Located in Jungar‑Banner, Ordos, Inner‑Mongolia Liangyun‑Animal‑Husbandry‑Co.,Ltd is a leading local agricultural‑industrial enterprise. Its million‑pig ecological‑circular‑industrial‑chain project is a key demonstration‑project for rural‑revitalization, integrating large‑scale planting, intelligent‑pig‑breeding, feed‑processing, slaughtering and cold‑chain‑logistics to build a modern green‑circular agricultural‑base Our scope covers steel‑structure construction for breeding‑houses and feed‑processing‑workshops. Adopting portal‑rigid‑frame steel‑system, the large‑span open‑space facilitates installation of intelligent‑breeding‑equipment, ventilation‑temperature‑control‑system and automatic‑feeding‑lines. With advantages of short‑construction‑period, flexible layout and anti‑corrosion performance, the steel‑workshop meets strict requirements of epidemic‑prevention, ventilation and thermal‑insulation for modern‑livestock‑breeding and provides solid foundation for the whole‑industrial‑chain.
The livestock‑breeding steel‑structure demands high‑standard anti‑corrosion, thermal‑insulation and snow‑resistance. Major construction‑challenges include batch‑fabrication of steel‑components for multi‑bay workshops, synchronous‑hoisting in different zones, high‑strength‑bolt installation for beam‑column‑joints, verticality‑calibration of integral‑frame and application of special anti‑corrosion‑coating for breeding‑environment. Situated on Ordos Plateau with frigid‑winter, heavy‑snow‑load and frequent wind‑sand‑erosion, the steel‑structure is mechanically‑checked according to cold‑climate building‑codes of Northern‑China. Hot‑dip‑galvanization plus special breeding‑grade anti‑corrosion finish‑coating are applied for primary‑secondary steel‑members against freeze‑thaw‑damage, wind‑sand‑erosion and corrosive‑moisture inside breeding‑houses. Complete thermal‑insulation enclosure‑system maintains constant indoor‑temperature for livestock‑production. BIM‑simulation optimizes component‑layout and hoisting‑sequence for efficient construction of large‑scale breeding‑park.
We undertook full‑scope steel‑structure construction for breeding‑houses and feed‑workshops, covering detailed‑design of portal‑rigid‑frame, factory‑prefabrication of steel‑columns‑and‑beams, shot‑blasting anti‑corrosion‑coating, foundation‑re‑survey, hoisting‑erection of steel‑columns, beam‑assembly‑lifting, final‑tightening of high‑strength‑bolts, field‑welding, elevation‑&‑verticality‑calibration and supplementary anti‑corrosion‑&‑fire‑protection painting. Strict quality‑control was implemented for component‑precision, weld‑non‑destructive‑testing, cold‑region anti‑corrosion construction and settlement‑monitoring. We delivered high‑quality steel‑works and contributed to the industrial‑upgrading of modern‑ecological‑animal‑husbandry and rural‑revitalization in Ordos.
