At 06:37 on June 2, 2026, the main structure of Cooling Tower #2 in Section II of the Shandong Liaocheng Xiangguang 2×660 MW cogeneration project—constructed by our company—was successfully topped out, marking a milestone achievement at a critical control point. This milestone has laid a solid foundation for the orderly progress of subsequent construction phases and the early commissioning of the project.

#2 Following the completion of the lower ring beam pouring for the cooling tower on December 14,2025, the project team united their efforts and worked around the clock. After 168 days and nights of intensive work, they successfully completed the full topping-out of the main structure to high standards and with remarkable efficiency. This cooling tower is a super-large-diameter reinforced concrete hyperbolic structure characterized by complex geometry, stringent construction precision requirements, substantial high-altitude workloads, and significant safety management challenges, making its construction process fraught with difficulties. Confronting these obstacles, the project team addressed them head-on through targeted strategies, leveraging scientific planning and strong commitment to overcome construction bottlenecks and steadily advance both quality and progress of the project.

To effectively strengthen the quality and safety safeguards of the project, innovative construction techniques were adopted, utilizing electric track trains combined with a layered pouring method. This approach significantly improved the coordination between construction processes, substantially enhanced concrete pouring efficiency and structural stability, and markedly reduced risks associated with high-altitude work. Standardized and meticulous control was implemented throughout the entire construction process, with on-site construction and safety personnel stationed continuously for dynamic monitoring. The quality control team strictly enforced the "three-inspection system," conducting rigorous checks and verification at every critical stage—including tower radius calibration, concrete mix proportions, pouring and vibration, and strength testing. All construction parameters strictly complied with design specifications and industry standards, ensuring precise control over the formation quality of the hyperbolic structure and comprehensive assurance of the cooling tower's structural stability, performance, and safety reliability.

This project is a large-scale coal-fired power unit carried over from the national 13th Five-Year Plan and currently under construction, also designated as a key major construction project in Shandong Province for 2024 and 2025. It serves as a core support initiative for regional energy supply security and industrial upgrading. Upon completion and commissioning, the project will further optimize the region's power generation mix, drive the clean, efficient, and intelligent transformation of the coal-fired power industry, strengthen local energy security foundations, comprehensively meet regional heating demands for residential and industrial use, and holds significant strategic importance for promoting high-quality local economic development and enhancing the regional energy security system.

The successful topping-out of Cooling Tower #2 has accelerated the project's early commissioning and power generation. This milestone marks a significant achievement in the construction process and stands as a vivid testament to the collective efforts, shared determination, and pragmatic commitment of all participating personnel.
