Ways to Avoid Aging of Geomembrane
Many engineering construction personnel are concerned about how to avoid aging of geomembrane. Generally speaking, high-quality geomembrane can not only resist various messy stresses, but also can be used for a long time. On the one hand, it is because the anti-aging agent is added to the raw materials of the geomembrane. If there is no anti-aging agent, methods should be adopted to cover the soil layer to avoid aging of the lower anchorage of composite geomembrane.
The inherent characteristics of polymer materials in geomembrane as a means of anti-seepage engineering cannot be completely eliminated, but useful methods can be adopted to extend its service life. The messy terrain is a relatively common construction condition of civil engineering and water conservancy projects, which will also seriously affect the service life of the project. Extend the service life of civil engineering, shorten the construction period and reduce the cost of the project.
After laying the composite geomembrane produced by environmental geomembrane manufacturers, the movement of the composite geomembrane should be minimized to avoid accidental damage to the membrane. There are three connection methods for impermeable membranes, namely bonding welding and vulcanization. Check all seams to avoid seam leakage. The junction of the composite geomembrane and the surrounding chasm can be connected to the anchor groove and the bank slope at the root of the plant during working hours.
If the foundation is a shallow gravel-soaked layer, the gravel should be excavated until the bedrock is injected into the concrete roots and the geomembrane will be fixed in the concrete. Anchoring slots and densely filling backfill.
Generally speaking, the geomembrane is a composite geomembrane that can be used for anti-seepage and flat cushion area and laying a thick transition layer with a thickness of about 30 cm and a particle size of 20 mm. The membrane also needs to be placed on the filter layer when laying, so as to effectively prevent the aging of the suggestions on selecting geomembrane materials.
