Abstract:

A new lightweight PVC pipe, consisting of a smooth inner wall and a corrugated outer wall, has been introduced in the U. S. sanitary sewer market in 4 through 10 in. diameters. Field burial tests were conducted to investigate its structural performance. Pipe deflections due to compaction of embedment soil were minor. All responses appear to have stabilized after 1 year with pipe ring deflections less than 3. 5% in all but the uncompacted clay condition. Predicted initial deflections by traditional methods agree fairly well with measurements. Based on 1 year data, long-term deflections are somewhat overestimated by traditional deflection lag concepts. Results show that this pipe installed as described in ASTM D 2321 will exhibit acceptable deflections.
