Geomembrane application case: Reservoir seepage prevention project
Geomembrane application case: Reservoir seepage prevention project
Geomembrane is a kind of civil engineering material widely used in engineering construction, which has the functions of waterproofing, impermeability and isolation. It plays an important role in water conservancy engineering, road foundation engineering, environmental engineering and other fields. Below I will provide you with a detailed geomembrane application case to show its importance and effect in engineering construction.
Project background
A large reservoir is planned to be built in one area for water supply, irrigation and flood control. However, due to the complex geological conditions, there are more permeable prednisone loose soil layers in the foundation soil, there is a serious leakage risk, so it is necessary to carry out reservoir seepage prevention works to ensure the safe operation of the reservoir.
Engineering design
Geological investigation and analysis: Before the project began, detailed geological investigation and analysis were carried out to determine the geological conditions and the distribution of permeable soil layers, which provided an important basis for the subsequent anti-seepage design.
Geomembrane material selection: According to the geological investigation results, the high-quality geomembrane material is selected, which has excellent waterproof and permeability resistance, and is suitable for dealing with the leakage problem of reservoir engineering.
Construction scheme design: The detailed construction scheme is designed, including the specific location, thickness and connection mode of geomembrane laying, to ensure that the geomembrane can completely cover the permeable soil layer and effectively prevent leakage.
Project implementation
Geomembrane laying: On the surface of the reservoir foundation and dam body, the construction personnel shall lay the geomembrane on the permeable soil layer according to the design requirements to ensure complete coverage, and adopt an effective connection method to ensure the continuity and integrity of the geomembrane.
Connection sealing: In the process of geomembrane laying, strict connection sealing measures are taken, including hot melt connection, mechanical connection, etc., to ensure that the connection between the geomembrane and the geomembrane and the structure is firm, without potential water leakage.
Quality inspection: After the geomembrane is laid, strict quality inspection is carried out, including water pressure test, permeability test, etc., to ensure that the waterproof and impermeable performance of the geomembrane meets the design requirements.
Engineering effect
Effective seepage prevention: After the laying and sealing of the geomembrane, the reservoir is observed and tested for a period of time after water filling, and no leakage phenomenon is found, which effectively prevents the water leakage of the permeable soil layer and ensures the safe operation of the reservoir.
Extension of service life: the application of geomembrane effectively extends the service life of the reservoir, reduces the cost of reservoir maintenance and repair, and improves the economic and social benefits of the reservoir.
Environmental protection: The application of geomembrane not only protects the reservoir structure from erosion and leakage, but also reduces the impact of reservoir pollution on the surrounding environment and protects the ecological environment.
Summary
Through the above cases, we can see the important role and effect of geomembrane in reservoir seepage prevention engineering. Its waterproof, seepage proof, isolation and other functions provide a reliable guarantee for the construction of the project, to ensure the safe and stable operation of the project. I hope this detailed case can help you to have a deeper understanding of the application and importance of geomembrane in engineering construction.
