10, high density polyethylene impermeable film is suitable for salt industry: salt farm crystallization pool, brine pool tarp, salt film, salt pool plastic mat film

The construction method
Geomembrane in the process of transportation do not drag, hard drag, to avoid sharp objects stabbed.
1, from the bottom to the high extension, do not pull too tight, should leave 1.50% of the margin, in order to prepare for local subsidence stretching. Considering the actual situation of the project, the slope is laid from top to bottom.
2, adjacent two longitudinal joints should not be in a horizontal line, should stagger more than 1m each other;
3. The longitudinal joint should be more than 1.50m away from the dam foot and the bend foot, and should be located on the plane;
4, slope after bottom;
5, slope laying, film direction should be basically parallel to the maximum slope line.
laying
1. Before laying geomembrane, the corresponding acceptance certificate of civil engineering shall be obtained.
2. Before geomemetic cutting, the relevant size should be accurately measured, and then cut according to the actual size, generally not according to the size shown, should be numbered piece by piece, detailed record in special form.

3. The laying of geomembrane should strive for the minimum weld, under the premise of quality assurance, as far as possible to save raw materials. It is also easy to ensure quality.
4. The lap width of the joint between the film and the film is generally not less than 10cm, usually so that the direction of the weld is parallel to the maximum slope, that is, along the slope direction.
5. Usually in corners and deformed sections, the joint length should be as short as possible. Except for special requirements, no weld shall be installed as far as possible on slopes with a slope greater than 1:6 and within 1.5 meters from the top slope or stress concentration area.
6. In the laying of geomembrane, artificial folds should be avoided. When the temperature is low, it should be tightened and paved as far as possible.
7. After the completion of geomembrane laying, walking on the membrane surface and moving tools should be reduced as far as possible. Objects that can cause harm to the impermeable membrane should not be placed on the membrane or carried on the membrane to walk, so as not to cause accidental damage to the membrane
