How to lay waterproof effect on anti-seepage membrane of fish pond
The fish pond anti-seepage geomembrane is called anti-seepage membrane, and many farmers and fishermen friends are accustomed to call it waterproof membrane. Generally, fish ponds use three specifications of 0.4 mm thick, 0.5 mm thick, and 0.6 mm thick impermeable HDPE geocell manufacturers. Friends in the South refer to the thickness of the membrane as 40 filaments, 50 filaments, and 60 filaments.
So how to lay the construction? After cleaning and leveling the foundation surface of the fish pond, then lay the anti-seepage membrane. When the temperature is high, the membrane relaxes, and when the temperature is low, the plastic geocells manufacturers should be tight. After laying, we have to consider two ideas:
First, from the cost point of view, after laying the film, it is generally the lowest cost way to cover the soil layer with a thickness of at least 30 cm on site, but there are cases of pouring concrete or covering steel plates, of course this cost is higher;
Second, after laying the membrane in the fish pond, you can directly irrigate the water without backfilling the cover soil. Due to the isolation performance of the impermeable membrane, the feces of the fish are retained on the geomembrane, which is convenient for frequent pooling and cleaning in the future. Artificially, it can maintain good water quality for a long time and promote the growth and reproduction of fish, which can increase the yield by 2 to 3 times and improve the economic benefit.
The anti-seepage high quality plastic geocells of the fish pond has a good waterproof effect: after fishing in winter, it is reasonable to plan, first drain the pool water, dig out the debris, and after drying for 1 to 20 days in the winter, spread a layer evenly on the bottom of the pool and the slope 15-20 cm thick clay, then mechanically crushed or rammed. Then lay a layer of 0.5 mm thick impermeable membrane as the impermeable protective layer, accurately measure the relevant dimensions according to the shape of the fish pond, and then cut and splice the impermeable membrane according to the actual situation, the joint between the membrane and the membrane The connection width is usually not less than 15 cm. After laying the fish pond impermeable plastic geocells for sale, you should try to reduce walking and moving things on the membrane surface. Anything that can damage the impervious membrane should not be placed on the membrane or Carry it on the membrane to avoid accidental damage to the membrane. Finally, spread some grass seeds on the slope protection and implement turf slope protection to prevent rain wash.
