智能化毛细渗灌节水技术在京张高铁路堤边坡绿化中的应用

The Application of Intelligent Capillary Irrigation Water Conservation Technology in Jing-Zhang High Speed Railway Subgrade Slope Greening

绿色生态铁路的设计理念对铁路路堤边坡绿化提出了更高的要求,由于铁路路堤边坡呈带状分散分布,对于气候条件恶劣或少雨地区,带来了后期的浇灌养护困难问题。渗灌节水技术可以较好解决交通线路沿线的绿化浇灌问题,但淤堵问题是传统渗灌节水技术推广应用中的一个难题。以京张高铁路堤边坡绿化工程为试验段,提出一套基于毛细透排水带为渗灌材料的智能化毛细渗灌节水技术。试验结果表明,以毛细透排水带作为毛细渗灌材料解决了渗灌淤堵问题,具有很好的节水效应;智能化毛细渗灌节水技术实现了自动监测、自动灌溉及远程智能化管理,解决了铁路边坡绿化浇灌养护问题,效果良好。

The design philosophy of green ecology railway raises higher demands for the greening of subgrade slope.The zonal distribution of railway subgrade slope brings difficulties to irrigation maintenance in areas of harsh weather condition or little rain.The infiltrating irrigation can solve the problem of irrigation along the railway whereas siltation limits its general application.This article adopts a new intelligent capillary irrigation technology based on capillary-fringe belt drain and applies it in the subgrade slope greening project of Jing-Zhang High-Speed Railway.The results show that irrigation using capillary-fringe belt drain can solve the problem of siltation with superior water conservation effect.The intelligent capillary irrigation water conservation technology offers a better solution for subgrade slope greening maintenance by its automatic monitoring,automatic irrigation and remote intelligent management.
