The construction process for tailings landfill anti-seepage is as follows: construction preparation on-site treatment → laying → welding → fixing → protective measures.

Preparation before laying:

1. Before laying the geomembrane, it should be ensured that the laying surface meets the design requirements and quality and safety requirements;

2. The materials and quality of geomembranes and welding rods should comply with the design requirements and relevant standards;

3. Personnel unrelated to laying are not allowed to enter the construction site;

4. All personnel entering the geomembrane construction site must wear entry and exit permits, wear shoes that do not damage the geomembrane, and no one is allowed to smoke upon entering the site;

5. On geotechnical materials, all tools must be handled with care and must not be thrown or placed again. It is strictly prohibited for hot tools to come into contact with the geotechnical membrane;

6. After the construction of geomembrane is completed, attention must be paid to the protection of finished products;

7. During the loading, unloading, and handling of materials, any equipment that may cause mechanical damage to the materials shall not be used. Pulling, lifting, or rolling up is not allowed, and uncontrolled unfolding methods are not allowed. Handle with care.
