Product Application
1、 Water conservancy engineering field
In hydraulic engineering, geomembrane is an important anti-seepage material. During the construction of reservoirs and dams, laying geomembranes can effectively prevent water seepage from the reservoir or dam body, ensuring the water storage capacity and structural safety of water conservancy facilities; The use of geomembranes in channels and irrigation systems can reduce leakage losses of water resources during transportation, improve irrigation efficiency, and is particularly suitable for agricultural irrigation projects in arid and water scarce areas.
2、 Environmental engineering field
Environmental engineering has extremely high requirements for anti-seepage, and geomembranes play a crucial role in this regard. In landfills, geomembranes serve as the core anti-seepage layer, which can tightly block the leachate from garbage and prevent it from penetrating into the soil and groundwater, thus avoiding environmental pollution; The sedimentation tank, reaction tank and other facilities of the sewage treatment plant are equipped with geomembranes to prevent leakage, ensuring the orderly progress of the sewage treatment process and preventing sewage leakage from polluting the surrounding environment.
3、 Municipal engineering field
In municipal engineering, the application scenarios of geomembranes are diverse. When constructing landscape water bodies such as artificial lakes and landscape pools, using geomembranes for anti-seepage treatment can ensure stable water volume and maintain the landscape effect; Laying geomembrane on the roof of an underground garage can effectively prevent rainwater or groundwater from seeping into the garage; During the construction of subway tunnels, geomembranes are used for anti-seepage and moisture-proof purposes, ensuring the dryness of the tunnel interior and providing environmental support for the safe operation of the subway.
4、 Transportation engineering field
In transportation engineering, geomembranes are mainly used for foundation treatment and anti-seepage. When treating soft soil foundations of highways and railways, geomembranes can play a role in isolation, separating soft soil from other fillers. At the same time, composite geomembranes can enhance the bearing capacity of the foundation and reduce roadbed settlement; Laying geomembrane as an anti-seepage layer on the roadbed can prevent rainwater from infiltrating into the foundation, avoid the strength of the foundation from decreasing after being soaked in water, and thus ensure the structural stability of roads and railways.
5、 Mining engineering field
In mining engineering, geomembranes are mainly used in tailings ponds. Tailings pond is a place for storing waste such as slag. Laying geomembrane can form an anti-seepage barrier to prevent harmful substances in slag from infiltrating into the surrounding soil and groundwater with rainwater, protecting the ecological environment of the mining area and surrounding areas, and reducing environmental pollution risks.
In summary, geomembranes have irreplaceable applications in many engineering fields such as water conservancy, environmental protection, municipal engineering, transportation, and mining due to their excellent anti-seepage, isolation, and reinforcement properties. It not only ensures the structural safety and stable operation of various projects, but also plays an important role in water resource protection, ecological environment maintenance, and other aspects. It is an indispensable key material in modern engineering construction.
