the bottom of the fish pond with cement or with geomembrane 1. The bottom of the fish pond is better with geomembrane. The so-called geomembrane is a kind of polymer flexible material, its proportion is relatively small, and has strong extensibility, but also can adapt to degeneration, not only corrosion resistance and low temperature resistance, but also environmentally friendly. If you use cement, although it can do not seepage, but itself is not breathable, and the fish think of holes can not do, and even affect the survival of some demersal fish. 2. Take grass carp as an example. Grass carp is a kind of food fish. This fish is found in many parts of the country, and it is common to raise it in captivity. However, since water plants cannot be grown in cement ponds, it must be fed with plant bait frequently so that it can grow quickly. Therefore, it is usually better to use geo...

Geosynthetic Clay Liner is a kind of geosynthetic material specially used in waste landfill, underground reservoir, underground infrastructure construction and so on. Geosynthetic Clay Liner construction method: 1, Geosynthetic Clay Liner material weight is large, it is appropriate to use a shovel with waterproof blanket handling, laying. 2. Geosynthetic Clay Liner is linked by lap. 3. When the Geosynthetic Clay Liner is laid on a slope greater than 10%, the number of lap joints along the slope length should be reduced as far as possible, and the bentonite mat on the slope must exceed the slope foot line by more than 1500mm. 4. Any equipment used for laying Geosynthetic Clay Liner shall not run on the laid geotechnical materials. The outdoor temperature shall not be lower than 0 ° C or higher than 40 ° C when the bentonite waterproof blanket is installed. 5...

Filament geotextile has good mechanical function, good water permeability, corrosion resistance, aging resistance, isolation, filtration, drainage, protection, stability, reinforcement and other functions, can adapt to the uneven base, can resist the construction of external force creep small, long-term load can still maintain the original function. What works are suitable for filament geotextiles? Reinforcement in backfill, or panels for retaining walls. Construct parcel retaining walls or abutments. Reinforcement of the pond impermeable film road surface, repair the cracks on the road, to prevent reflection cracks on the road surface. An insulating layer of geotextiles between road, airport, railway slag and artificial rockfill and the foundation. The internal vertical or horizontal drainage of the earth dam, buried in the soil to dissipate the void water pressure. Drainage beh...
