en.Wedoany.com Reported - On April 20th, the concreting of the bottom slab base course for the expansion generator in the main building of the Tongchuan Compressed Air Energy Storage Project officially began. This marks the full commencement of core equipment foundation construction, laying the first foundation for the subsequent construction of the expansion generator base slab.
As a crucial underlying structural layer of the base slab, the base course evenly disperses equipment loads, prevents uneven settlement, and provides a stable load-bearing foundation for the expansion generator set. It also isolates groundwater and soil corrosion, enhancing foundation durability. A level base course working surface ensures the precision of subsequent processes such as rebar tying and formwork installation. Additionally, the base course can buffer operational vibrations, reducing unit fatigue and wear, serving as a fundamental safeguard for the long-term safe operation of the equipment.
To ensure the high-quality completion of the concreting task, the project team adhered to the quality philosophy of "Striving for excellence, achieving perfection the first time," meticulously planning, scientifically organizing, reasonably optimizing the construction sequence and methods, conducting thorough personnel work standard training, technical disclosure, and side station supervision, and strictly executing refined operations in accordance with technical plans, drawings, and specifications. Before concreting, the project department, in conjunction with the owner, supervisor, and other parties, inspected the pit base course acceptance, ensuring construction quality and safety. During the concreting process, segmented pouring and vibration were adopted, concrete supply, sampling, test block retention, and curing were diligently managed to guarantee the quality of the base course construction.
This project is the world's first 350 MW large-tank artificial cavern compressed air energy storage power station and the world's first project to build a gas storage cavern in limestone strata. It has been included in the national demonstration projects for green and low-carbon advanced technologies and one of the first batch of independent energy storage pilot projects in Shaanxi Province. Upon completion, it will reduce the demand for peak regulation support from the large power grid, promote the coordinated operation of various energy sources through complementarity, and enhance the consumption level of renewable energy.
In the next steps, the project department will continue to carry forward the spirit of the dedicated and pioneering electric power construction iron army, strictly control safety, quality, and schedule, and professionally, with high standards and lean methodology, advance all subsequent construction milestones to ensure the project's early commissioning and early benefits.
