Sewage pipelines are one of important infra-structures. The main reasons of sewage pipeline failure are improper backfill materials and compaction controls in field. Especially, it is very difficult to compact the lower part of circle pipelines. In order to overcome these problems, the prefabricated light-weight plastic foundation was developed. Couple of load-displacement tests were carried out to get the characteristic of failure.
In this study, the fabricated lightweight plastic foundation using recycled plastic of sewage pipeline was made and PE triple flexible pipe was used to evaluate the fundamental characteristics of foundation for sewage pipeline. Two type of plastic foundation for diameter 300mm pipe with 100% new plastic, and 50% of new and recycled plastic, and three type of plastic foundation for diameter 250mm pipe with 100% new plastic, and 70% of new and recycled plastic, and 100% of recycled plastic were adopted. The basic properties of each plastic materials were evaluated, such as density, elastic modulus, unconfined compressive strength, and bending stress. The allowable load at 5% of pipe deformation was 1.49 ton for 100% new plastics foundation, and 1.35 ton for 50% of new and recycled plastic foundation for diameter 300mm pipe, and 1.09 ton for 100% new plastics foundation, and 1.10 ton for 70% of new and recycled plastic foundation, and 1.20 ton for 100% recycled plastic foundation for diameter 250mm pipe. The use of fabricated lightweight foundation show 90 to 100% of higher load support than without foundation. From the limited laboratory loading tests, the use of prefabricated light-weight plastic foundation is an alternative to solve the difficulty of backfill materials and compaction control.
