The use of high-grade cement and a high degree of concrete with a few concrete additives, so that the concrete strength of C40 or more, its performance with wear resistance, corrosion resistance, anti-penetration and other advantages; reinforced mesh welding technology by point welding, force. Each board of the total load capacity of up to 1000 kg, each single load 400 kg (refers to the large hole plate), the installation only need to support the four corners of the board can be. The size of the voided manure is reasonable, the corner of the hole is arc-shaped, does not hurt the trotters, holes on the small under the big ladder shape, leakage of fecal effect is good, basically no water erosion, that is, saving manpower, More importantly, to reduce the burden of sewage treatment. The use of fecal dregs built high-bed pig house, summer only open the window, the wind from the bottom down the temperature, to solve the summer heat when the pig does not eat long economic losses. When the temperature is low in the winter, the water heating device is set up under the fouling floor, and the temperature is quick and the pig is dry and comfortable, which is beneficial to the growth of the pig.
