土工膜在废物堆中主要用于底部、边坡的衬砌系统,以及回填物、废物堆等的封闭盖。它还有一个特殊用途,可作为垂直防渗墙的附加隔墙,从而形成一个组合的垂直封闭系统,大大减少污染物质的迁移。设置两个平行的隔板,并用横向隔墙将它分成若干空间,可证明该系统是非常有效的,这样的空格型防渗墙系统可提供一个细致的渗漏监测,并且在污染物向外扩散前便于修理。这种安全性高的处理设施比寿命有限的标准设备更得到公众的认可。
Geomembranes are mainly used in the waste piles for the bottom, the lining of slopes, and the closure caps for backfills, waste piles and the like. It also has a special purpose to serve as an additional barrier to vertical cutoff walls to create a combined vertical closure system that greatly reduces the migration of pollutants. Setting up two parallel partitions and dividing them into a number of compartments with transversal partitions proves to be very effective, such a blanket impermeable wall system provides a detailed leak monitoring and, at the outwards of the contaminants Difficult to repair before diffusion. This safer handling facility is gaining public acceptance than standard equipment with limited life.
