The use of hot-rolled U-shaped steel sheet piles for large buildings

U-shaped sheet piles are a new technology product newly introduced from the Netherlands, Southeast Asia and other places. Now they are widely used in the entire Pearl River Delta and Yangtze River Delta. Application areas: large rivers, sea cofferdams, central river regulation, foundation pit construction, Highways, bridges, municipal projects and third-level wharf reconstruction
Introduction to the application advantages of U-shaped sheet piles:
1. Large retaining section. U-shaped prestressed concrete sheet pile single pile retaining section length reaches 1 meter, which is far far from traditional sheet piles and ordinary precast pile types.
2. The cross-section stress structure form is excellent. The U-shaped structural cross-section design is adopted to increase the cross-sectional height and cross-sectional moment of inertia, thereby improving the stress performance of the structure.
3. The economic benefits are obvious. The U-shaped structure is adopted, which greatly reduces the amount of concrete used in this pile type compared with ordinary sheet piles at the same cross-section height. At the same time, the U-shaped sheet pile adopts a prestressed structure design, which greatly reduces the stress and reinforcement requirements on the premise of meeting the structural stress reinforcement requirements. The amount of reinforcement in the structure is increased and the cost is reduced. At the same time, the soil retaining width of this pile type single pile reaches 1 meter, which is far far from the ordinary pile type. Based on the above characteristics, the cost of U-shaped prestressed concrete sheet piles is about 30% lower than that of traditional ordinary sheet piles, which has good economic benefits.
4. Model type. The types of U-shaped prestressed concrete sheet piles can be flexibly selected to meet project needs by adopting different section heights, reinforcement forms, reinforcement quantities and pile lengths according to the mechanical performance requirements of the pile type. Achieve optimization of cross-section structure and maximize economic benefits.
5. The construction period is short. U-shaped prestressed concrete sheet piles adopt factory prefabricated mode, and the construction site is mechanized to construct the sheet pile wall, which greatly shortens the construction period compared with traditional methods.
6. Construction technology, wide applicable geological range, and beautiful cross-section after pile formation
