On April 3, 2025, the pouring of the compressor base concrete for Unit 2 of the Jiangsu Guoxin Huai’an salt cavern compressed air energy storage power generation project was successfully completed. As the core supporting structure of the compressor unit, this base has a top plate thickness of 2 meters; the precision requirements for the embedded bolt sleeves are extremely high. Its high-quality completion lays a solid foundation for the subsequent installation of equipment. During the construction process, the project team overcame technical challenges and strictly controlled the construction quality. The compressor base bears the long-term operating loads of the machine set, which weighs hundreds of tons. The thickness of the top slab of this base is 2 meters, with a single pouring volume of concrete exceeding 250 cubic meters. The project team employed techniques such as layered continuous pouring and a temperature monitoring system to effectively avoid the risk of temperature-induced cracks. At the same time, the positioning accuracy of the bolt sleeves embedded in the base is subject to strict requirements; the team used equipment such as total stations for real-time positioning monitoring to ensure that both the verticality and horizontal deviation of the sleeves remained within the specified limits, thus providing a solid guarantee for the precise installation of the compressor. Once the casting of the compressor base is completed, Unit 2 will enter the phase of main unit lifting and commissioning. The high-precision construction of the base significantly reduces the risk of installation errors, eliminating the need for rework that occurs in traditional methods due to base settlement or bolt misalignment. The project team stated that the precision of the base directly affects the operational stability of the compressor. The high-standard completion achieved this time creates favorable conditions for a \"zero-defect\" installation of the subsequent compressed air system, with the potential to accelerate the overall project timeline by more than 20%.
