AS/NZS 2041:1998 pdf free.Buried corrugated metal structures.
AS/NZS 2041 specifies requirements for materials, manufacture, design methods arid installation of buried corrugated metal pipes, pipearches, arches and special shapes comprising bolted corrugated metal sheets or plates manufactured within the limits given in Table I. I and Section 2. It deals only with those structures in which the sheets or plates have circumferential corrugations running normal to the longitudinal axis of the structures.
The Standard does not cover the design of arch footings, rib stiffening or those structures covered by AS 1731, AS 1762, AS 3703.1 and AS 3703.2.
I Ordering guidelines arc detailed in Appendix A. Information on the means of demonstrating compliance with (his Standard for manufacture of the metal conlponcnts is given in Appendix B. Information on the assessment of durabiLity is given in Appendix C.
2 Buried corrugated metal sructures withstand applied loads hrough the interactive behaviour of the flcxiblc metal ring and the surrounding soil envelope. The stiffness of both of these materials is considered during design.
1.2 NEW MATERIALS AND METHODS This Standard does not preclude the use of corrugated profiles, cross-sections, materials or installation methods other than those speciheci in this Standard, provided that such new corrugated proflics, cross-sections or materials have been proven by appropriate performance testing to be equal to or better than those described herein.
NOTE: Variations In cross—sectional shape, corrugation profile, material or backfill characteristics, including the degree of compaction. may have significant effects on the performance of these structures.
1.4 DEFINITIONS For the purpose of this Standard, the definitions given in AS/NZS 3500.0 and those below apply.
NOTE: Where a definition given conflicts with that given in AS/NZS 3500.0, the definition given below applies.
1.4.1 Administrative definitions Manufacuirer—the person(s) or corporate body responsible for the manufacture of the pipes, pipe-arches, arches or special shapes. Purchaser—the person(s) or corporate body for whom the manufacturer has contracted to manufacture or supply the pipes, pipe-arches, arches or special shapes.
1.4.2 Technical definitions Barrier coating—a coating designed to isolate the substrate from the environment. Bedding— a prepared layer of uncompacted, non-cohesive material placed over the foundation, below the structure invert. Camber—a variation to the bedding grade along the structure invert to compensate for differential settlement. Compaction—the process of soil densification, at a specified moisture content, through the application of load by rolling, tamping, rodding or vibration with mechanical or manual equipment.AS/NZS 2041 pdf download.
