摘要
为保证头屯河水库涵洞在施工期干地施工,围堰防渗问题至关重要。结合地形和地质条件、围堰形式、布置条件、施工条件和工程实际情况,综合考虑材料性能、施工工艺特性、应用经验、经济性等因素,采用复合土工膜和黄土组合防渗技术对围堰进行防渗,以解决围堰的基础、坡面、水平、坝肩等防渗问题。实践表明,此技术的运用,减少了渗漏损失和土料弃渣,降低了工程造价,提高了功效,缩短了工期,防渗效果满足工程要求。
In order to construct the culvert of Toutunhe Reservoir under a dry condition, the seepage control of cofferdam is crucial. After considering the topographical and geological conditions, cofferdam type and layout, construction conditions and materials＇ properties, construction technologies, application experiences and economy, the composite geomembrane and loess are used as a combined seepage control technology for seepage prevention of cofferdam＇s foundation, slopes, level and abutments. The construction practice shows that this technology can reduce leakage loss and soil slag, reduce cost, improve efficiency and shorten construction period, and the seepage control effect meets the requirements of engineering.
