结合2011西安世园会锦绣湖防渗施工,介绍了施工具体环节如测量放线,膜下土方开挖、平整,复合土工膜铺设、焊接和焊缝检测,膜上土方回填、碾压等应注意的事项,材料选用、施工步骤及采取的技术方法等。结果表明,施工技术满足工程设计要求,解决了湖区防渗问题,效果显著。 Combined with the 2011 Xi’an World Park Fairview Lake anti-seepage construction, introduced the construction of specific links such as measuring the line, earthwork under the film excavation, formation, composite geomembrane laying, welding and weld inspection, membrane earthwork backfill, rolling, etc. should Matters needing attention, materials selection, construction steps and technical methods adopted. The results show that the construction technology meets the engineering design requirements and solves the problem of seepage prevention in the lake area with obvious effects.
