Application of steel sheet pile in construction field

Steel sheet piles, with their high strength, excellent waterproof performance and convenient construction methods, have become an important structural material widely used in the construction field. It not only serves the functions of soil retaining, waterproofing and support, but also has the advantages of reusability and environmental protection and energy conservation. It is one of the irreplaceable support systems in modern engineering construction.

1. Foundation and support engineering

In the construction of building foundations and underground structures, steel sheet pile walls are often used for deep foundation pit support, basement enclosure, underground parking lots, subway stations and tunnel projects, etc.
The continuous retaining wall structure formed by interlocking can effectively resist earth pressure and water pressure, prevent collapse and seepage, and ensure the safety and stability of the construction process.
Compared with traditional concrete support, steel sheet piles have a faster construction speed and occupy less land, making them particularly suitable for underground projects in narrow urban Spaces.


2. Ports and water conservancy projects

Steel sheet piles are particularly widely used in port terminals, DAMS, breakwaters, dry docks and revetment projects.
Its high strength, excellent sealing performance and corrosion resistance make it highly suitable for use in water-retaining, bank protection and flood control structures.
The commonly used Z-type sheet piles and hot rolled sheet piles have higher bending stiffness and sealing performance, and can be used for a long time in harsh environments such as dampness and salt spray.

3. Bridge and Road Engineering

In bridge foundation or road construction, steel sheet piles are often used as cofferdam structures, foundation pit support and slope protection retaining walls.
During construction, a closed cofferdam can be quickly formed in rivers or deep pits, providing a safe construction environment for bridge piers, piers or tunnels.
In addition, sheet piles can also be used to prevent riverbank erosion and roadbed sliding, enhancing the durability and stability of transportation infrastructure.

4. Flood control and drainage systems

In the fields of flood control projects and water resource management, the anti-seepage and waterproof performance of sheet piles is particularly outstanding.
Its tight lock mouth structure can effectively prevent groundwater seepage and is often used in projects such as flood control embankments, river regulation, reservoirs, sewage treatment plants and irrigation channels.
As an anti-seepage wall or cofferdam system, steel sheet pile structure is solid and easy to maintain, and can resist water pressure and earth pressure for a long time.

5. Temporary works and reusability

One of the greatest advantages of sheet piles is that they can be reused.
In temporary construction projects (such as cofferdams, foundation pit support, and pipeline excavation), sheet piles can be pulled out and recycled after the completion of the project for use in other projects.
This feature not only significantly saves construction costs but also conforms to the current trend of green and sustainable development in the construction industry.

Common types and Selection of sheet piles

Depending on the nature of the project and the force requirements, there are various forms of sheet piles to choose from

U-type sheet pile: Balanced structure, convenient construction, suitable for general support projects;

Z-type sheet pile: With high cross-sectional strength, it is suitable for deep foundation pits or Marine engineering.

Straight sheet piles: Commonly used in light anti-seepage structures;

hot rolled sheet pile: The lock joint is tight, with high strength, suitable for permanent structures;

Cold-formed sheet pile: Light in weight and low in cost, suitable for temporary projects.

Summary

steel sheet piles have been widely recognized in the modern construction field due to their high structural strength, flexible construction, good sealing performance and sustainable use.
