| 摘 要： | 灌排系统地下化已在各国成为发展趋势,但单管单用的灌溉或排水系统投资大、成本高,制约了地下灌排系统广泛应用。本试验提出埋设一根地下透水管,使其既起到渗灌作用,也可排地下水,即“一管两用”。本试验从土壤水分运动规律研究了“一管两用”可行性,实验表明“一管”可以达到渗灌与地下排水目的。

| Abstract: | To set up the underground irrigation and drainage system becomes a developing tendency for the countries of the whole world. By using the pipe only for irrigation or drainage will cause greater investment and higher cost which will restrict the popularization of underground irrigation and drainage system. This study suggests to set up one permeable pipe under the ground for both works of irrigation and drainage. That is why authors call such pipe the "bi-utilization pipe" . From the experiments of the soil water movement pattern that shows the "bi-utilization pipe" is able to be used for both irrigation and drainage under the ground. |
