No.5 Farm of Laohekou Muyuan‑Animal‑Husbandry‑Co.,Ltd is a key modern‑large‑scale pig‑breeding‑base in Laohekou, Xiangyang. Committed to constructing standardized, intelligent and enclosed ecological‑breeding‑facilities, the project promotes the whole‑industrial‑chain development of pig‑farming along Han‑River and boosts rural‑revitalization and animal‑husbandry‑upgrading. Our construction‑scope covers steel‑structure‑main‑body for fattening‑houses, breeding‑workshops and supporting‑warehouses. Adopting portal‑rigid‑frame steel‑system, the large‑span open‑indoor‑space supports full‑set intelligent‑breeding‑equipment, including automatic‑feeding, ventilation‑temperature‑control and manure‑treatment‑systems. With fast‑construction‑speed and excellent anti‑corrosion‑performance, the steel‑workshop meets strict‑requirements of epidemic‑prevention, thermal‑insulation and moisture‑proof, providing solid‑foundation for large‑scale intelligent‑pig‑breeding.
The livestock‑breeding‑steel‑structure requires high‑standard moisture‑proof, anti‑corrosion and snow‑load‑bearing‑capacity. Major construction‑challenges include batch‑fabrication of steel‑components for multi‑bay workshops, synchronous‑hoisting in different zones, high‑precision high‑strength‑bolt installation for beam‑column‑joints, welding‑deformation‑control of long‑span roof‑beams and application of special anti‑corrosion‑coating for breeding‑environment. Located in Han‑River‑Plain of Laohekou‑Xiangyang with distinct‑four‑seasons and hot‑humid‑summer‑rainfall, the steel‑structure is mechanically‑checked in accordance with central‑China agricultural‑building‑codes. Hot‑dip‑galvanization plus breeding‑grade anti‑corrosion finish‑coating are applied for primary‑secondary steel‑members against corrosive‑moisture. Complete roof‑thermal‑insulation‑system guarantees constant indoor‑temperature for pig‑houses. BIM‑simulation optimizes component‑layout and hoisting‑sequence for multi‑building parallel‑construction.
We undertook full‑scope steel‑structure‑construction of breeding‑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, anti‑corrosion‑construction under humid‑condition and settlement‑monitoring. We delivered high‑quality steel‑works and contributed to the high‑quality‑development of modern‑ecological‑animal‑husbandry industry in Xiangyang.
