1、Designation:F298514Standard Practice forInstallation of a PVC Segmental Panel Liner System in Man-Entry Size Sewers and Conduits1This standard is issued under the fixed designation F2985;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revisio
2、n,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 The practice describes the procedures for the rehabili-tation of gravity pipes,culverts,tunnels,and conduits
3、by theinstallation of a field-fabricated PVC liner system.Afterinstallation of the liner system,cementitious grout is pumpedinto the annular space between the liner and the host structure.The rehabilitation of the host structure by this installationpractice results in a rigid composite structure(PVC
4、 liner/grout/existing pipe).This type of rehabilitation process is suitable fora variety of gravity pipe applications such as storm sewers,sanitary sewers,and culverts;and with geometries includingcircular,egg,ovoid,elliptical,arch,and site-specific compositeshapes.1.2 The values stated in inch-poun
5、d units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsi
6、bility 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:2C109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm C
