防渗土工膜在人工湖防渗防水工程中的应用

北京人工湖防渗材料：HDPE土工膜施工方法
HDPE土工膜施工方法：
     HDPE土工膜在运输过程中不要拖拉、硬拽，避免尖锐物刺伤。
     1、应从底部向高位延伸，不要拉得太紧，应留有1.50%的余幅，以备局部下沉拉伸。考虑到本工程的实际情况，边坡采取从上到下的铺设顺序； 
     2、相邻两幅的纵向接头不应在一条水平线上，应相互错开1m以上； 
     3、纵向接头应距离坝脚、弯脚处1.50m以上，应设在平面上； 
     4、先边坡后场底； 
     5、边坡铺设时，展膜方向应基本平行于坡度线。
Beijing artificial lake anti-seepage material: HDPE geotechnical membrane construction method
HDPE geotechnical membrane construction method:
HDPE geotechnical membrane in the process of transportation do not drag, drag, avoid sharp stick injury.
1, from the bottom to the upper extension, do not pull too tightly, there should be 1.50% of the paintings, for the local subsidence stretching. Considering the actual conditions of the project, from top to bottom slope by laying order;
2, two adjacent longitudinal joints shall not in a horizontal line, should be staggered over 1m;
3, longitudinal joints shall be above 1.50M, bending at the distance of the foot, should be located in the plane;
In 4, the first back bottom slope;
5, the slope paving, film spreading direction substantially parallel to the maximum gradient line.
