1.1 本规程涵盖了按照规范生产的波纹钢管和管拱的正确安装程序、土壤和土壤放置 A760/A760M 或 A762/A762M 在沟槽或路堤安装中。本规程还包括波纹钢管的安装，用于不涉及回填或土壤-结构相互作用的替代用途。 1.2 典型沟槽安装和典型路堤（投影）安装如所示 无花果。1和 2. 分别地本规程中描述的管道在工厂制造，并提供给作业，长度通常为10至30 ft[3至9 m]，通常为20 ft[6 m]，用于现场连接。 本规程适用于按照规程设计的结构 A796/A796M . 图1 典型沟槽安装 图2 典型路堤（投影）安装 1.3 单位- 本规程适用于以英寸-磅为单位的设计 A798型 或以国际单位制表示 A798M . 英寸磅单位和国际单位不一定相等。为清楚起见，文本中的括号中显示了国际单位制，但它们是根据本规范进行安装时的适用值 A798M . 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This practice covers procedures, soils, and soil placement for the proper installation of corrugated steel pipe and pipe-arches produced to Specification A760/A760M or A762/A762M , in either trench or embankment installations. This practice also covers installation of corrugated steel pipe for alternative uses that do not involve backfilling or soil-structure interaction. 1.2 A typical trench installation and a typical embankment (projection) installation are shown in Figs. 1 and 2 , respectively. The pipes described in this practice are manufactured in a factory and furnished to the job in lengths ordinarily from 10 to 30 ft [3 to 9 m], with 20 ft [6 m] being common, for field joining. This practice applies to structures designed in accordance with Practice A796/A796M . FIG. 1 Typical Trench Installation FIG. 2 Typical Embankment (Projection) Installation 1.3 Units— This practice is applicable to design in inch-pound units as A798 or in SI units as A798M . Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text for clarity, but they are the applicable values when the installation is to be performed in accordance with A798M . 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
