the newly dug fish pond? Generally, there are two ways to waterproof the newly dug fish pond. The simpler way is to use plastic film for waterproofing. When digging a fish pond, cover the bottom and around with one or two layers of plastic film, so that the water will not seep into the soil. But for a long time, there will still be risks. If you want to ensure that there is no water seepage, you can add a layer of concrete from the bottom and around when digging the fish pond, so as to avoid water seepage.
the leakage of fish ponds 1. Deep dredging: For some shallow fish ponds, the cause of leakage is usually the accumulation of too much silt, which leads to the collapse of the pond slope. This situation should be prevented. Every year after fishing, deep dredging is needed to dig away the silt inside. Keep the water depth at about 2 meters.
2. Mud leakage plugging: If the leakage of the fish pond is not very serious, a layer of fine clay can be laid after the pond is cleaned, and then water is injected into it to make the clay evenly distributed with water flow, so that the effect of plugging can be achieved. When clay and water turn into mud and seep into the crevices below, it can also reduce water permeability.
3. Clay bedding: If the fish pond is relatively large, it is necessary to use clay bedding method to solve the problem of water leakage. Firstly, the water in the pool is drained, the sludge and sundries in the pool are dug out, the pool is aired for 15 to 20 days, a layer of clay with the thickness of 15 to 20 centimeters is evenly laid on the bottom and the periphery of the pool, and then the clay is mechanically rolled or tamped.
