Definition
Sheet pile refers to interlocking structural elements (usually steel, but sometimes wood or synthetic materials) driven into the ground to provide earth retention and excavation support. 🏗️ Imagine it as a vertical wall made of connected panels. Unlike traditional walls, it's installed by driving each pile into the earth. Its primary function is to hold back soil and water. Think of it as a barrier preventing landslides or protecting construction sites from flooding. It's commonly used in waterfront construction, retaining walls, and cofferdams.
