The main functions of steel sheet piles are:

1. The practical value of steel sheet piles is reflected in the innovative production of many new products, such as some special welded buildings; and metal plates made by hydraulic vibration pile drivers.

2. The development of special sealing and printing processes is a good example in this regard. For example, the HOESCH patent system, its appearance has opened up an important new field for steel sheet piles in pollution control.

3. Since steel sheet piles have been used as vertically sealed retaining walls to protect contaminated land, it has been found that steel sheet piles meet all requirements for preventing water leakage and pollution. The advantages of steel sheet piles as retaining walls have gradually been widely used in other fields.

Steel sheet piles are a type of steel with a lock, and its cross-section has a straight plate shape, groove shape Z shape, etc., with various sizes and interlocking forms. Common ones are the Larson type, Lackawanna type, etc. Its advantages are: high strength, easy to drive into hard soil layers; can be constructed in deep water, and inclined supports can be added to form a cage when necessary. Good waterproof performance can form cofferdams of various shapes as needed and can be reused many times, so it has a wide range of uses.

Application characteristics of steel sheet piles:

1. Handle and solve a series of problems that arise during excavation;

2. Simple construction and shortened construction period;

3. For construction tasks, it can reduce the requirements for space;

4. The use of steel sheet piles can provide the necessary safety and has strong timeliness (for disaster relief);

5. The use of steel sheet piles is not restricted by weather conditions; the process of using steel sheet piles, can simplify the complex procedures for checking the performance of materials or systems to ensure their adaptability, and good interchangeability, and can be reused.

6. It can be recycled and reused to save money.
