Standard Guide for Construction Procedures for Buried Plastic Pipe
SIGNIFICANCE AND USE
This guide may be used as a reference of acceptable open-cut construction practices for the proper installation of buried fiberglass and thermoplastic pipe. This guide may be used as follows:
4.1.1 Installation contractors have an awareness of the level of workmanship required and use this information for bidding purposes and during construction.
4.1.2 Construction inspectors have a reference of acceptable installation practices.
4.1.3 Specification writers may use this guide as a reference in contract documents.
4.1.4 Designers may review this information during planning and design for factors to consider in the preparation of plans and specifications.
4.1.5 The owner of the pipeline may use this guide as a reference for restoration of proper pipe support and embedment when original construction is disturbed due to repairs, modifications, or construction of adjacent or crossing pipelines or cables.
This guide should not be used to replace project specification requirements, manufacturer’recommendations, plumbing codes, building codes, or ASTM installation standards, but may be used to supplement that information.
SCOPE
1.1 This guide describes installation techniques and considerations for open-cut construction of buried pipe. Although this guide was developed for plastic pipe, the concepts of providing the appropriate soil support, care in handling, correct joining techniques, proper soil compaction methods, and prevention of installation damage may apply to any pipe.
1.1.1 Plastic pipe refers to thermoplastic and fiberglass pipe.
1.1.2 Thermoplastic pipe refers to pipe fabricated from polyvinyl chloride (PVC), polyethylene (PE), acrylonitrile-butadiene styrene (ABS), polybutylene (PB), or polypropylene (PP). A list of ASTM specifications for these products is given in .
1.1.3 Fiberglass pipe refers to a glass-fiber-reinforced thermosetting-resin pipe. A list of ASTM specifications for these products is given in . Note 1 cannot be considered inclusive because there may be unlisted, recently adopted ASTM specifications for new products that may be installed using this guide.Note 2
Only a few of the ASTM specifications listed in include the associated fittings. While this guide applies to the installation of pipe, couplings, and fittings, no attempt was made to list all the possible fitting specifications that may be used in conjunction with the pipe specifications. Consult each specification or manufacturer for appropriate fitting standards.
1.1.4For simplification, the term pipe will be used in this document to mean pipe sections, fittings, and couplings.
1.2 This guide contains general construction information applicable for plastic pipe and supplements the installation standards for the various types of pipe as described in Practices D 2321, D 2774, D 3839, F 690, F 1176, and Guide F 645.
1.3 Flexible pipe, such as thermoplastic and fiberglass, are typically designed to rely on the stiffness of the soil surrounding the pipe for support. The contract documents should describe the requirements of an appropriate soil support system. The construction practices described in this guide can be instrumental in attaining the required soil stiffness.
1.3.1 A discussion of the interaction between a buried pipe and the surrounding soil and the importance of attaining proper soil support is in .
1.3.2 Following these guidelines will be helpful in preventing local deformations in the pipe.
1.4 This guide does not cover underwater installation, pipe that needs to be supported on piling, perforated pipe used for drainage, or gas pipelines.
1.5 Pipelines through areas described as "expansive soils," "collapsing soils," landfills or water-logged land (such as swamps) should be constructed using site-specific installation procedures and are not discussed in this guide.
1.6 This guide is not intended to cover all situations. Specific pipe characteristics, fluid transpo...
