The pouring of the mass concrete for the 3 silo foundations of the Shanxi Broccoli Gasification Project was successfully completed

Recently, with the final batch of concrete precisely poured into the foundations of the silos, the pouring of the mass concrete for the foundations of the 3 silos in the Shanxi Cauliflower Gasification Project was successfully completed. Two pump trucks at the site ensured precise concrete distribution, 20 concrete mixer trucks moved around in an orderly manner along the temporary access roads, and over 120 construction workers worked in shifts of three; after 50 hours of continuous work, they successfully completed the task of pouring 3,400 cubic meters of concrete. The coal storage silos are the key storage and transportation facilities for the Shanxi Cauliflower Gasification Project. Once completed, the three silos will have a combined coal storage capacity of 14,000 cubic meters, bringing the total capacity to over 40,000 cubic meters, which will significantly enhance the storage and transportation capabilities of the main facilities. The ring foundation of the silo poured this time has a diameter of 24 meters and an average thickness of 1.6 meters. As the core structural element that bears the load of the silo, the quality of its pouring is directly related to the safety of storage and transportation in later stages as well as the stable operation of the main equipment; it represents a key milestone in the project’s construction. During the construction process, the project team faced two challenges: first, a rain warning was issued by the meteorological service, and second, repairs to the main roads in the construction area made the transport routes unusable. To address this challenge, the team built rain shelters in advance to cover the pouring area and stocked up on over 200 pieces of rainproof cloth ； Coordinate all construction areas simultaneously, optimize vehicle routes, create temporary construction passages, and assign 10 traffic coordinators to guide tank trucks, ensuring zero disruptions in concrete transportation. The silo is constructed using the \"layered continuous pouring\" method, with each layer being 30 centimeters thick; the time interval between layers is kept within 2 hours to prevent the formation of cold joints ； A customized concrete mix with low heat of hydration was developed, incorporating mineral powder and an efficient retarding agent. 28 temperature sensors were installed to monitor temperatures in real time, ensuring that the temperature difference between the interior and exterior remained within 25°C and thus preventing cracks effectively. The supervision unit remains on site throughout the process, taking random samples every hour to check the concrete slump and ensuring that the pouring quality meets the design standards.
