Steel sheet pile is a kind of foundation construction material widely used in construction engineering. According to different uses and needs, it can be divided into U-shaped steel sheet pile, Z-shaped steel sheet pile, L-shaped steel sheet pile, S-shaped steel sheet pile, linear steel sheet pile, combined steel sheet pile, cap steel sheet pile and H-shaped steel sheet pile.

Common steel sheet piles and their applications As an important foundation engineering material, steel sheet piles play an important role in many fields due to their high strength, easy construction and reusability.

1. U-shaped steel sheet piles

U-shaped steel sheet piles have a large cross-sectional area and high strength, and are suitable for underground projects and earthwork support projects with high water pressure resistance. Due to their excellent pressure resistance, U-shaped steel sheet piles are often used in deep foundation pit support, river channel and coastal protection projects.

2. Z-shaped steel sheet piles

The locks of Z-shaped steel sheet piles are symmetrically distributed on both sides of the neutral axis, and the web is continuous, which greatly improves the section modulus and bending stiffness. They are often used in projects that require higher bending resistance.

3. L-shaped steel sheet piles

L-shaped steel sheet piles are mainly used for supporting embankments, dam walls, canal digging and trenching. Its section is light, the pile wall occupies a small space, the lock is in the same direction, and the construction is convenient.

4. S-shaped steel sheet piles

S-shaped steel sheet piles are also a common type with a specific cross-sectional shape and size, suitable for specific engineering needs.

5. Straight steel sheet piles

The cross-sectional shape of the straight steel sheet piles is straight, with a simple structure, convenient construction and strong bending resistance. They are widely used in civil engineering projects such as bridges and tunnels.

Application fields of steel sheet piles

1. River bank protection and flood control: Steel sheet piles are usually used in river bank protection, ship locks, sluice structures and flood control. Their advantages are easy construction on the water and long service life.

2. Ports and docks: Steel sheet piles are used in docks, unloading yards, embankment bank protection, retaining walls, retaining walls, breakwaters, diversion embankments, mooring posts, etc. in port construction.

3. Foundation pit support: Steel sheet pile engineering has significant advantages in the field of foundation pit support and can be used for foundation pit support of various types of buildings, roads, bridges and other projects.

4. Municipal engineering: Steel sheet piles are also widely used in municipal engineering, such as comprehensive pipe gallery construction.

5. Environmental protection: Steel sheet piles also play an important role in the field of environmental protection, such as sewage treatment and water quality improvement projects.
