고속도로 하부 횡단 배수시설로 사용되는 파형 플래스틱 관의 덮개 요건

초록

This project investigated the use of two types of thermoplastic pipes, High-Density Polyethylene (HDPE) and Poly-vinyl Chloride (PVC), as cross-drains under highways. Pipes ranging from 0.3 m (12 in.) to 1.5 m (60 in.) in diameter were evaluated under deep fills, minimum cover, and construction loads. In addition to a comprehensive literature review, an analytical study into the allowable fill heights for thermoplastic pipes and a field study to observe the installation and performance of the pipe in service conditions were conducted. Based on the study findings, recommendations regarding how and when thermoplastic pipe should be installed are provided.
