1.1本规程涵盖在沟槽或路堤装置中正确安装波纹铝结构板涵洞和下水道的程序、土壤和土壤铺设。典型沟槽安装如所示，典型路堤（投影）安装如所示。本文所述的结构板结构是指工厂制造的板状结构，并在现场用螺栓固定在一起，以提供所需的形状、尺寸和结构长度。本规程适用于按照规程B 790/B 790M设计的结构。 1.2以英寸-磅单位或国际单位制表示的数值应单独视为标准值。在文本中，国际单位显示在括号中。每个系统中规定的值不是精确的等价物； 因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 波纹铝结构板管道在结构上起着柔性环的作用，由压实的周围土壤支撑并与之相互作用。因此，结构周围的土壤是结构系统的组成部分。因此，确保土壤结构由可接受的材料和良好的- 构建。使用试验方法D 1556现场验证土壤结构的可接受性 ，D 2167 ，D 2922 ，或D 2937 ，并将结果与试验方法D 698或D 1557进行比较 根据每个项目的规范，是安装可接受结构的最可靠基础。本规程未规定所需的密度和测量方法，但必须在每个项目的规范中确定。

1.1 This practice covers procedures, soils, and soil placement for the proper installation of corrugated aluminum structural plate culverts and sewers in either trench or embankment installations. A typical trench installation is shown in, and a typical embankment (projection) installation is shown in. Structural plate structures as described herein are those structures factory fabricated in plate form and bolted together on site to provide the required shape, size, and length of structure. This practice applies to structures designed in accordance with Practice B 790/B 790M. 1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 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. ====== Significance And Use ====== Corrugated aluminum structural plate pipe functions structurally as a flexible ring that is supported by and interacts with the compacted surrounding soil. The soil placed around the structure is thus an integral part of the structural system. It is therefore important to ensure that the soil structure is made up of the acceptable material and well-constructed. Field verification of soil structure acceptability using Test Methods D 1556 , D 2167 , D 2922 , or D 2937 , as applicable, and comparing the results with Test Methods D 698 or D 1557 , in accordance with the specifications for each project, is the most reliable basis for installation of an acceptable structure. The required density and method of measurement are not specified by this practice but must be established in the specifications for each project.
