n the process of construction of chemical plants, environmental protection measures should be taken, especially the underground anti-seepage treatment. Usually includes the base surface preparation, geomembrane selection, laying, welding, testing and other links.
First of all, the foundation ground is thoroughly leveled and cleaned to ensure that no sharp objects or uneven bumps may damage the geomembrane
Secondly, high-quality geomembranes with appropriate specifications are selected according to engineering needs and accurately measured to reduce waste
Then the geomembrane is successively expanded and fixed on the base layer, and the special welding equipment is used for tight bonding to form a seamless impermeable layer
Finally, its integrity is tested by vacuum test, electric spark test and other methods.
In the entire construction process, in addition to doing the above several links, it is also necessary to pay attention to the maintenance of geomembrane in the later stage.
