AS/NZS 2041.2:2011 PDF Download

The AS/NZS 2041.2:2011 standard outlines the requirements for the proper installation of corrugated metal structures that are buried underground. These structures are commonly used for stormwater drainage systems and as access tunnels to support roadways, railways, and other types of loadings. It emphasizes the importance of correct installation to ensure optimal performance of the structures.

One key aspect highlighted in the standard is the reliance of the corrugated metal structures on soil-structure interaction. This means that the structures must be properly installed to ensure that they interact effectively with the surrounding soil. In order to meet the design criteria for strength, it is essential to achieve adequate compaction of the fill material specified for backfilling.

The standard also warns about the potential consequences of incorrect backfilling procedures. It states that failure to follow the proper process may lead to the collapse of the culvert, which can cause significant damage or disruption. Therefore, the standard serves as a guide to ensure that correct installation practices are followed, reducing the risk of structural failure and ensuring the longevity of the buried corrugated metal structures.
