placement ofPolyethylene Pipe or Conduit Under Obstacles, IncludingRiver Crossings1This standard is issued under the fixed designation F1962; the number immediately following the desig
2、nation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This guide describes the desig
3、n, selection consider-ations, and installation procedures for the placement of poly-ethylene pipe or conduit below ground using maxi-horizontaldirectional drilling equipment. The pipes or conduits may beused for various applications including telecommunications,electric power, natural gas, petroleum
4、, water lines, sewer lines,or other fluid transport.1.2 Horizontal directional drilling is a form of trenchlesstechnology. The equipment and procedures are intended tominimize surface damage, restoration requirements, and dis-ruption of vehicular or maritime traffic with little or nointerruption of
5、other existing lines or services. Mini-horizontaldirectional drilling (min-HDD) is typically used for the rela-tively shorter distances and smaller diameter pipes associatedwith local utility distribution lines. In comparison, maxi-horizontal directional drilling (maxi-HDD) is typically used forlong
6、er distances and larger diameter pipes common in majorriver crossings. Applications that are intermediate to themini-HDD or maxi-HDD categories may utilize appropriate“medi” equipment of intermediate size and capabilities. In suchcases, the design guidelines and installation practices wouldfollow th

8、dered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of the regulatory limitations prior to
9、use. Section 6contains general safety information related to the use ofmaxi-horizontal directional drilling equipment.2.
