1、Designation: A 807/A 807M 02 (Reapproved 2008)Standard Practice forInstalling Corrugated Steel Structural Plate Pipe for Sewersand Other Applications1This standard is issued under the fixed designation A 807/A 807M; the number immediately following the designation indicates the yearof original adopt
2、ion or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers procedures, soils, and soil place-ment for the prope
3、r installation of corrugated steel structuralplate pipe, pipe-arches, arches, and underpasses produced toSpecification A 761/A 761M, in either trench or embankmentinstallations. A typical trench installation and a typical em-bankment (projection) installation are shown in Figs. 1 and 2,respectively.
4、 Structural plate structures as described herein arethose structures factory fabricated in plate form and boltedtogether on site to provide the required shape, size, and lengthof structure. This practice applies to structures designed inaccordance with Practice A 796/A 796M.1.2 This standard does no
5、t purport to address all of thesafety concerns, if any, associated 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.1.3 The values stated in either inch-pou
6、nd units or SI unitsshall be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem must be used independently of the other, withoutcombining values in any way. SI units are shown in brackets inthe text for clarity, but they are the appli
7、cable values when theinstallation is to be performed using SI units.2.

Significance and Use4.1 Structural plate structures function structurally as aflexible ring that is supported b
17、y and interacts with thecompacted surrounding soil. The soil placed around the struc-ture is thus an integral part of the structural system. It istherefore important to ensure that the soil structure is made upof acceptable material and is well constructed. Field verifica-tion of soil structure acce
18、ptability using Test Methods D 1556,D 2167, D 2922,orD 2937, as applicable, and comparing theresults with either Test Methods D 698 or D 1557, in accor-dance with the specifications for each project, is the mostreliable basis for installation of an acceptable structure. Therequired density and metho
19、d of measurement are not specifiedby this practice, but must be established in the specificationsfor each project.5. Trench Excavation5.1 To obtain the anticipated structural performance ofstructural plate structures, it is not necessary to control trenchwidth beyond the minimum necessary for proper
20、 assembly ofthe structure and placement of the structural backfill. However,the soil on each side beyond the excavated trench must be ableto support anticipated loads. Any sloughed material shall beremoved from the trench or compacted to provide the neces-sary support. When a construction situation
21、calls for a rela-tively wide trench, it may be made as wide as required, for itsFIG. 1 Typical Trench InstallationFIG. 2 Typical Embankment (Projection) InstallationA 807/A 807M 02 (2008)2full depth if so desired. However, trench excavation must be incompliance with any local, state, and federal cod
22、es and safetyregulations.6. Foundation6.1 The supporting soil beneath the structure must provide areasonably uniform resistance to the imposed load, bothlongitudinally and laterally. Sharp variations in the foundationmust be avoided. When rock is encountered, it must beexcavated and replaced with so
23、il. If the structure is to be placedon a continuous rock foundation, it will be necessary to providea bedding of soil between rock and structure. See Fig. 3.6.2 Lateral changes in foundation should never be such thatthe structure is firmly supported while the backfill on eitherside is not. When soft
24、 material is encountered in the structureexcavation and must be removed to maintain the grade (limitsettlement) of the structure, then it must be removed, usuallyfor a minimum of three structure widths (see Fig. 4). A smallerwidth of removal can sometimes be used if established by theengineer.6.3 Pe
