在重粘土中埋设水平暗管排水,过滤材料常常采用的是各种级配的砂砾料,从而增加了暗排工程的费用。为了降低暗排工程费用,必须继续寻求新的过滤材料。 从1983年开始,乌克兰科学院水力学研究所就开展了利用发电站炉渣废料作为暗管排水滤料试验研究工作。 Buried in the heavy clay buried in the level of aqueduct, filter materials are often used in various grading gravel, thereby increasing the cost of the project. In order to reduce the cost of hidden row project, we must continue to seek new filter materials. Since 1983, the Institute of Hydraulics of the Ukrainian Academy of Sciences has carried out experimental research on the use of power station slag as a drainage filter for underground pipes.
