摘要:
暗管排水治理盐渍化问题是利用江苏省丰富沿海滩涂资源的有效途径,但由于土壤渗透性低、结构较差,暗管存在较大的淤堵风险,亟须筛选适合当地土质的土工布合成外包滤料。研究选取4种土工布外包滤料进行水力渗透试验,分析比较在2种土壤中的透水、反滤与防淤堵性能。结果显示,试验进行至70 d时,8组处理均达到稳定,渗透性能良好,土壤流失量均不超过1 g,淤堵率在6%~20%之间。4种土工布在砂粒含量较高的土壤A中能更快达到稳定,所形成的天然反滤层结构更佳,土工布SF44各性能表现均为更优。研究成果可为江苏省沿海滩涂地区暗管排水土工布外包滤料的选择提供理论支撑和技术参考。
Abstract:
It is an effective way to treat the salinization problem by using the rich coastal mudflat resources in Jiangsu Province. However, due to the low permeability and poor structure of the soil, there is a great risk of silting in the concealed pipe, it is urgent to select the synthetic geotextile filter material suitable for the local soil. In this study, four kinds of geotextile filter materials were selected for hydraulic permeability test, and the performance of water permeability, reverse filtration and anti-silting in two kinds of soil was analyzed and compared. The results showed that after 70 days of experiment, all the 8 groups were stable, the permeability was good, the soil loss was less than 1 gram, and the siltation rate was between 6% and 20%. The four geotextiles can reach stability faster in soil A with higher sand content, and the natural inverted filter structure formed is better, and the performance of geotextile SF44 is better. The research results can provide theoretical support and technical reference for the selection of geotextile filter materials for underground drainage in coastal mudflat areas of Jiangsu Province.
