In support engineering, steel sheet piles are widely used because they offer advantages over other methods in terms of strength, safety, and convenience. More specifically, steel sheets offer the advantages of being lightweight yet strong, and their reduced space requirements are another advantage. However, the use of steel sheets also presents some other issues.

What are the disadvantages of using steel sheet piles?

1. Steel sheet piles can cause deformation in nearby areas during construction, as well as generate significant noise.

2. Improper placement of steel sheet piles can exacerbate deformation.

3. The use of steel sheet piles in deep foundation pits is limited.

4. After construction is complete, these steel sheet piles need to be pulled back. This can affect surrounding foundations, surrounding buildings, and surface soil, and can even cause cracks in the ground.

5. The joints of steel sheet piles are prone to breakage. To address this, workers must ensure that the joints have the same rigidity as the rest of the pile during construction.
