en.Wedoany.com Reported - At 9:28 AM on May 6th, good news came from the Huainan Luohe Power Plant Phase IV 2×1000 MW ultra-supercritical double-reheat coal power project, constructed by China Energy Engineering Group Construction Co., Ltd. Following the successful topping out of the wind shell for Cooling Tower No. 7, the 144th section of concrete pouring for the high-level water collection Cooling Tower No. 8 was completed, and the shell wall was successfully capped. This marks the completion of the main structure for both cooling towers of the project, achieving the key breakthrough of "Dual Towers Rising Simultaneously."
Cooling Tower No. 8 is a reinforced concrete hyperbolic shell structure with a total height of 199.721 meters, poured in 144 sections, each approximately 1.3 meters high. It uses C40W8F150 waterproof and frost-resistant concrete, with the thinnest part of the shell being only 0.25 meters, demanding high construction precision and safety control. The project adopted the attached tripod formwork turnover process, complemented by a hydraulic climbing flat-top bridge and construction hoist, establishing an efficient and stable three-dimensional construction system that enables coordinated progress in material transport, personnel access, and shell wall construction.
During the construction process, the project team adhered to meticulous control, strictly managing key processes such as surveying and setting out, rebar tying, formwork erection, and concrete pouring. Through dynamic monitoring of the tower radius and verticality using a total station, errors were controlled within the specified range, ensuring excellent shell wall formation quality and smooth structural alignment. Facing adverse conditions such as strong winds and temperature variations, the team scientifically organized construction, optimized resource allocation, and ensured a continuous and stable construction pace.
Building on the construction experience from Tower No. 7, the project team systematically optimized the process flow and safety control measures, achieving efficient replication of technical achievements, significantly improving construction efficiency and organizational levels, and providing strong support for the smooth topping out of Tower No. 8.
Both cooling towers utilize high-level water collection cooling technology. Once completed, they will effectively reduce the energy consumption of the circulating water system, providing a crucial guarantee for the safe, stable, efficient, and clean operation of the million-kilowatt units. The simultaneous completion of the two towers signifies a phased victory in the project's hydraulic structure construction, creating favorable conditions for subsequent system installation and overall commissioning.
In the next step, the project department will focus on the established goals, continuously advancing the auxiliary works and system improvement for the cooling towers, strictly adhering to safety and quality baselines, comprehensively accelerating the construction pace, and striving to build a green, efficient, high-quality, and premium energy project.
