Scope

This Standard specifies minimum requirements for the materials and manufacture of buried corrugated metal structures formed by bolting together plates with sinusoidal profile.
Sinusoidal profiles covered include the following:
(a) B68 (pitch 68 mm) manufactured with either lapped joints or flanged joints.
(b) B152 (pitch 152 mm) lapped joints only.
(c) B200 (pitch 200 mm) lapped joints only.
(d) B230 (pitch 229 mm) lapped joints only.
(e) B381 (pitch 381 mm) lapped joints only.
The structure shapes are as follows (see Figure 1.1):
(i) Pipe.
(ii) Pipe-arch or underpass.
(iii) Horseshoe arch or elliptical arch.
(iv) Arch (one, two or three radius).
(v) Vertical ellipse.
(vi) Horizontal ellipse.
(vii) Metal box.
These structures are intended for use in stormwater drainage and as access tunnels to support roadway and railway and other loadings.
Bolted plate structures are constructed of corrugated section shapes buried in an embankment or in a trench, with correct installation in a soil envelope being essential to the performance of the structure.
This Standard does not consider the additional design requirements for internally pressurized applications.

Guidelines on requirements that may need to be specified at the time of calling for tenders or quotations, and information to be supplied by the manufacturer, are detailed in Appendix A.
Information on means of demonstrating compliance with this Standard is given in Appendix B.
When intended for use in internally pressurized applications, specialist advice should be obtained.
