Steel silo foundation engineering construction process
The foundation construction of steel silo shares many similarities with high-rise buildings, but due to their unique design and structure, certain steps in the construction process are distinctive.
Foundation Engineering and Technological Breakthroughs in Steel Silo
In the modern material storage industry, steel silo have become an essential storage facility due to their efficient and sturdy design. Whether in grain storage, feed storage, or fertilizer storage, steel silos play an irreplaceable role in ensuring safe and efficient material management. However, to ensure their safe operation and efficient use, the quality of foundation engineering is crucial. This article explores the construction process of steel silo foundations and discusses how technological breakthroughs have resolved traditional challenges in silo construction.(What is a steel silo)
Construction Sequence of Steel Silo Foundations
The foundation construction of steel silo shares many similarities with high-rise buildings, but due to their unique design and structure, certain steps in the construction process are distinctive. The main steps in the foundation engineering process for steel silo are as follows:
Site Levelling and Surveying
The first step involves levelling the construction site and performing accurate surveying to prepare for the next stages.
Mechanical and Manual Excavation
Machinery is used to excavate the earth, and manual labor is employed for trenching and transporting soil.
Manual Trenching and Concrete Cushion Layer
After excavation, the trench is manually cleaned, ensuring it is free of debris. A concrete cushion layer is then poured to provide support for the foundation.
Brick Formwork and Base Construction
Brickwork is used as formwork around the foundation, followed by the application of leveling mortar to smooth the base, ensuring the surface is even.
Waterproofing and Protection Layer
To prevent moisture and temperature variations from affecting the cement inside the silo, the base and surrounding areas are treated with waterproofing materials and a protective waterproof layer is added.
Reinforcement Binding and Equipment Embedding
After the preliminary foundation work is completed, reinforcement bars are bound, and necessary equipment is embedded.
Concrete Pouring for the Base
Finally, the concrete is poured to complete the foundation construction.
These steps provide a stable base for the steel silo and lay the groundwork for the subsequent construction of the silo structure.
Application of Settlement Technology in Steel Silo Foundations
The special structural design of steel silo—symmetrical cylindrical bodies—requires careful attention to foundation settlement. Settlement issues are one of the major technical challenges in steel silos construction. Ensuring uniform settlement is essential to maintain the safety and stability of the silo.
Zhengzhou steel silo have introduced an innovative settlement foundation technology. This technology not only reduces the cost of foundation treatment but also ensures that the foundation settles evenly, adapting to different load conditions. By precisely controlling the settlement process, the risk of structural deformation or tilting caused by uneven settlement is minimized.
The tilt or collapse of steel silo often stems from a lack of understanding of settlement technology or improper welding practices and material usage. Therefore, fully understanding and applying proper settlement foundation techniques is crucial to ensuring the long-term safety and reliability of steel silos.
Waterproofing and Leak-Proofing Technology for Steel Silo
Cement inside the steel silos walls may undergo cement hardening due to temperature differences and moisture, which can affect the silo’s lifespan and the safety of material storage. To address this issue, Zhengzhou steel silo employ advanced waterproofing and leak-proofing technologies.
First, high-performance polymer waterproofing materials are used on the bottom of the silo for secondary waterproofing reinforcement. This effectively prevents moisture penetration, ensuring that materials stored inside the silo remain dry and secure. Additionally, the top of the silo base and foundation are treated with corrosion-resistant and waterproof materials to form a final barrier against water intrusion. This ensures that even under extreme weather conditions, the storage environment inside the silo remains intact.
With these waterproofing and leak-proofing measures, the physical properties of cement and other materials stored inside the steel silo remain stable within a temperature range from -50°C to 160°C. This technology effectively reduces the impact of moisture on material quality.
Efficient Discharge and Technological Innovations
Another key technical issue for steel silo is ensuring the complete discharge of materials. During storage, materials may clump or solidify, making it difficult to discharge them smoothly. To resolve this issue, steel silos have adopted several patented technologies. These technologies ensure that materials are discharged on demand and in a timely manner.
These patented technologies focus on two main aspects: ensuring the smooth flow of materials and improving discharge efficiency. The implementation of these technologies guarantees that the discharge rate of materials is very high. For steel silo with a capacity of 1-3 tons, the discharge emptying rate exceeds 99.9%, while for silos with capacities of 5-20 tons, the emptying rate reaches over 99.99%, significantly enhancing storage and operational efficiency.
Conclusion
The foundation engineering quality and technological standards directly influence the long-term performance of steel silo. steel silos have overcome many traditional construction challenges through innovative applications in settlement technology, waterproofing, leak-proofing, and efficient discharge systems. These technological advancements provide a solid foundation for the safe and efficient operation of steel silos.
As steel silos technology continues to evolve, the prospects for its application in various industries will expand. Steel silo will continue to play an important role in the storage of grain, feed, fertilizer, and cement. They offer efficient, economical, and environmentally friendly solutions for material storage.
