Release time:
2023-08-16
Before laying geomembrane, the corresponding qualified acceptance documents of civil engineering should be provided.
1. Before laying geomembrane, the corresponding qualified acceptance documents of civil engineering should be provided.
2. geomembrane cutting before, should be accurate measurement of its relevant size, and then according to the actual cutting, generally should not be cut according to the size of the drawing, should be numbered piece by piece, detailed records in the special form.
3. When laying geomembrane, we should strive to minimize welded seams, and try to save raw materials under the premise of quality assurance. It is also easy to ensure the quality.
4. Membrane and membrane joints between the lap width is generally not less than 10cm, usually so that the weld alignment direction parallel to the maximum slope, i.e., along the direction of the slope. 5.
5. Usually in the corner and deformed lots, should be the seam length as short as possible. In addition to special requirements, in the slope greater than 1:6 slope from the top slope or stress concentration area within 1.5 meters, as far as possible, do not set up welded seams.
6. geomembrane in the laying, should avoid man-made folds, when the temperature is low, should try to pull tight, paving.
7, geomembrane paving is completed, should minimize walking on the membrane surface, moving tools, etc., where the impermeable membrane can cause harm to the object, should not be placed on the membrane or carry walking on the membrane, so as not to cause accidental damage to the membrane.
