(Practice)Standard Practice for Installation of a PVC Segmental Panel Liner System in Man-Entry Size Sewers and Conduits
Standard Practice for Installation of a PVC Segmental Panel Liner System in Man-Entry Size Sewers and Conduits
SCOPE
1.1 The practice describes the procedures for the rehabilitation of gravity pipes, culverts, tunnels, and conduits by the installation of a field-fabricated PVC liner system. After installation of the liner system, cementitious grout is pumped into the annular space between the liner and the host structure. The rehabilitation of the host structure by this installation practice results in a rigid composite structure (PVC liner/grout/existing pipe). This type of rehabilitation process is suitable for a variety of gravity pipe applications such as storm sewers, sanitary sewers, and culverts; and with geometries including circular, egg, ovoid, elliptical, arch, and site-specific composite shapes.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
