　　Two; Construction plan;

　　Geotextile serves as a protective layer for the film, preventing damage to the anti-seepage layer. In order to reduce the ultraviolet radiation and increase the anti-aging performance, the embedding method is adopted.

　　During construction, the first step is to use smaller diameter sand or clay to level the base surface, and then lay it. Do not tighten too tightly, the two ends should be buried in the soil in a corrugated shape, and then a layer of about 10cm transition layer should be laid on top with fine sand or clay. Build 20-30cm stone blocks (or precast concrete blocks) as a protective layer against erosion. During construction, efforts should be made to avoid stones directly hitting the composite film, and the construction of the protective layer should be carried out while laying the film. It should be connected to the surrounding structures using expansion bolts and steel plate pressure strips for anchoring, and the connecting parts should be coated with emulsified asphalt (2mm thick) for bonding to prevent leakage at that location.

　　III Construction matters;

　　(1) The use must be embedded: the covering thickness should not be less than 30cm. It is widely used in reservoir anti-seepage engineering

　　(2) The renovation of the anti-seepage system should consist of a cushion layer, anti-seepage layer, transition layer, and protective layer.

　　(3) The soil should be solid to avoid uneven settlement, cracks, and the grass and tree roots within the anti-seepage range should be removed. Lay a protective layer of sand or clay with small particle size on the contact surface with the membrane.

　　(4) Do not pull too tightly when laying. Our company is responsible for construction/welding

　　Warp knitted composite geomembrane (strong film filament)

　　A new type of geosynthetic material made by compounding synthetic fibers (or glass fibers) with composite geomembranes.

　　Knitted composite geomembrane is different from general geomembranes. Its characteristic is that the intersection of longitude and latitude lines is not curved, and each is in a straight state. Using binding wire to firmly tie the two can comprehensively and uniformly synchronize, withstand external forces, distribute stress, and when the applied external force tears the material, the yarn will gather along the initial crack, increasing the tear resistance strength.

　　When knitting composite, the warp binding line is used to repeatedly pass between the warp, weft, and fiber layers of the geomembrane, so that the three are woven into one. Therefore, warp knitted composite geomembranes not only have the characteristics of high tensile strength and low elongation, but also have the waterproof performance of geomembranes. Therefore, warp knitted composite geomembrane is an anti-seepage material that has the functions of reinforcement, isolation, and protection. It is a highly advanced application of geosynthetic composite materials internationally today.

　　Composite geomembrane is a geotextile anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage applications both domestically and internationally mainly include polyvinyl chloride (PVC), polyethylene (PE), and ethylene/vinyl acetate copolymer (EVA). They are a type of polymer chemical flexible material with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.

　　The service life of composite geomembranes is mainly determined by whether the plastic film loses its anti-seepage and water-resistant properties. According to Soviet national standards, polyethylene films with a thickness of 0.2m and stabilizers used in water engineering can work for 40-50 years under clear water conditions and 30-40 years under sewage conditions. Therefore, the service life of composite geomembrane is sufficient to meet the anti-seepage requirements of the dam.

　　scope

　　The Zhoutou Reservoir dam was originally a core wall dam, but due to the collapse of the dam, the upper part of the core wall was disconnected. To solve the problem of upper anti-seepage, an anti-seepage inclined wall was originally added. According to the safety assessment and analysis of the Zhoutou Reservoir dam, in order to solve the weak leakage surface and dam foundation leakage caused by multiple landslides of the dam, vertical anti-seepage measures such as bedrock curtain grouting, contact surface grouting, flushing and grabbing sleeve well backfilling curtain, and high-pressure spray anti-seepage plate wall were adopted. The upper inclined wall is covered with composite geomembrane for anti-seepage, and is connected to the vertical anti-seepage wall at the bottom, reaching an elevation of 358.0m (0.97m above the check flood level). Please refer to the design drawings for the specific location and quantity of work.

　　Bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material. Bentonite waterproof blankets come in specifications of 3.5, 4.0, 4.5, 4.8, 5.0, 5.5, and 6.0 kilograms (can be produced according to customer requirements). It is protected by spraying grout on a graded natural sodium based bentonite waterproof blanket to protect the working surface. Bentonite waterproof blanket is a geosynthetic material specially used for artificial lake water features, landfills, underground parking lots, rooftop gardens, water pools, oil depots, and chemical storage yards to prevent leakage. It is filled with highly expansive sodium based bentonite between specially made composite geotextiles and non-woven fabrics. The bentonite anti-seepage pad made by needle punching method can form many small fiber spaces, and the bentonite particles cannot flow in one direction. When encountering water, a uniform and high-density gel like waterproof layer is formed inside the pad, effectively preventing water leakage

　　One; Principle of Bentonite Composite Waterproof Blanket;

　　The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into two categories based on its chemical composition: sodium based and calcium based. Bentonite has the characteristic of expanding when it comes into contact with water. Generally, when calcium based bentonite expands, its expansion is only about three times its own volume, while sodium based bentonite adsorbs five times its own weight of water when it comes into contact with water, and its volume expands to more than 15-17 times its original volume. Sodium based bentonite is locked in between two layers of geosynthetic materials to protect and reinforce GCL, giving it a certain overall shear strength.
