Different Applications of Geomembrane and Composite Geomembrane in Anti-seepage Engineering of Aquaculture

After winter fishing, rational planning, first drain the pond water, dig out the debris, and dry it for 1 to 20 days in the winter, then evenly lay a layer of 15-20 cm thick clay on the bottom and slope of the pond, and then use machinery Rolled or tamped. Then lay a layer of 0.5 mm thick impervious film as the impervious protective layer, accurately measure the relevant dimensions according to the shape of the fish pond, and then cut and splice the impervious film according to the actual situation. The overlap width of the seam between the film and the film Generally not less than 15 centimeters. After the impermeable membrane is laid, walking on the membrane surface and moving tools should be minimized. Any objects that can cause harm to the impermeable membrane should not be placed on the membrane or carried on the membrane. Walk to avoid accidental damage to the membrane. Finally, some grass seeds were spread on the slope protection, and turf slope protection was implemented to prevent rain erosion.

The anti-seepage of fish ponds is more commonly used as a high quality LDPE geomembrane. It is a single-layer high-density geomembrane. There is no non-woven fabric on both sides. Why use this? Because non-woven fabrics are recycled Made of materials, non-woven fabrics that do not completely volatilize toxic substances will cause serious damage to the school of fish. In addition, the smooth appearance of the geomembrane can effectively prevent fish from escaping during the rainy season, especially like lobster, crab, turtle, loach, yellow croaker Good at running fish.

At present, fish pond farming often encounters conditions such as long-term drought and low rainfall, which causes the groundwater level to drop, and the water permeability of the soil in the fish pond to be large, which will cause fish pond leakage. Now most farmers are laying anti-seepage geomembrane on the bottom of the fish pond. Let’s analyze its necessity. The application of anti-seepage geomembrane for fish pond breeding has well solved the problem of anti-seepage for fish pond breeding. We remind the majority of fish pond breeding professional households that it is necessary to lay out anti-seepage geomembrane for fish pond breeding.

There are two types of anti-seepage membranes for farming: one is a composite geomembrane and the other is a geomembrane. These two kinds of anti-seepage membranes have their own advantages when they are used in the cultivation. Their two main functions are anti-seepage. In terms of leakage, their effects are the same. People often require them to have more functions during use. In addition to the function of anti-seepage, other functions determine their place of use. Let me talk about the lotus pond and What are the differences between the selection of anti-seepage geomembrane for fish ponds? How should the high quality textured geomembrane be used for anti-seepage in fish ponds and anti-seepage for fish ponds?

Muchi anti-seepage film Most people choose to use composite geomembrane. Non-woven fabric on both sides is white geomembrane. Non-woven fabric on both sides effectively protects the middle geomembrane. The key to preventing water leakage in Muchi is the middle. Geomembrane, the cloth on both sides prevents humans and animals from directly destroying the middle membrane and also prevents the lotus root from damaging the membrane during the growth process. That is to say, the composite geomembrane can prevent the lotus root from penetrating and continuing to grow downward. Most infiltration people will choose composite geomembrane.
