Wuhan Metropolitan Area Ring Expressway – Xiaogan South Section Smart Precast Yard
Project Name
Smart Precast Yard of Wuhan Metropolitan Area Ring Expressway – Xiaogan South Section (武汉都市圈环线高速孝感南段智慧梁场)
Location
Xiaogan South Section of the Wuhan Metropolitan Area Ring Expressway, Hanchuan City, Hubei Province, China. The section connects to the Hannan Yangtze River Bridge project . There are multiple smart precast yards across different construction sections, located in Hanchuan City and Xiaonan District .
Function
Serves as a centralized precast beam production facility for the expressway project. The smart yard features an automated management system for the full-cycle curing of precast box girders, significantly improving production efficiency and quality stability .
Key Specs
- Technology: Uses a four-stage curing process: “formwork curing → high-temperature steam curing → standard curing → spray curing,” integrated with an intelligent temperature and humidity control system. This reduces curing time per beam to 72 hours (approx. 30% efficiency gain) .
- Production: Produces 30-meter-long, 100-ton precast box girders .
Construction & Investment Entities
- Overall Project Investor: Hubei Jiaotou Expressway Development Co., Ltd. (湖北交投高速公路发展有限公司) .
- Section 3 Contractor (Smart Yard Included): China Railway Major Bridge Engineering Group (中铁大桥局) .
- Other Section Contractor: CCCC Fourth Harbor Engineering Co., Ltd. (中交四航局) .
- Supervision/Consultancy: Hubei Gaochuang Highway Engineering Consulting & Supervision Co., Ltd. (湖北省高创公路工程咨询监理有限公司); Zhejiang Highway & Waterway Engineering Supervision Co., Ltd. (浙江公路水运工程监理有限公司) .
Project Status (as of mid-2026)
The smart precast yard is fully operational . The first box girders were successfully erected in late 2025 . As of June 2026, the project is actively progressing with bridge substructure construction and safety management activities, such as flood control drills .
