Abstract

一种复合土工膜堰心围堰，属于水利水电工程技术领域，其特征是：对两个土工膜连接边缘折叠曲压，在折叠曲压的连接处通过木条压紧，在方木条上穿过铁钉固定。有益效果是：操作简单，对操作工人的操作水平不高；缩短工序时间，施工成本低，降低工人的劳动强度，提高领导生产率。

Description

一种复合土工膜堰心围堰
技术领域
本实用新型属于水利水电工程技术领域。特别适用于水电站临时围堰防渗体建造。
背景技术
在目前国内水利工程中围堰建造中，我国目前已修建各类型的水库八万六千余座，以土石坝居多。在这些土石坝工程中普遍采用塑性粘土心墙、斜墙或刚性的混凝土心墙、斜墙为防渗体的传统结构形式的建造方法。这种建造方法存在着诸如工艺复杂、造价高、工期长、占用耕地多且施工受气候因素影响大等一些不足。复合土工膜作为防渗体的围堰结构形式已经很普及，防渗体复合土工膜间的连接为胶接、热熔接或缝接。胶接对环境要求高，而且对胶接处的土工膜进行烘干，胶接的强度不易保证；热熔接改变了土工膜受力结构；缝接针孔过多，影响防渗效果；以上三种方法工艺复杂、工期长。
发明内容
本实用新型的目的是：提供一种复合土工膜堰心围堰，它在围堰建造中，对土工膜间的连接工作过程，安全可靠、防渗效果好、施工简便、缩短工期、不受气候影响并减轻劳动强度
本实用新型的技术方案是：对两个土工膜连接边缘折叠曲压，在折叠曲压的连接处通过木条压紧，在方木条上穿过铁钉固定。
本实用新型的有益效果是：操作简单，对操作工人的操作水平不高；缩短工序时间，施工成本低，降低工人的劳动强度，提高领导生产率。
附图说明
图1是本实用新型侧剖视图。
具体实施方式
下面结合附图对本实用新型做进一步描述：
如图所示，1是上片土工膜，2是下片土工膜，3是方木条，4是铁钉。
因土工膜是软体片状，所以首先将上片土工膜1和下片土工膜2的接缝边缘重叠，然后再把接缝边缘卷曲压紧，在接缝边缘两侧加装方木条3，最后用铁钉4在方木条3穿过固定，使上片土工膜1和下片土工膜2连为一体，其它土建工程不变。
