Drainage Property of the Perforated Clay Pipe

Abstract

Under soil conditions of water left over in the field from rainfall and underground springs, drains are needed to quickly get rid of excessive water. A drainage system using drain pipes is an effective technical method in this case. A new clay pipe with many holes. 5mm in diameter at the cylinder wall, was developed for this study. In repeated experiments, the drainage function of the new clay pipe is compared with a clay pipe of the same material but with no holes. As a result of effective drainage by the arch structure that is formed around the holes, soil is prevented from inflowing to the pipes and promotes high drainage. Thus, this new clay pipe can be used as a pipe drain at medium depth in farmland and has proved to be a promising drain material.
