1、Designation: C1479 10Standard Practice forInstallation of Precast Concrete Sewer, Storm Drain, andCulvert Pipe Using Standard Installations1This standard is issued under the fixed designation C1479; the number immediately following the designation indicates the year oforiginal adoption or, in the ca
2、se 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 the installation of precast concretepipe intended to be used for the
3、conveyance of sewage,industrial wastes, and storm water and for the construction ofculverts.1.2 This practice is the inch-pound companion to PracticeC1479M; therefore, no SI equivalents are presented in thispractice.1.3 This standard does not purport to address all of thesafety concerns, if any, ass
4、ociated 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.

Standard Installations6.1 The precast concrete pipe/soil system shall be con-structed to conform to the requirements of Figs. 2 a
16、nd 3 andTables 1 and 2 as designated on the plans.7. Excavation7.1 When rock or other unyielding foundation material isencountered, it shall be removed at least to the requirementsshown in Figs. 2 and 3 and Tables 1 and 2. Overexcavatedareas shall be backfilled with approved materials and com-pacted
17、 to at least the standard proctor density specified for thebedding.7.2 Where surface water or groundwater conditions exist,the site and trench shall be dewatered.8. Foundation8.1 The foundation shall be moderately firm to hard in situsoil, stabilized soil, or compacted fill material.8.2 When unsuita
18、ble or unstable material is encountered,the foundation shall be stabilized.8.3 Methods to prevent migration of soil fines shall beprovided when groundwater or existing soil conditions areconducive to particle migration. Gravelly soils, with little or nofines, could migrate under certain conditions,
19、causing lack ofsupport.8.4 Pipe installed over an unyielding foundation shall becushioned so as to prevent blasting shock when future blastingis anticipated in the area.9. Bedding9.1 The bedding shall be constructed uniformly over the fulllength of the pipe barrel, as required for the designatedstan
20、dard installation, to distribute the loadbearing reactionuniformly on the pipe barrel over its full length, and tomaintain the required pipe grade. See Fig. 4. If placed in layers,FIG. 1 Pipe/Installation TerminologyC1479 102the thickness of the layers shall be as required to achieve thespecified co
21、mpaction and as required by the project specifica-tions.9.2 The bedding layers for standard installation Types 1, 2,and 3 shall be placed to be as uniform as possible, but shall beloosely placed uncompacted material under the middle third ofthe pipe prior to placement of the pipe.9.3 The maximum agg
22、regate size shall be 1 in. when thebedding thickness is less than 6 in. and 112-in. when thebedding thickness is 6 in. or greater, except as noted in 9.4.9.4 When in situ soils conforming to project specificationsare used in constructing the bedding for Type 3 and 4installations, the maximum aggrega
23、te size shall not be greaterthan 3 in., or half the bedding thickness, whichever is less.9.5 The use of aggregate sizes larger than 1 in. shall belimited to 20 % of the bedding material by weight.9.6 Bell holes shall be excavated in the bedding or founda-tion, or both, when installing pipe with expa
24、nded bells so thatthe pipe is supported by the barrel and not by the bells. See Fig.4.9.7 Any outer bedding under the lower side areas shall becompacted to at least the same requirements as for the lowerside areas.10. Pipe Placement and Joining10.1 Pipe shall be installed to the line and grade shown
