摘要

摘要: 排水管井作为一种渗流控制措施,在水利工程中应用广泛。但管井容易发生淤堵,为延长其使用寿命,根据已有淤堵机理研究成果,提出一种新型可拆换过滤器应用于排水管井。其工作原理是通过在传统排水管井壁内设置一个可拆换的多孔泡沫塑料过滤器,使部分物理淤堵物和大多数化学及生物淤堵物沉积于多孔泡沫塑料过滤器内。当过滤器在受到淤堵后通过对其进行更换或清洗,可恢复管井的排水能力。在水利工程坝基排水孔、堤防工程减压井以及航道岸坡水平排水孔等方面的应用成果表明可拆换式过滤器可以大幅延缓排水管井的使用寿命,改善其排水效果,使用前景十分广阔。

Abstract: Drainage well is a widespread application of seepage control in water conservancy projects. However, the well is prone to clogging. To extend its life, a removable filter is applied to the drainage well according to the research findings of clogging. The working principle is to make part of physical clogging or most of chemical and biological clogging occur in the removable porous foamed plastic filter which is placed in the drainage well. The filter can be taken out to clean or alternate to regain its drainage ability. The applications in dam foundation drainage holes, relief wells of dikes and horizontal drainage holes of channel banks show that the removable filters can extend the life of drainage wells significantly and their future is prosperous.
