Designation:F175997(Reapproved 2010)Standard Practice forDesign of High-Density Polyethylene(HDPE)Manholes forSubsurface Applications1This standard is issued under the fixed designation F1759;the number immediately following the designation 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.Scope1.1 This practice covers general and basic procedures re-lated to the design of manholes and components manufacturedfrom high-density polyethylene(HDPE)for use in subsurfaceapplications and applies to personnel access structures.Thepractice covers the material,the structural design requirementsof the manhole barrel(also called vertical riser or shaft),floor(bottom),and top,and joints between shaft sections.1.2 This practice offers the minimum requirements for theproper design of an HDPE manhole.Due to the variability inmanhole height,diameter,and the soil,each manhole must bedesigned and detailed individually.When properly used andimplemented,this practice can help ensure a safe and reliablestructure for the industry.1.3 DisclaimerThe reader is cautioned that independentprofessional judgment must be exercised when data or recom-mendations set forth in this practice are applied.The publica-tion of the material contained herein is not intended as arepresentation or warranty on the part of ASTM that thisinformation is suitable for general or particular use,or freedomfrom infringement of any patent or patents.Anyone making useof this information assumes all liability arising from such use.The design of structures is within the scope of expertise of alicensed architect,structural engineer,or other licensed profes-sional for the application of principles to a particular structure.1.4 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are providedfor information only.1.5 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 regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD2321 Practice for Underground Installation of Thermoplas-tic Pipe for Sewers and Other Gravity-Flow ApplicationsD2657 Practice for Heat Fusion Joining of Polyolefin Pipeand FittingsD2837 Test Method for Obtaining Hydrostatic Design Basisfor Thermoplastic Pipe Materials or Pressure Design Basisfor Thermoplastic Pipe ProductsD3035 Specification for Polyethylene(PE)Plastic Pipe(DR-PR)Based on Controlled Outside DiameterD3212 Specification for Joints for Drain and Sewer PlasticPipes Using Flexible Elastomeric SealsD3350 Specification for Polyethylene Plastics Pipe and Fit-tings MaterialsF412 Terminology Relating to Plastic Piping SystemsF477 Specification for Elastomeric Seals(Gaskets)for Join-ing Plastic PipeF714 Specification for Polyethylene(PE)Plastic Pipe(DR-PR)Based on Outside DiameterF894 Specification for Polyethylene(PE)Large DiameterProfile Wall Sewer and Drain Pipe3.Terminology3.1 Definitions:3.1.1 Definitions used in this practice are in accordance withTerminology F412 and Terminology D1600 unless otherwiseindicated.3.2 Definitions of Terms Specific to This Standard:3.2.1 anchor connection ringan HDPE ring attached tothe manhole riser on which to place an antiflotation device,such as a concrete anchor ring.1This practice is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.26 on OlefinBased Pipe.Current edition approved April 1,2010.Published May 2010.Originallyapproved in 1997.Last previous edition approved in 2004 as F1759-97(2004).DOI:10.1520/F1759-97R10.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.2 archingmobilization of internal shear resistancewithin a soil mass that results in a change in soil pressureacting on an underground structure.3.2.3 benchingthe internal floor of a manhole when it iselevated above the manhole invert,usually provided as a placefor personnel to stand.3.2.4 closed profilea manhole barrel construction thatpresents an essentially smooth internal surface braced withprojections or ribs,which are joined by an essentially smoothouter wall.Solid wall construction is considered a special caseof the closed profile.3.2.5 downdragdownward shear force acting on theshafts external surfac
