1、复合土工膜防渗施工工艺原理及施工工艺流程中英文翻译Compound geomembrane anti-seepage construction process principle and construction process in both Chinese and English translation 1、 复合土工膜施工工艺原理1, composite geomembrane construction technology principle 复合土工膜是一种土工合成材料，具有较好的防渗效果，一方面将复合土工膜铺设在需要进行防渗处理堤段坡面上，利用自身的连接形成一整体坡面防渗体，另一方
2、面使坡面铺设的复合土工膜的下部与坡脚垂直防渗墙进行连接，使复合土工膜与坡脚防渗墙形成一整体，另外，复合土工膜上部与压顶路肩梁相接，使堤基垂直防渗墙，坡面复合土工膜，堤顶压顶砼形成一个整体完全封闭的防渗体系。Composite geomembrane is a kind of geosynthetic materials, good anti-seepage effect, on the one hand, the composite geomembrane laid side slope in some seepage prevention treatment is required to u
3、se their connections to form a whole slope seepage prevention body, on the other hand to make the bottom of the slope surface of composite geomembrane laid connection with slope toe vertical cut-off wall, composite geomembrane and slope foot cut-off wall to form a whole, in addition, composite geome
4、mbrane upside and coping shoulder beam, the vertical cut-off wall in the dam foundation and slope of composite geomembrane, new coping completely closed anti-seepage concrete forming a whole system. 2、复合土工膜施工工艺流程2, composite geomembrane construction process 在复合土工膜铺设前，大堤迎水面土方填筑及坡面修整完毕，坡面平整度、压实度均达到设计要
5、求并经监理工程师验收合格后方可进行复合土工膜的铺设，本工程复合土工膜铺设的工艺流程如下图2：Before composite geomembrane laying, levee meet the earthwork filling and slope surface dressing, slope surface roughness, degree of compaction shall meet the design requirements and the supervision engineer acceptance rear can for composite geomembrane
6、laid, composite geomembrane laid the technological process of this project are as follows in figure 2: 三、复合土工膜施工方法Three, composite geomembrane construction method 1、 施工准备1, the construction preparation 1）复合土工膜材料质量检测 本工程所用复合土工膜为两布一膜针刺复合土工膜，是国家经贸委公布重点土工合成材料生产企业);企业，湖南湘维有限公司生产产品，使用前委托南京水利科学研究院实验中心对产品的各
7、项技术指标进行检测，各项指标均符合标准规定和设计要求。1) composite geomembrane materials quality testing this project used composite geomembrane to two cloth membrane composite geomembrane, is published by the state economic and trade commission key geosynthetic materials production enterprises); enterprise, hunan hunan d co.
8、, LTD production product, entrusted by nanjing before use water conservancy science research institute technical indicators of experimental center of product testing, the indicators are in line with the prescribed standards and design requirements. 2）堤坡的清理、平整场地，清除一切尖角杂物，欠坡回填夯实、富坡削坡挖平后经监理验收合格，为复合土工膜铺
9、设提供工作面。2) clean up of dike slope and flat field, remove all sharp corners, owe rich backfill compaction of the slope, slope cutting slope dig flat after supervision acceptance, for composite geomembrane laying face. 3）土工膜场内拼接 为了施工方便，保证拼接质量，复合土工膜应尽量采用宽幅，减少现场拼接量，施工前应根据复合土工膜幅宽、现场长度需要，在厂内剪裁，并拼接成合符要求尺寸的块
10、体，卷在钢管上，人工搬运到工作面铺设。3) geomembrane field joining together in order to convenient for construction, ensure the quality of stitching, composite geomembrane breadth should be adopted as far as possible, decrease the scene splicing, before construction should according to the requirements of the composit
11、e geomembrane width, length, cut in the factory, and spliced into the required size of the block, to roll on the steel pipe, manual handling to the face. 2、复合土工膜的铺设2, the laying of composite geomembrane 1）复合土工膜的铺设方法1) the composite geomembrane laid method 复合土工膜铺设分齿槽坡脚平台铺设、坡面铺设两个部分，齿槽坡脚平台铺设结构形式见大样图A，
12、该项工程应在堤基垂直防渗墙施工结束，齿槽开挖符合要求，坡脚平台验收合格后进行。铺设方法：沿防渗墙轴线方向水平滚铺。坡面铺设在坡面验收合格后，从堤顶向堤脚沿垂直于堤轴线方向缓慢展铺到坡脚处与坡脚平台铺设丁字形相接。Composite geomembrane laid the cogging, slope, slope toe platform laid laid two parts, tooth trough slope toe platform laying structure see details A, the project should be at the end of the ver
13、tical cut-off wall construction in the dam foundation, the tooth groove excavation conforms to the requirements, after the acceptance of the slope toe platform. Laid method: along the axis direction of horizontal cut-off wall. Upon the acceptance of spread in slope, slope toe from new slowly along t
