(Practice)Standard Practice for Installing Factory-Made Corrugated Aluminum Culverts and Storm Sewer Pipe
Standard Practice for Installing Factory-Made Corrugated Aluminum Culverts and Storm Sewer Pipe
SIGNIFICANCE AND USE
Corrugated aluminum pipe functions structurally as a flexible ring which is supported by and interacts with the compacted surrounding soil. The soil constructed around the pipe is thus an integral part of the structural system. It is therefore important to ensure that the soil structure or backfill is made up of acceptable material and is 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 Method D 698 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 they must be established in the specifications for each project.
SCOPE
1.1 This practice describes procedures, soils, and soil placement for the proper installation of corrugated aluminum culverts and storm sewers in either trench or projection installations. A typical trench installation is shown in , and a typical embankment (projection) installation is shown in . 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 B 790/B 790M.
1.2 This practice is applicable to either inch-pound units as B 788 or to SI units as B 788M. Inch-pound units are not necessary equivalent to SI units. SI units are shown in the text in brackets, and they are the applicable values for metric installation.
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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 bedding, n—the earth or other material on which a
pipe is supported.
3.1.2 haunch, n—the portion of the pipe cross section
between the maximum horizontal dimension and the top of the
bedding.
3.1.3 invert, n—the lowest point on the pipe cross section;
also, the bottom portion of a pipe.
3.1.4 pipe, n—a conduit having full circular shape; also, in
a general context, all structure shapes covered by this practice.
3.1.5 pipe–arch, n—a pipe with an approximate semicircu-
lar crown, small-radius corners, and large-radius invert.
