en.Wedoany.com Reported - The prefabrication of all beam slabs for the G1816 Wuhai-Maqin Expressway Hesai Project, invested and constructed by CCCC First Highway Engineering Group, has been completed, marking a significant milestone for the project.

This project is a key construction initiative under Gansu Province's "14th Five-Year Plan" and Gannan Prefecture's "Highway Access for Every County" program. The main line spans approximately 105 kilometers, designed as a four-lane dual carriageway with a speed limit of 100 km/h. It is currently the longest highway project under construction and the largest in terms of investment within Gannan Prefecture. The project includes four beam yards, responsible for producing 4,989 beam slabs, including T-beams, box beams, and corrugated steel web beams. Facing construction challenges such as high altitude and significant temperature differences between day and night, the project team optimized the allocation of labor, machinery, and materials, and refined the construction organization design and plans. During construction, integral mobile hydraulic formwork was used to improve the efficiency of formwork installation, removal, and turnover. Stainless steel formwork and a cleaning and wiping process replaced traditional grinding methods, shortening the construction period while improving the appearance quality of the concrete. A full-cycle steam curing system was introduced, combined with intelligent temperature and humidity monitoring and fully enclosed curing sheds, to precisely control temperature and humidity, effectively preventing concrete cracks.

Upon completion, the project will connect six townships across Luqu, Xiahe, and Hezuo counties and cities, serving as a major transportation artery radiating to surrounding areas and a key corridor between Gansu, Qinghai, and Sichuan provinces. This project is of great significance for improving the regional road network structure, promoting ethnic unity, and driving regional economic development and rural revitalization.
