집·배수용 투수성 폴리머 콘크리트 관의 농업 수리시설물의 현장적용

Abstract

This study is performed to evaluate performance of the developed pipe when using for underground drainage in farm land, the efficiency of the pipe is examined such as quantity of drainage, water temperature and other field performance in all weather condition.Results of this study, the higher permeability through wall of the pipe is achieved by making various size pores using open-graded aggregate. And in all weather conditions, permeable polymer concrete pipe perform much better than conventional perforated pipes. During rice farming period, quantity of drainage the permeable polymer concrete pipe is 1.28 time greater than conventional perforated pipes.Therefore, use of the permeable polymer concrete pipe is greater advantages when considering collecting and draining capacity compared with conventional perforated pipes.
