搞要低密度聚乙烯土工膜是一种薄型、连续、柔软的防渗材料，具有质轻、伸长率大、防渗性能好、适应性强、施工简便、造价低廉等特点。水关河水库由于土坝建在强透水地基上，使水库渗漏严重，最多时日渗漏量达5840m3。经过一个冬季后，经常造成干库，致使春灌无水，严重影响厂当地的农业生产。水关河水库经土工膜防渗处理后，渗漏量由原来的69L／s减少到1L／s。 To engage in low-density polyethylene geomembrane is a thin, continuous, soft impermeable material, with light weight, high elongation, impermeability, adaptability, easy construction, low cost and so on. Shui Guanhe Reservoir As the earth dam built on a strong pervious foundation, so that serious leakage of reservoirs, up to a maximum of 5840m3 per day leakage. After a winter, often resulting in dry storage, resulting in spring irrigation water, seriously affecting the local agricultural production plant. Shui Guanhe reservoir after geomembrane anti-seepage treatment, the leakage from the original 69L / s reduced to 1L / s.
