en.Wedoany.com Reported - The waterproofing node for the turbine hall of Unit 9 of the China Power Changshu 3×660MW Unit Expansion Project, under the EPC contract of China Energy Engineering Group East China Electric Power Engineering Institute, has been completed, marking the full transition of the unit's construction into the installation phase.

The roof of the turbine hall for Unit 9 of the Changshu project adopts a reinforced concrete roof slab with steel trusses and profiled steel sheets as the bottom formwork. It has a longitudinal span of 83 meters, a transverse span of 32 meters, a total height of 38.96 meters, and an operating floor height of 14.5 meters. As the core building of the project, the waterproofing construction quality of the turbine hall is directly related to the structural safety of the plant, the subsequent stable operation of equipment, and the overall service life of the project. The EPC project department prepared a specialized construction plan in advance and organized technical, safety, and construction departments to conduct technical briefings, overcoming difficulties such as a narrow construction site and dense crossover operations of large machinery. The completion of the turbine hall roof waterproofing node has formally created an enclosed space for the upper structure of the turbine hall, providing a safe working environment for the entry, installation, and commissioning of core equipment such as the steam turbine and generator.

In the next step, the EPC project department will advance construction tasks such as plant equipment installation and pipeline laying, strictly controlling quality and safety to ensure the smooth achievement of subsequent milestone targets.
