【Haichuan’s Visual Explanation】The Application of Composite Steel Sheet Piles
Thread Content
There is such high enthusiasm for steel sheet piles that sites using them for trench excavation can be seen almost everywhere. After being used extensively, some instances of abuse emerged, and the limitations of steel sheet piles became apparent; for example, whether they can be used in deeper foundation pits Can we use fewer anchor bolts and internal supports? Can it be made to deform less?
These problems were resolved to a certain extent after the advent of composite steel sheet piles. There are two common types of composite steel sheet piles: one is U-shaped steel sheet piles combined with H-shaped steel, and the other is U-shaped steel sheet piles combined with steel pipes. Among them, U-shaped steel sheet piles + H-shaped steel are likely to be more common and used more frequently. After combination, both stiffness and strength increase significantly, the ability to control displacement improves, and it can be applied to deeper foundation pits; it can maintain a certain level of deformation with fewer anchor rods or internal supports. At present, Jiangsu and Zhejiang have issued technical standards for composite steel sheet piles, providing a basis for their use.
It keeps evolving and improving within applications – the creativity of the working people is truly infinite!
