Abstract

Sewage pipelines are one of important infra-structures. The main reasons of sewage pipelint failure are improper backfill materials and compaction controls in field. Especially, it is very difficult to compact the lower part of circula 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. 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.

하수관거는 중요한 사회간접시설중의 하나이다. 이러한 하수관거의 파손은 주로 하수관거의 시공에 이용되는 뒤채움재의 부적절한 품질관리 및 다짐관리로 인하여 발생한다. 특히, 원형관로의 경우 현장에서 다짐작업이 어려워 다짐기준을 만족시키기 어렵다. 이러한 문제를 해결하기 위하여 본 연구는 플라스틱 현장조립식 경량기초를 개발하였다. 개발된 경량기초의 하중재하시험 및 변형특성을 평가하였다. 제한된 실험결과로부터 현장조립식 플라스틱 경량기초의 사용은 뒤채움재의 다짐관리시 발생하는 어려움을 줄여줄 수 있는 대안으로 사용 가능함을 확인하였다.
